Connected. Energy-friendly.Rev. 1.00 | 33.3.4 Matching Network for 2.4 GHzThe BRD4161A Radio Board incorporates a 2.4 GHz matching network which connects the 2.4 GHz TRX pin of the EFR32MG12 to the one on-board printed Inverted-F antenna. The component values were optimized for the 2.4 GHz band RF performace and current con-sumption with 19 dBm output power.For detailed description of the matching network, see Chapter 4.2.1 Description of the 2.4 GHz RF Matching.3.3.5 Inverted-F AntennaThe BRD4161A Radio Board includes a printed Inverted-F antenna (IFA) tuned to have close to 50 Ohm impedance at the 2.4 GHz band.For detailed description of the antenna see Chapter 4.5 Inverted-F Antenna.3.3.6 UFL ConnectorTo be able to perform conducted measurements, Silicon Labs added an UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.Note: By default the output of the matching network is connected to the printed Inverted-F antenna by a series component. It can be connected to the UFL connector as well through a series 0 Ohm resistor which is not mounted by default. For conducted measurements through the UFL connector the series component to the antenna should be removed and the 0 Ohm resistor should be mounted (see Chapter 4.2 Schematic of the RF Matching Network for further details).3.3.7 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors make up the EFR32MG Radio Board interface to the Wireless Starter Kit Mainboard. For more information on the pin mapping between the EFR32MG12P432F1024GL125 and the Radio Board Connector, refer to Chapter 2.2 Radio Board Connector Pin Associations.3.3.8 Capacitive Touch SliderThe touch slider (T2) utilizes the capacitive touch capability of the Capacitance Sense Module of the EFR32MG12. The slider interpo-lates 4 separate pads to find the exact position of a finger.The figure below shows the pin mapping of the touch slider to the Wireless SoC.Wireless SoCFigure 3.2.

RF Section4.1 IntroductionThis section gives a short introduction to the RF section of the BRD4161A.4.2 Schematic of the RF Matching NetworkThe schematic of the RF section of the BRD4161A Radio Board is shown in the following figure.2.4 GHz Matching 2.4 GHz RF OutputSelection & Inverted-F AntennaFigure 4.1. Schematic of the RF Section of the BRD4161A4.2.1 Description of the 2.4 GHz RF MatchingThe 2.4 GHz matching connects the 2G4RF_IOP pin to the on-board printed Inverted-F Antenna. The 2G4RF_ION pin is connected to ground. For higher output powers (13 dBm and above), besides the impedance matching circuitry, it is recommended to use additional harmonic filtering as well at the RF output. The targeted output power of the BRD4161A board is 19 dBm. Therefore, the RF output of the IC is connected to the antenna through a four-element impedance matching and harmonic filter circuitry.For conducted measurements the output of the matching network can also be connected to the UFL connector by removing the series R1 component between the antenna and the output of the matching and adding a 0 Ohm resistor to the R2 resistor position between the output of the matching and the UFL connector.4.3 RF Section Power SupplyOn the BRD4161A Radio Board the power supply pins of the RF section (RFVDD, PAVDD) are directly connected to the output of the on-chip DC-DC converter. This way, by default, the DC-DC converter provides 1.8 V for the entire RF section (for details, see the sche-matic of the BRD4161A).4.4 Bill of Materials for the 2.4 GHz MatchingThe Bill of Materials of the 2.4 GHz matching network of the BRD4161A Radio Board is shown in the following table.| Smart. Connected. Energy-friendly.Rev. 1.00 | 5Table 4.1. Bill of Materials for the BRD4161A 2.4GHz RF Matching Network4.5 Inverted-F AntennaThe BRD4161A Radio Board includes an on-board printed Inverted-F Antenna tuned for the 2.4 GHz band. Due to the design restric-tions of the Radio Board, the input of the antenna and the output of the matching network can't be placed directly next to each other. As a result, a 50 Ohm transmission line was necessary to connect them. With the actual line length the impedance of the antenna at the double-harmonic frequency is transformed closer to a "critical load impedance range" resulting in the radiated level of the harmonic increases.To reduce the harmonic radiation a tuning component was used between the matching network output and the antenna input. For the actual Radio Board design (with the actual transmission line length) a small value inductor was used (instead of the R1 resistor with value of 1.8 nH) to transform the impedance at the double-frequency harmonic away from the critical region while keeping the impe-dance at the funamental close to 50 Ohm. With this the suppression of the radiated double-frequency harmonic increases by approxi-mately 3-4 dB. The resulting impedance and reflection measured at the output of the matcing network are shown in the following figure. As it can be observed the impedance is close to 50 Ohm (the reflection is better than -10 dB) for the entire 2.4 GHz band.Figure 4.2. Impedance and Reflection of the Inverted-F Antenna of the BRD4161A Board Measured from the Matching Output Note: The same value and type of 1.8 nH inductor was used as the one in the matching network (L1). | Smart.

