PROTECTION PRODUCTS Applications Information
Device Connection for Protection of Four Data Lines
The SMDAxxC series devices are designed to protect up to four data lines. The devices are connected as follows:
l The SMDAxxC are bidirectional devices and are designed for use on lines where the normal operating voltage is above and below ground. Pins 1, 2, 3, and 4 are connected to the protected lines. Pins 5, 6, 7, and 8 are connected to ground. Since the device is electrically symmetrical, these connections may be reversed. The ground connections should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces.

将常用的多项功能集成到一片8脚封装的小芯片内，与采用分立元件或单一功能芯片组合的电路相比，大大减小了系统电路的复杂性和元器件的数量，显著提高了系统可靠性和精确度。

该系列产品采用3种不同的8脚封装形式：DIP、SO和mMAX。

主要应用于：微处理器和微控制器系统；嵌入式控制器系统；电池供电系统；智能仪器仪表；通信系统；寻呼机；蜂窝移动电话机；手持设备；个人数字助理(PDA)；电脑电话机和无绳电话机等等。

功能说明RESET/RESET操作复位信号用于启动或者重新启动MPU/MCU，令其进入或者返回到预知的循环程序并顺序执行。

一旦MPU/MCU处于未知状态，比如程序“跑飞”或进入死循环，就需要将系统复位。

对于MAX705和MAX706而言，在上电期间只要Vcc大于1.0V，就能保证输出电压不高于0.4V的低电平。

在Vcc上升期间RESET维持低电平直到电源电压升至复位门限(4.65V或4.40V)以上。

在超过此门限后，内部定时器大约再维持200ms后释放RESET，使其返回高电平。

无论何时只要电源电压降低到复位门限以下(即电源跌落)，RESET引脚就会变低。

Please contact Oki Electric Industry Co., Ltd. for detailed information.1Oki Semiconductor ML7050LADESCRIPTION OF INTERNAL BLOCKS• Transmit filter (Gaussian filter):The input data is converted into a frequency modulation signal by a filter with Gaussian characteristics and is sent to the VCO.• Frequency control section (VCO, PLL, Loop Filter, AMP and SW):Generates a frequency in the 2.4 GHz to 2.5 GHz band (ISM band). During transmission, the VCO oscillator frequency is modulated by the modulation signal output by the Gaussian filter. The PLL frequency is controlled by the signals PLL_DATA, PLL_CLK, and PLL_LE. The switch SW (for Local) distributes the oscillator output to the transmitter circuit and the receiver circuit depending on the control signal (TX_POW/RX_POW).• Power amplifier (PA):This is the power amplifier for the transmitter.• Transmit/Receive selection switch (SW for Ant)Depending on the control signal (TX_POW/RX_POW), this switch feeds the output of the power amplifier to the antenna during transmission. During reception, the received signal of the antenna is fed to the LNA.• Reception amplifier (LNA):This amplifies the weak RF received signal from the antenna.• Image Rejection Mixer (IRM):Converts the output signal from the LNA (2.4 to 2.5 GHz) into an intermediate frequency and also eliminates the image frequency component.• IF Band pass filter (IF BPF):Removes the signal of the nearby bands.• Limiting amplifier:Amplifies the signal converted into the intermediate frequency up to a specific amplitude.• Demodulator (DEMOD):The received signal is demodulated using the delay detector circuit.• Filter tuning (Gm-C Tuning):The reference clock is compared with the oscillator frequency inside the tuning circuit, and the frequency characteristics of the Gm-C filter is adjusted automatically.1Oki Semiconductor ML7050LA PLL METHODOLOGY1Oki SemiconductorML7050LAPLL Computation MethodFvcoFosc (0 <= A<=31)MxN+AR(M × N + A denotes (M - A) × 32 + A × 33)R:Reference counter set value N:Programmable counter set value A:Swallow counter set valuePLL Reference CounterFreq R R(Bin)(MHz)(Dec)R4R3R2R1R055001016600110770011188010009901001101001010111101011121201100131301101141401110151501111161610000171710001181810010191910011202011Programmable Counter and Swallow CounterF.step 1 MHz M32 div(RX PLL Frequency) = (TX PLL Frequency) – 2MHz* In receive mode, PLL generates local frequency for IRM.

The ML70511LA baseband IC controls the ML7050LA frequency selection, tuning characteristics, and control functions through writing to internal registers. ML7050LA can then read-back the register information to ML70511LA insuring proper modes of operation. The communication between the devices occurs on Oki’s proprietary, low pin count serial interface. The connection between a host controller or processor and the baseband device is implemented via USB (version 1.1) or UART.Power SupplyThe analog power supply (V DD ) voltage is connected to pins serving each analog functional blocks (Vdd_PA,Vdd_LNA, Vdd_VCO, Vdd_PLL, Vdd_IF, Vdd_IRM and Vdd_IRM_LO). A separate digital power supply voltage is required by the digital section. Each of the analog power supply voltage should be supplied from regulated voltage source and should be low-frequency de-coupled by external blocking capacitors.GroundIn order to minimize electrical noise and other interference, the ground plane should be distributed with low impedance characteristics including underneath the ML7050LA. Connect all GND pins to the ground plane.1Oki Semiconductor ML7050LA PACKAGE DIMENSIONS (48-PIN BGA)(Unit: mm)1Oki Semiconductor ML7050LA NOTICE1.The information contained herein can change without notice owing to product and/or technical improvements.Before using the product, please make sure that the information being referred to is up-to-date.2.The outline of action and examples for application circuits described herein have been chosen as an explanationfor the standard action and performance of the product.

