1.General descriptionThe PCA9533is a 4-bit I 2C-bus and SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.The PCA9533 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. The LED brightness is controlled by setting the blink rate high enough (>100Hz)that the blinking cannot be seen and then using the duty cycle to vary the amount of time the LED is on and thus the average current through the LED.The initial setup sequence programs the two blink rates/duty cycles for each individual PWM.From then on,only one command from the bus master is required to turn individual LEDs ON, OFF , BLINK RATE 1 or BLINK RATE 2. Based on the programmed frequency and duty cycle, BLINK RATE 1 and BLINK RATE 2 will cause the LEDs to appear at a different brightness or blink at periods up to 1.69second. The open-drain outputs directly drive the LEDs with maximum output sink current of 25mA per bit and 100mA per package.To blink LEDs at periods greater than 1.69second the bus master (MCU, MPU, DSP ,chip set, etc.) must send repeated commands to turn the LED on and off as is currently done when using normal I/O expanders like the NXP Semiconductors PCF8574 or PCA9554. Any bits not used for controlling the LEDs can be used for General Purpose parallel Input/Output (GPIO)expansion,which provides a simple solution when additional I/O is needed for ACPI power switches, sensors, push-buttons, alarm monitoring, fans,etc.The Power-On Reset (POR) initializes the registers to their default state, causing the bits to be set HIGH (LED off).Due to pin limitations, the PCA9533 is not featured with hardware address pins. The PCA9533/01 and the PCA9533/02 have different fixed I 2C-bus addresses allowing operation of both on the same bus.2.FeaturesI 4 LED drivers (on, off, flashing at a programmable rate)I Two selectable, fully programmable blink rates (frequency and duty cycle) between 0.591Hz and 152Hz (1.69second and 6.58milliseconds)I 256 brightness stepsI Input/outputs not used as LED drivers can be used as regular GPIOs I Internal oscillator requires no external components I I 2C-bus interface logic compatible with SMBusPCA95334-bit I 2C-bus LED dimmerRev. 03 — 27 April 2009Product data sheetI Internal power-on resetI Noise filter on SCL/SDA inputsI 4 open-drain outputs directly drive LEDs to 25mA I Edge rate control on outputs I No glitch on power-up I Supports hot insertion I Low standby currentI Operating power supply voltage range of 2.3V to 5.5V I 0Hz to 400kHz clock frequencyIESD protection exceeds 2000V HBM per JESD22-A114, 150V MM per JESD22-A115 and 1000V CDM per JESD22-C101I Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100mA I Packages offered: SO8, TSSOP8 (MSOP8)3.Ordering information3.1Ordering optionsTable 1.Ordering informationType numberPackage NameDescriptionVersion PCA9533D/01SO8plastic small outline package; 8leads;body width 3.9mmSOT96-1PCA9533D/02PCA9533DP/01TSSOP8plastic thin shrink small outline package; 8leads;body width 3mmSOT505-1PCA9533DP/02Table 2.Ordering optionsType number Topside mark Temperature range PCA9533D/01P9533/1T amb =−40°C to +85°C PCA9533D/02P9533/2T amb =−40°C to +85°C PCA9533DP/01P33/1T amb =−40°C to +85°C PCA9533DP/02P33/2T amb =−40°C to +85°C4.Block diagram5.Pinning information5.1Pinning5.2Pin descriptionRemark:Only one I/O shown for clarity.Fig 1.Block diagram of PCA9533002aae626I 2C-BUS CONTROLINPUT FILTERSPCA9533POWER-ON RESETSCL SDAV DDV SSLEDnOSCILLATORPRESCALER 1REGISTERPRESCALER 0REGISTER PWM1REGISTERPWM0REGISTER INPUT REGISTERLED SELECT (LSn)REGISTERBLINK0BLINK11Fig 2.Pin