BRD4161A Bottom ViewMechanical DetailsRev. 1.00 | 7EMC Compliance 6. EMC Compliance6.1 IntroductionCompliance of the fundamental and harmonic levels is tested against the following standards:• 2.4 GHz:•ETSI EN 300-328•FCC 15.2476.2 EMC Regulations for 2.4 GHz6.2.1 ETSI EN 300-328 Emission Limits for the 2400-2483.5 MHz BandBased on ETSI EN 300-328 the allowed maximum fundamental power for the 2400-2483.5 MHz band is 20 dBm EIRP. For the unwan-ted emissions in the 1 GHz to 12.75 GHz domain the specified limit is -30 dBm EIRP.6.2.2 FCC15.247 Emission Limits for the 2400-2483.5 MHz BandFCC 15.247 allows conducted output power up to 1 Watt (30 dBm) in the 2400-2483.5 MHz band. For spurious emmissions the limit is -20 dBc based on either conducted or radiated measurement, if the emission is not in a restricted band. The restricted bands are speci-fied in FCC 15.205. In these bands the spurious emission levels must meet the levels set out in FCC 15.209. In the range from 960 MHz to the frequency of the 5th harmonic it is defined as 0.5 mV/m at 3 m distance (equals to -41.2 dBm in EIRP).Additionally, for spurious frequencies above 1 GHz, FCC 15.35 allows duty-cycle relaxation to the regulatory limits. For the EmberZNet PRO the relaxation is 3.6 dB. Therefore, the -41.2 dBm limit can be modified to -37.6 dBm.If operating in the 2400-2483.5 MHz band the 2nd, 3rd and 5th harmonics can fall into restricted bands. As a result, for those the -37.6 dBm limit should be applied. For the 4th harmonic the -20 dBc limit should be applied.6.2.3 Applied Emission Limits for the 2.4 GHz BandThe above ETSI limits are applied both for conducted and radiated measurements.The FCC restricted band limits are radiated limits only. Besides that, Silicon Labs applies those to the conducted spectrum i.e., it is assumed that, in case of a custom board, an antenna is used which has 0 dB gain at the fundamental and the harmonic frequencies. In that theoretical case, based on the conducted measurement, the compliance with the radiated limits can be estimated.The overall applied limits are shown in the table below.Table 6.1. Applied Limits for Spurious Emissions for the 2.4 GHz Band | Smart. Connected. Energy-friendly.Rev. 1.00 | 87. RF Performance7.1 Conducted Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V.7.1.1 Conducted Measurements in the 2.4 GHz bandThe BRD4161A board was connected directly to a Spectrum Analyzer through its UFL connector (the R1 component was removed and a 0 Ohm resistor was soldered to the R2 resistor position). During measurements, the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4161A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 19 dBm.The typical output spectrum is shown in the following figure.Figure 7.1. Typical Output Spectrum of the BRD4161AAs it can be observed, the fundamental is slightly lower than 19 dBm limit and the strongest unwanted emission is the double-frequency harmonic and it is under the -37.6 dBm applied limit.Note: The conducted measurement is performed by connecting the on-board UFL connector to a Spectrum Analyzer through an SMA Conversion Adapter (P/N: HRMJ-U.FLP(40)). This connection itself introduces approximately 0.3 dB insertion loss.RF PerformanceRev. 1.00 | 97.2 Radiated Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V. The radiated power was measured in an antenna chamber by rotating the DUT 360degrees with horizontal and vertical reference antenna polarizations in the XY , XZ and YZ cuts. The measurement axes are shown inthe figure below.Figure 7.2. DUT: Radio Board with the Wireless Starter Kit Mainboard (Illustration)Note: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also the radi-ated power levels may change depending on the actual application (PCB size, used antenna, and so on). Therefore, the absolute levels and margins of the final application are recommended to be verified in a licensed EMC testhouse.7.2.1 Radiated Measurements in the 2.4 GHz bandFor the transmitter antenna the on-board printed Inverted-F antenna of the BRD4161A board was used (the R1 component was moun-ted). During measurements, the board was attached to a Wireless Starter Kit Mainboard (BRD4001 (Rev. A02) ) which was supplied through USB. During the measurements the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4161A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 19 dBm based on the conducted measurement.The results are shown in the table below.Table 7.1. Maximums of the measured radiated powers in EIRP [dBm]As it can be observed, thanks to the high gain of the Inverted-F antenna, the level of the fundamental is higher than 19 dBm. The stron-gest harmonic is the double-frequency one and thanks to the additional suppression provided by the instead of the R1 resistor its level is under -50 dBm.RF PerformanceEMC Compliance Recommendations 8. EMC Compliance Recommendations8.1 Recommendations for 2.4 GHz ETSI EN 300-328 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4161A Mighty Gecko Radio Board complies with the 20 dBm limit of the ETSI EN 300-328 in case of the conducted measurement but due to the high antenna gain the radiated power is higher than the limit by 2 dB. In order to comply, the output power should be reduced (with different antennas, depending on the gain of the used antenna, the necessary reduction can be different). The harmonic emissions are under the -30 dBm limit. Although the BRD4161A Radio Board has an option for mounting a shielding can, that is not required for the compliance.8.2 Recommendations for 2.4 GHz FCC 15.247 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4161A Mighty Gecko Radio Board complies with the 30 dBm limit of the FCC 15.247. The harmonic emissions are under the -37.6 dBm applied limit both in case of the conducted and the radiated measurements. Although the BRD4161A Radio Board has an option for mounting a shielding can, that is not required for the compliance.Document Revision History 9. Document Revision HistoryTable 9.1.