1 W BTL mono audio amplifier
FUNCTIONAL DESCRIPTION
TDA7052
The TDA7052 is a mono output amplifier designed for battery-fed portable audio applications, such as tape recorders and radios. The gain is fixed internally at 40 dB. A large number of tape recorders and radios are still designed for mono sound, plus a space-saving trend by reduction of the number of battery cells. This means a decrease in supply voltage which results in an reduction of output power. To compensate for this reduction, the TDA7052 uses the Bridge-Tied-Load principle (BTL) which can deliver an output power of 1,2 W (THD = 10%) into an 8 Ω load with a power supply of 6 V. The load can be short-circuited at each signal excursion.

SLA7052M中文资料Data Sheet28210.1B* UNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVERCombining low-power CMOS logic with high-current, high-voltagepower FET outputs, the SLA7052M translator/driver provides completecontrol and drive for a two-phase unipolar stepper motor with internalfixed off time, pulse-width modulation (PWM) control of the outputcurrent in a power multi-chip module (PMCM?).The CMOS logic section provides the sequencing logic, direction,full/half-step control, synchronous/asynchronous PWM operation, anda “sleep” function. The minimum CLOCK input is an idealapplications where a complex μP is unavailable or overburdened. TTLor LSTTL may require the use of appropriate pull-up resistors to ensurea proper input-logic high. For PWM current control, the maximumoutput current is determined by the user’s selection of a referencevoltage and sensing resistor. The NMOS outputs are capable of sinkingup to 3 A and withstanding 46 V in the off state. Ground-clamp andflyback diodes provide protection against inductive transients. Specialpower-up sequencing is not required.Full-step (2 phase) and half-step operation are externally selectable.Two-phase drive energizes two adjacent phases in each detent position(AB-BC-CD-DA). This sequence mode offers an improved torque-speed product, greater detent torque, and is less susceptable to motorresonance. Half-step excitation alternates between the one-phase andtwo-phase modes (A-AB-B-BC-C-CD D-DA), providing an eight-stepsequence.The SLA7052M is supplied in an 18-pin single in-line power-package with leads formed for vertical mounting (suffix LF871) orhorizontal mounting (suffix LF872). The tab is at ground potential andneeds no insulation. For high-current or high-frequency applications,external heat sinking may be required.