configuration for SO8Fig 3.Pin configuration for TSSOP8PCA9533D/01PCA9533D/02LED0V DD LED1SDA LED2SCL V SSLED3002aae62412346587LED0V DD LED1SDA LED2SCL V SSLED3002aae62512346587PCA9533DP/01PCA9533DP/02Table 3.Pin descriptionSymbol Pin Description LED01LED driver 0LED12LED driver 1LED23LED driver 2V SS 4supply ground LED35LED driver 36.Functional descriptionRefer to Figure 1 “Block diagram of PCA9533”.6.1Device addressFollowing a START condition, the bus master must output the address of the slave it is accessing. The address of the PCA9533/01 is shown in Figure 4 and the address of PCA9533/02 is shown in Figure 5.The last bit of the address byte defines the operation to be performed.When set to logic 1a read is selected, while a logic 0 selects a write operation.6.2Control registerFollowing the successful acknowledgement of the slave address,the bus master will send a byte to the PCA9533, which will be stored in the Control register.The lowest 3bits are used as a pointer to determine which register will be accessed.If the Auto-Increment (AI) flag is set, the three low order bits of the Control register are automatically incremented after a read or write. This allows the user to program theregisters sequentially.The contents of these bits will rollover to ‘000’after the last register is accessed.When Auto-Increment flag is set (AI =1) and a read sequence is initiated, the sequence must start by reading a register different from the INPUT register (B2B1B0≠000).Only the 3 least significant bits are affected by the AI flag. Unused bits must be programmed with zeroes.SCL 6serial clock line SDA 7serial data line V DD8supply voltageTable 3.Pin description …continuedSymbol Pin Description Fig 4.PCA9533/01 slave address Fig 5.PCA9533/02 slave address002aae627111R/Wslave address002aae6281111R/Wslave address Reset state: 00hFig 6.Control registerB0002aad744000AI 0B2B1register addressAuto-Incrementflag6.2.1Control register definition6.3Register descriptions6.3.1INPUT - Input registerThe INPUT register reflects the state of the device pins.

LEDn output pin is HIGH when the output is programmed as high-impedance,and LOW when the output is programmed LOW through the ‘LED selector’ register. The output can be pulse-width controlled when PWM0 orPWM1 are used.6.5Power-on resetWhen power is applied to V DD, an internal Power-On Reset (POR) holds the PCA9533 ina reset condition until V DD has reached V POR.At that point,the reset condition is releasedand the PCA9533 registers are initialized to their default states, all the outputs in theOFF state. Thereafter, V DD must be lowered below 0.2V to reset the device.7.Characteristics of the I 2C-busThe I 2C-bus is for 2-way,2-line communication between different ICs or modules.The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must beconnected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy.7.1Bit transferOne data bit is transferred during each clock pulse.The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as control signals (see Figure 7).7.1.1START and STOP conditionsBoth data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOWtransition of the data line while the clock is HIGH is defined as the START condition (S).A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP condition (P) (see Figure 8).7.2System configurationA device generating a message is a ‘transmitter’; a device receiving is the ‘receiver’. The device that controls the message is the ‘master’ and the devices which are controlled by the master are the ‘slaves’ (see Figure 9).Fig 7.Bit transfermba607data