咱先来说说快充的需求是咋来的。
你想啊,以前咱们手机充电那叫一个慢,充个电等得花儿都谢了。
所以呢,快充技术就应运而生啦。
但是呢,不同的设备它能接受的充电功率是不一样的,就像有的人只能吃一小碗饭,你给一大盆就不行了。
这时候快充识别芯片就闪亮登场啦。
这个芯片啊,就像是一个超级聪明的小门卫。
它住在充电线或者手机的充电接口附近呢。
当你把充电器插到手机上的时候,电流就像一群小蚂蚁一样跑过来啦。

In sleep mode, the H-bridge FETs are disabledPOWER SUPPLY RECOMMENDATIONSHaving appropriate local bulk capacitance is an important factor in motor-drive system design. It is generally beneficial to have more bulk capacitance.The amount of local bulk capacitor needed depends on the following factors ,∙The highest current required by the motor system.∙The power-supply capacitance and ability to source current∙The amount of parasitic inductance between the power supply and motor system∙The acceptable voltage ripple∙The type of motor used (brushed dc, brushless dc, stepper)∙The motor braking methodThe inductance between the power supply and motor drive system limits the rate at which current can change from the power supply. If the local bulk capacitance is too small, the system responds to excessive current demands or dumps from the motor with a change in voltage. When adequate bulk capacitance is used, the motor voltage remains stable and high current can be quickly supplied.The voltage rating for bulk capacitors should be higher than the operating voltage, to provide margin for cases whenFigure 3. Motor Driver System with External Power SupplyPCB LAYOUTThe VM and VCC should be bypassed to GND using low-ESR ceramic capacitors with recommended value of 0.1µF.

PT2262,2272无线发射接收芯片这是一种目前用途非常广泛的200米四键遥控模块,常用于报警器设防、车库门遥控、摩托车、汽车的防盗报警等,这类用途要求遥控器的遥控距离并不远,一般50米足够了,但要求:遥控模块价格低廉,发射机手柄体积小巧、外观精致,耗电尽可能省,工作稳定可靠。
这里提供的发射机体积非常小巧,体积只有58x38x8毫米,采用桃木花纹的优质塑料外壳,带保险盖,防止误碰按键,天线拉出时长13厘米,遥控器只有20克。
上图为发射器外形,面板上有A、B、C、D四位操纵按键及一个发射指示灯。
发射机内部采用进口声表谐振器稳频,频率一致性非常好,稳定度极高,工作频率315MHZ频率稳定度优于10-5,使用中无需调整频点,特别适合多发一收等无线电遥控系统使用,而目前市场上的无线电遥控模块一般仍采用LC振荡器,稳定度及一致性较差,即使采用高品质微调电容,温度变化及震动也很难保证已调试好的频点不会发生偏移,造成发射距离缩短。
接收模块采用SMD贴片工艺制造生产,为超再生接收方式,它内含放大整形及解码电路,使用极为方便。
1、天线输入端有选频电路,而不依赖1/4波长天线的选频作用,控制距离较近时可以剪短甚至去掉外接天线92、接收电路自身辐射极小,加上电路模块背面网状接地铜箔的屏蔽作用,可以减少自身振荡的泄漏和外界干扰信号的侵入。
3、接收机采用高精度带骨架的铜芯电感将频率调整到315M后封固,这与采用可调电容调整接收频率的电路相比,温度、湿度稳定性及抗机械振动性能都有极大改善。
可调电容调整精度较低,只有3/4圈的调整范围,而可调电感可以做到多圈调整。
可调电容调整完毕后无法封固,因为无论导体还是绝缘体,各种介质的靠近或侵入都会使电容的容量发生变化,进而影响接收频率。
另外未经封固的可调电容在受到振动时定片和动片之间发生位移;温度变化时热胀冷缩会使定片和动片间距离改变;湿度变化因介质变化改变容量;长期工作在潮湿环境中还会因定片和动片的氧化改变容量,这些都会严重影响接收频率的稳定性,而采用可调电感就可解决这些问题,因为电感可以在调整完毕后进行封固,绝缘体封固剂不会使电感量发生变化,而且由于采用贴片工艺,所以即使强烈震动也不必担心接收频点漂移,接收电路的接收带宽约500KHz,产品出厂时已经将中心频率调整在315MHz,接收芯片上的微调电感约有5MHz频率的可调范围,使用时不要轻易变动,以免影响性能。
BDR2L00Half-Bridge DriverDESCRIPTIONThe BDR2L00 is a single Phase MOSFET gate driver optimized to drive the gates of both high-side and low-side power MOSFETs.FEATURES∙ Drive two N-MOSFETs∙ High-Frequency operation (Up to 1MHz) ∙ PWM input capable of 3.3V and 5V ∙ Fast output rise timeAPPLICATION CIRCUIT SOP8/DFN8:PIN CONFIGURATIONABSOLUTE MAXIMUM RATINGSStresses exceeding the absolute maximum ratings may damage the device or make the function abnormal. All the voltage parameters are absolute voltages referenced to IC PGND unless otherwise stated in the table.ELECTRICAL CHARACTERISTICSAPPLICATION INFORMATIONTheory of OperationThe BDR2L00 is an integrated driver and boot diode module designed for N+N half bridge driver. A single PWM input signal