The SLA7052M is a complete stepper-motor driver with built-in translator for easy operation with minimal control lines. It is designed to operate unipolar stepper motors in full-step or half-step modes. The current in each pair of outputs, all n-channel MOSFETs, is regulated with internal fixed off-time pulse-width modulated (PWM) control circuitry.When a step command signal occurs on the clock input the translator automatically sequences to the next step.Clock (step) input. A low-to-high transition on the clock input sequences thetranslator and advances the motor one increment. The hold state is done by stopping the CLOCK input regardless of the input level Full/half-step select. This logic-level input sets the translator step mode. A logic low is two-phase, full step; a logic high is half step. Changes to this input do not take effect until the rising edge of the clock input.CW/CCW (direction) input. This logic-level input sets the translator step direction. Changes to this input do not take effect until the rising edge of the clock input.Internal PWM current control. Each pair of outputs is controlled by a fixed off-time PWM current-control circuit that limits the load current to a desired value (I TRIP ).Initially, an output is enabled and current flows through the motor winding and R S . When the voltage across the current-sense resistor equals the reference voltage, the current-sense comparator resets the PWM latch, which turns off the driver for the fixed off time during which the load inductance causes the current to recirculate for the off time period. The driver is then re-enabled and the cycle repeats.Synchronous operation mode. This function pre-vents occasional motor noise during a “hold” state, which normally results from asynchronous PWM operation of both motor phases.A logic high at the SYNC input is synchronous operation; a logic low is asynchronous operation. The use of synchronous operation during normal stepping is not recommended because it produces less motor torque and can cause motor vibration due to stair-case current.Sleep mode. Applying a voltage greater than 2 V to the REF pin disables the outputs and puts the motor in a free state (coast). This function is used to minimize power consumption when notin use. It disables much of the internal circuitry including the output MOSFETs and regulator. When coming out of sleep mode, wa it 100 μs before issuing a step command to allow the internal circuitry to stabilize.SLA7052MUNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER6Mo t orD ri v erApplications informationLayout.The printed wirting board should use a heavy groundplane.For optimum electrical and thermal performance, thedriver should be soldered directly into the board.The driver supply terminal, VBB, should be decoupledwith an electrolytic capacitor placed as close to the device as possible.To avoid problems due to capacitive coupling of thehigh dv/dt switching transients, route the high-level, output traces away from the sensitive, low-level logic traces. Always drive the logic inputs with a low source impedance to increase noise immunity.Grounding. A star ground system located close to the driver is recommended. The logic supply return and the driver supply return should be connected together at only a single point — the star ground.Logic supply voltage, VDD. Transients at this terminalshould be held to less than 0.5 V to avoid malfunctioning operation. Both VBBand VDDmay be turned on or offseparately.Logic inputs. Unused logic inputs (CW/CCW, FULL/ HALF, or SYNC) must be connected to either ground orthe logic supply voltage.Current sensing. T o minimize inaccuracies caused by ground-trace IR drops in sensing the output current level, the current-sense resistor, RS, should have an independentground return to the star ground of the device. This path should be as short as possible. For low-value sense resistors, the IR drops in the printed wiring board sense resistor’s traces can be significant and should be taken into account. The use of sockets should be avoided as they can introduce variation in RSdue to their contact resistance.PWM current control. The maximum value of current limiting (ITRIP) is set by the selection of RSand the voltageat the REF input with a transconductance function ap- proximated by:ITRIP= VREF/RSThe required VREFshould not be less than 0.1 V. If it is,RSshould be increased for a proportionate increase inVREF.Typical applicationSLA7052MUNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER7M o t o r Dr i v e r Applications Information (cont’d)Continuous Discontinuous mode modeNormalized FET on resistanceSync. signal generatorReference voltage. In the Typical Application shown,resistors R 1 and R 2 set the reference voltage as:V REF = (V DD x R 2)/(R 1 + R 2)The trimming of R 2 allows for the resistor tolerances and REF input current. The sum of R 1+R 2 should be less than 50 k ? to minimize the effect of I REF .Minimum output current. The SLA7052M uses fixed off-time PWM current control. Due to internal logic and switching delays, the actual load current peak will be slightly higher than the calculated I TRIP value (especially for low-inductance loads). These delays, plus the mini-mum recommended V REF , limit the minimum value the current-control circuitry can regulate. An application with this device should maintain continuous PWM control in order to obtain optimum torque out of the motor. The boundary of the load current (I O(min)) between continuous and discontinuous operation is:I O(min) = [(V M + V SD )/R m ] x [(1/e t off /[R m x L m ]) -1]where V M = load supply voltageV F = body diode forward voltage R m = motor winding resistance t off = PWM off timeL m = motor winding inductanceTo produce zero current in a motor, the REF input should be pulled above 2 V, turning off all drivers.Synchronous operation mode. If an external signal is not available to control the synchronous operationmode, a simple circuit can keep the SYNC input low while the CLOCK input is active; the SYNC input will go high (synchronous operation) when the CLOCK input stays low (“hold”). The RC time constant determines the sync trransition timing.Temperature effects on FET outputs. Analyzing safe, reliable operation includes a concern for the relation-ship of NMOS on resistance to junction temperature.Device package power calculations must include the increase in on resistance (producing higher on voltages)caused by increased operating junction temperatures.

There is a surge voltage expected when the output MOSFET turns off, and this voltage may exceed the MOSFET breakdown voltage (V (BR)DS ). However, the MOSFETs are avalanche type and as long as the energy (E (AV)), which is imposed on the MOSFET by the surge voltage, is less than the maximum allowable value, it is considered to be within its safe operating area. Note that the maximum allowable ava-lanche energy is reduced as a function of temperature.In application, the avalanche energy (E (AV)) dissipated by the MOSFET is approximated asE (AV) = V DS(AV) x 1/2 x I D x tOutput circuit for avalanche energycalculationsSLA7052MUNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER9M o t o r Dr i v e r Terminal listTerminal Pin Name Terminal Description 1OUT A Driver output for phase A 2NU Not usable3OUT A \Driver output for phase A\4GATE A Phase AMOSFET Gate 5V DD Logic power supply 6SENSE A Phase A current sense 7CLOCK Step clock input8SYNC Synchronous PWM control input 9REF Current set & “sleep” control 10GND Supply negative return11CW/CCWForward/reverse logic control input12FULL/HALF Full step/half step logic control input 13SENSE B Phase B current sense 14V BB Driver power supply 15GATE B Phase B MOSFET Gate 16OUT B \Driver output for phase B\17NU Not usable18OUT BDriver output for phase BThe products described herein are manufactured in Japan by Sanken Electric Co., Ltd. for sale by Allegro MicroSystems, Inc.Sanken and Allegro reserve the right to make, from time to time,such departures from the detail specifications as may be required to permit improvements in the performance, reliability, ormanufacturability of its products.