line stable;data validchange of data allowedSDASCLFig 8.Definition of START and STOP conditionsmba608SDASCLPSTOP conditionSSTART condition7.3AcknowledgeThe number of data bytes transferred between the START and the STOP conditions from transmitter to receiver is not limited. Each byte of eight bits is followed by oneacknowledge bit. The acknowledge bit is a HIGH level put on the bus by the transmitter,whereas the master generates an extra acknowledge related clock pulse.A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge clock pulse,so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse; set-up and hold times must be taken into account.A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a STOP condition.Fig 9.System configuration002aaa966MASTER TRANSMITTER/RECEIVERSLAVE RECEIVERSLAVETRANSMITTER/RECEIVERMASTER TRANSMITTERMASTER TRANSMITTER/RECEIVERSDA SCLI 2C-BUS MULTIPLEXERSLAVEFig 10.Acknowledgement on the I 2C-bus002aaa987S START condition9821clock pulse for acknowledgementnot acknowledgeacknowledgedata output by transmitterdata output by receiverSCL from master7.4Bus transactionsFig 11.Write to register0ASslave address (PCA9533/01)START condition R/Wacknowledge from slave002aae629AI0B2B1B00command byteAacknowledge from slave12345678SCL9SDA DATA 1Awrite to registerdata out from portt v(Q)acknowledge from slaveDATA 1 VALIDdata to register111Fig 12.Read from register110AS1START conditionR/Wacknowledge from slave002aae630Aacknowledge from slaveSDA APacknowledge from masterdata from registerDATA (first byte)slave address (PCA9533/01)STOP conditionS(repeated)START condition (cont.)(cont.)1AR/W acknowledge from slaveslave address (PCA9533/01)at this moment master-transmitter becomes master-receiver and slave-receiver becomes slave-transmitterNA no acknowledgefrom masterdata from register DATA (last byte)command byte 0AI0B2B10B0Auto-Increment register address if AI = 1111Remark:This figure assumes the command byte has previously been programmed with 00h.Fig 13.Read input port register111AS1START conditionR/Wacknowledge from slave002aae631Aacknowledge from masterSDA NA read fromportdata intoportPt h(D)data from port no acknowledge from masterdata from port DATA 4slave address (PCA9533/01)DATA 1STOP conditionDATA 2DATA 3DATA 4t su(D)DATA 18.Application design-in information8.1Minimizing I DD when the I/Os are used to control LEDsWhen the I/Os are used to control LEDs, they are normally connected to V DD through a resistor as shown in Figure 14. Since the LED acts as a diode, when the LED is off the I/O V I is about 1.2V less than V DD . The supply current, I DD , increases as V I becomes lower than V DD and is specified as ∆I DD in Table 13 “Static characteristics”.Designs needing to minimize current consumption, such as battery power applications,should consider maintaining the I/O pins greater than or equal to V DD when the LED is off.Figure 15 shows a high value resistor in parallel with the LED.Figure 16 shows V DD less than the LED supply voltage by at least 1.2V . Both of these methods maintain the I/O V I at or above V DD and prevents additional supply current consumption when the LED is off.Fig 14.Typical applicationPCA9533LED0LED1SDA SCL5 VI 2C-BUS/SMBusMASTER002aae632SDASCLV DDV SS5 VLED2LED310 k Ω10 k ΩFig 15.High value resistor in parallel withthe LEDFig 16.Device supplied by a lower voltage002aac189LEDV DDLEDn 100 k ΩV DD002aac190LEDV DDLEDn3.3 V5 V8.2Programming exampleThe following example will show how to set LED0and LED1off.It will set LED2to blink at 1Hz at a 50% duty cycle.