is all that is required to properly drive the high−side and low−side MOSFETs.Low−Side DriverThe low-side driver is designed to drive a ground−referenced low R DS(on)N−Channel MOSFET. The voltage rail for the low−side driver is internally connected to VCC and GND.High−Side DriverThe high-side driver is designed to drive a floating low RDS(ON) N−channel MOSFET. The gate voltage for the high side driver is developed by a bootstrap circuit referenced to Switch Node (PHASE) pin.The bootstrap circuit is comprised of the internal diode and an external bootstrap capacitor. When the BDR2L00 is starting up, the PHASE pin is at ground, so the bootstrap capacitor will charge up to VCC through the bootstrap diode. When the PWM input goes high, the high−side driver will begin to turn on the high−side MOSFET using the stored charge of the bootstrap capacitor. As the high−side MOSFET turns on, the PHASE pin will rise. When the high−side MOSFET is fully on, the switch node will be at 12V, and the BST pin will be at 5V plus the charge of the bootstrap capacitor (approaching 17V).The bootstrap capacitor is recharged when the switch node goes low during the next cycle.Safety Timer and Overlap Protection CircuitIt is very important that MOSFETs in a synchronous buck regulator do not both conduct at the same time. Excessive shoot−through or cross conduction can damage the MOSFETs, and even a small amount of cross conduction will cause a decrease in the power conversion efficiency.The BDR2L00 prevents cross conduction by monitoring the status of the MOSFETs and applying the appropriate amount of “dead−time” or the time between the turn off of one MOSFET and the turn on of the other MOSFET.When the PWM input pin goes high, the gate of the low−side MOSFET will go low after a propagation delay. The time it takes for the low−side MOSFET to turn off is dependent on the total charge on the low−side MOSFET gate. Likewise, when the PWM input pin goes low, the gate of the high−side MOSFET will go low after the propagation delay. The time to turn off the high−side MOSFET is dependent on the total gate charge of the high−side MOSFET.Enable (Only for DFN8)If EN pin is low level, whatever the PWM pin is high or low, all circuits are shutdown. If EN pin is high level, the outputs are controlled by PWM pin.Thermal ShutdownIf the driver temperature exceeds 170°C, the part will enter thermal shutdown and turn off both MOSFETs. Once the temperature falls below 150°C, the part will resume normal operation.Power Supply DecouplingThe BDR2L00 can source and sink relatively large current to the gate pins of the MOSFETs. In order to maintain a constant and stable supply voltage (VCC) a low ESR capacitor should be placed near the power and ground pins. A 2.2uF to 10uF multilayer ceramic capacitor (MLCC) is usually sufficient.Bootstrap CircuitThe bootstrap circuit uses a charge storage capacitor (C BST). The bootstrap capacitor must have a voltage rating that is able to withstand twice the maximum supply voltage. A minimum 16 V rating is recommended. A bootstrap capacitance greater than 680nF and a minimum 16V rating is recommended. A good quality ceramic capacitor should be used.PACKAGE INFORMATION 8 PINS, SOP, 150MIL8-PINS, DFN, 3X3。