There is no single soldering method that isideal for all IC packages. Wave soldering is often preferred when through-hole andSurface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is notsuitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and highdensities that come with increased miniaturization.15.2Wave and reflow solderingWave soldering is a joining technology in which the joints are made by solder coming froma standing wave of liquid solder. The wave soldering process is suitable for the following:•Through-hole components•Leaded or leadless SMDs, which are glued to the surface of the printed circuit boardNot all SMDs can be wave soldered. Packages with solder balls, and some leadlesspackages which have solder lands underneath the body, cannot be wave soldered. Also,leaded SMDs with leads having a pitch smaller than ~0.6mm cannot be wave soldered,due to an increased probability of bridging.The reflow soldering process involves applying solder paste to a board, followed bycomponent placement and exposure to a temperature profile. Leaded packages,packages with solder balls, and leadless packages are all reflow solderable.Key characteristics in both wave and reflow soldering are:•Board specifications, including the board finish, solder masks and vias•Package footprints, including solder thieves and orientation•The moisture sensitivity level of the packages•Package placement•Inspection and repair•Lead-free soldering versus SnPb soldering15.3Wave solderingKey characteristics in wave soldering are:•Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components areexposed to the wave•Solder bath specifications, including temperature and impurities15.4Reflow solderingKey characteristics in reflow soldering are:•Lead-free versus SnPb soldering;note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure24) than a SnPb process, thusreducing the process window•Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board•Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peaktemperature is high enough for the solder to make reliable solder joints(a solder pastecharacteristic). In addition, the peak temperature must be low enough that thepackages and/or boards are not damaged. The peak temperature of the packagedepends on package thickness and volume and is classified in accordance withTable15 and16Table 15.SnPb eutectic process (from J-STD-020C)Package thickness (mm)Package reflow temperature (°C)Volume (mm3)< 350≥ 350< 2.5235220≥ 2.5220220Table 16.Lead-free process (from J-STD-020C)Package thickness (mm)Package reflow temperature (°C)Volume (mm3)< 350350 to 2000> 2000 < 1.62602602601.6 to2.5260250245> 2.5250245245Moisture sensitivity precautions, as indicated on the packing, must be respected at alltimes.Studies have shown that small packages reach higher temperatures during reflowsoldering, see Figure24.For further information on temperature profiles, refer to Application Note AN10365“Surface mount reflow soldering description”.16.AbbreviationsMSL: Moisture Sensitivity LevelFig 24.Temperature profiles for large and small components001aac844temperaturetimeminimum peak temperature = minimum soldering temperaturemaximum peak temperature = MSL limit, damage levelpeak temperatureTable 17.AbbreviationsAcronym DescriptionACPI Advanced Configuration and Power Interface CDM Charged Device Model DSP Digital Signal Processor DUT Device Under Test ESD ElectroStatic Discharge GPIO General Purpose Input/Output HBM Human Body Model I 2C-bus Inter-Integrated Circuit bus LED Light Emitting Diode MCU MicroController Unit MM Machine Model MPU MicroProcessor Unit POR Power-On ResetRC Resistor-Capacitor network SMBusSystem Management Bus。

1.General descriptionThe PCA9626 is an I 2C-bus controlled 24-bit LED driver optimized for voltage switch dimming and blinking 100mA Red/Green/Blue/Amber (RGBA) LEDs. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97kHz with a duty cycle that is adjustable from 0% to 99.6% to allow the LED to be set to a specific brightness value. An additional 8-bit resolution (256 steps)group PWM controller has both a fixed frequency of 190Hz and an adjustable frequency between 24Hz to once every 10.73seconds with a duty cycle that is adjustable from 0%to 99.6% that is used to either dim or blink all LEDs with the same value.Each LED output can be off, on (no PWM control), set at its individual PWM controller value or at both individual and group PWM controller values.The PCA9626operates with a supply voltage range of 2.3V to 5.5V and the 100mA open-drain outputs allow voltages up to 40V .The PCA9626 is one of the first LED controller devices in a new Fast-mode Plus (Fm+)family.Fm+devices offer higher frequency (up to 1MHz)and more densely populated bus operation (up to 4000pF).The active LOW Output Enable input pin (OE)blinks all the LED outputs and can be used to externally PWM the outputs,which is useful when multiple devices need to be dimmed or blinked together without using software control.Software programmable LED Group and three Sub Call I 2C-bus addresses allow all or defined groups of PCA9626 devices to respond to a common I 2C-bus address, allowing for example, all red LEDs to be turned on or off at the same time or marquee chasing effect, thus minimizing I 2C-bus commands. Seven hardware address pins allow up to 126devices on the same bus.The Software Reset (SWRST) Call allows the master to perform a reset of the PCA9626through the I 2C-bus,identical to the Power-On Reset (POR)that initializes the registers to their default state causing the output NAND FETs to be OFF (LED off). This allows an easy and quick way to reconfigure all device registers to the same condition.In addition to these features found in PCA9633, PCA9634, PCA9635, PCA9622 andPCA9624,a new feature to control LED output pattern is incorporated in the PCA9626.A new control byte called ‘Chase Byte’allows enabling or disabling of selective LED outputs depending on the value of the Chase Byte. This feature greatly reduces the number of bytes to be sent to the PCA9626 when repetitive patterns need to be displayed as in creating a marquee chasing effect.If the PCA9626 on-chip 100mA NAND FETs do not provide enough current or voltage to drive the LEDs,then the PCA9635and the PCA9635with larger current or higher voltage external drivers can be used.PCA962624-bit Fm+ I 2C-bus 100 mA 40 V LED driverRev. 02 — 31 August 2009Product data sheet2.FeaturesI24 LED drivers.

V SS pins mustbe connected to supply ground for proper device operation. For enhanced thermal, electrical, and boardlevel performance, the exposed pad needs to be soldered to the board using a corresponding thermal padon the board and for proper heat conduction through the board,thermal vias need to be incorporated in thePCB in the thermal pad region.7.Functional descriptionRefer to Figure 1 “Block diagram of PCA9626”.7.1Device addressesFollowing a START condition, the bus master must output the address of the slave it isaccessing.There are a maximum of 128 possible programmable addresses using the 7 hardwareaddress pins. T wo of these addresses, Software Reset and LED All Call, cannot be usedbecause their default power-up state is ON, leaving a maximum of 126 addresses. Usingother reserved addresses, as well as any other Sub Call address, will reduce the totalnumber of possible addresses even further.7.1.1Regular I2C-bus slave addressThe I2C-bus slave address of the PCA9626 is shown in Figure4. To conserve power, nointernal pull-up resistors are incorporated on the hardware selectable address pins andthey must be pulled HIGH or LOW externally.Remark:Using reserved I2C-bus addresses will interfere with other devices,but only if thedevices are on the bus and/or the bus will be open to other I2C-bus systems at some laterdate. In a closed system where the designer controls the address assignment theseaddresses can be used since the PCA9626 treats them like any other address. TheLED All Call, Software Rest and PCA9564 or PCA9665 slave address (if on the bus) cannever be used for individual device addresses.•PCA9626 LED All Call address (1110000) and Software Reset (00000110) whichare active on start-up•PCA9564 (0000000) or PCA9665 (1110000) slave address which is active onstart-up•‘reserved for future use’ I2C-bus addresses (0000011, 11111XX)•slave devices that use the 10-bit addressing scheme (11110XX)•slave devices that are designed to respond to the General Call address (0000000)•High-speed mode (Hs-mode) master code (00001XX)Fig 4.Slave addressR/W002aab319 A6A5A4A3A2A1A0hardware selectableslave addressThe last bit of the address byte defines the operation to be performed.When set to logic 1a read is selected, while a logic 0 selects a write operation.7.1.2LED All Call I 2C-bus address•Default power-up value (ALLCALLADR register): E0h or 1110000•Programmable through I 2C-bus (volatile programming)•At power-up,LED All Call I 2C-bus address is enabled.PCA9626sends an ACK whenE0h (R/W =0) or E1h (R/W =1) is sent by the master.See Section 7.3.9 “ALLCALLADR, LED All Call I 2C-bus address” for more detail.Remark:The default LED All Call I 2C-bus address (E0h or 1110000) must not be used as a regular I 2C-bus slave address since this address is enabled at power-up. All of the PCA9626s on the I 2C-bus will acknowledge the address if sent by the I 2C-bus master.7.1.3LED Sub Call I 2C-bus addresses• 3 different I 2C-bus addresses can be used •Default power-up values:–SUBADR1 register: E2h or 1110001–SUBADR2 register: E4h or 1110010–SUBADR3 register: E8h or 1110100•Programmable through I 2C-bus (volatile programming)•At power-up, Sub Call I 2C-bus addresses are disabled. PCA9626 does not send anACK when E2h (R/W =0) or E3h (R/W =1), E4h (R/W =0) or E5h (R/W =1), or E8h (R/W =0) or E9h (R/W =1) is sent by the master.See Section 7.3.8 “SUBADR1 to SUBADR3, I 2C-bus subaddress 1to 3” for more detail.Remark:The default LED Sub Call I 2C-bus addresses may be used as regular I 2C-bus slave addresses as long as they are disabled.7.1.4Software Reset I 2C-bus addressThe address shown in Figure 5 is used when a reset of the PCA9626 needs to beperformed by the master. The Software Reset address (SWRST Call) must be used with R/W =logic 0. If R/W =logic 1, the PCA9626 does not acknowledge the SWRST. See Section 7.6 “Software reset” for more detail.Remark:The Software Reset I 2C-bus address is a reserved address and cannot be used as a regular I 2C-bus slave address or as an LED All Call or LED Sub Call address.Fig 5.Software Reset address002aab41611R/W7.2Control registerFollowing the successful acknowledgement of the slave address, LED All Call address or LED Sub Call address, the bus master will send a byte to the PCA9626, which will be stored in the Control register.The lowest 6bits are used as a pointer to determine which register will be accessed (D[5:0]). The highest bit is used as Auto-Increment Flag (AIF).This bit along with the MODE1register bit 5and bit 6provide the Auto-Increment feature.Bit 6 of the Control register is not used.When the Auto-Increment Flag is set (AIF =logic 1), the six low order bits of the Control register are automatically incremented after a read or write. This allows the user to program the registers sequentially. Four different types of Auto-Increment are possible,depending on AI1 and AI0 values of MODE1 register.[1]AI1 and AI0 come from MODE1 register.Remark:Other combinations not shown in Table 3(AIF +AI[1:0]=001b,010b,011b and 111b) are reserved and must not be used for proper device operation.AIF +AI[1:0]=000b is used when the same register must be accessed several times during a single I 2C-bus communication, for example, changes the brightness of a single LED. Data is overwritten each time the register is accessed during a write operation.AIF +AI[1:0]=100b is used when all the registers must be sequentially accessed, for example, power-up programming.reset state = 80hRemark:The Control register does not apply to the Software Reset I 2C-bus address.Fig 6.Control registerTable 3.Auto-Increment options AIF AI1[1]AI0[1]Function 000no Auto-Increment100Auto-Increment for all registers.D[5:0]roll over to 0h after the last register 26h is accessed.101Auto-Increment for individual brightness registers only.

See T able3 for rollover values. For example, if MODE1register bit AI1=0 and AI0=1 and if the Control register = 10010010, then the registeraddressing sequence will be (in hex):20→21→…→26→0→1→2→…→19→02→03→…→19→02… as longas the master keeps sending or reading data.7.3Register definitionsTable 4.Register summary[1][2]D5D4D3D2D1D0Name Type FunctionRegister number(hex)00000000MODE1read/write Mode register 101000001MODE2read/write Mode register 202000010PWM0read/write brightness control LED0 03000011PWM1read/write brightness control LED1 04000100PWM2read/write brightness control LED2 05000101PWM3read/write brightness control LED3 06000110PWM4read/write brightness control LED4 07000111PWM5read/write brightness control LED5 08001000PWM6read/write brightness control LED6 09001001PWM7read/write brightness control LED70A001010PWM8read/write brightness control LED80B001011PWM9read/write brightness control LED90C001100PWM10read/write brightness control LED100D001101PWM11read/write brightness control LED110E001110PWM12read/write brightness control LED120F001111PWM13read/write brightness control LED13 10010000PWM14read/write brightness control LED14 11010001PWM15read/write brightness control LED15 12010010PWM16read/write brightness control LED16 13010011PWM17read/write brightness control LED17分销商库存信息:NXPPCA9626B,118PCA9626BS,518。
