S8261和DW01-8205A主流锂电池保护板原理图说明

S8261和DW01-8205A主流锂电池保护板原理图说明锂电池保护板的主要参数锂电池保护板主要由保护IC和MOS管构成（1）保护IC主要参数1) 封装2) 过充电压3) 过充释放电压4) 过放电压5) 过放释放电压6) 耐压(2) MOSFET主要参数1) N沟、P沟2) 内阻3) 封装（TSSOP8 <简称薄片> 、SOP8<简称厚片>、SOT23-6等）4) 耐电流5) 耐电压6) 内部是否连通锂电池保护板的工作原理锂电池保护板根据使用IC,电压等不同而电路及参数有所不同,保护板有两个核心部件：一块保护IC，它是由精确的比较器来获得可靠的保护参数；另外是MOSFET串在主充放电回路中担当高速开关，执行保护动作。

下面以DW01 配MOS 管8205A进行讲解:激活保护板的方法：当保护板P+、P-没有输出处于保护状态，可以短路B-、P-来激活保护板，这时，Dout、Cout均会处于低电平（保护IC此两端口是高电平保护，低电平常态）状态打开两个MOS开关。

1.锂电池保护板其正常工作过程为:当电芯电压在2.5V至4.3V之间时，DW01 的第1脚、第3脚均输出高电平(等于供电电压)，第二脚电压为0V。

此时DW01 的第1脚、第3脚电压将分别加到8205A的第5、4脚，8205A内的两个电子开关因其G极接到来自DW01 的电压，故均处于导通状态，即两个电子开关均处于开状态。

此时电芯的负极与保护板的P-端相当于直接连通，保护板有电压输出。

2.保护板过放电保护控制原理:当电芯通过外接的负载进行放电时,电芯的电压将慢慢降低,同时DW01 内部将通过R1电阻实时监测电芯电压,当电芯电压下降到约2.3V时DW01 将认为电芯电压已处于过放电电压状态，便立即断开第1脚的输出电压，使第1脚电压变为0V，8205A内的开关管因第5脚无电压而关闭。

此时电芯的B-与保护板的P-之间处于断开状态。

It also achieves a constant slew rate, bandwidth and settling time over its entire specified temperature range. The AD826 (Figure 35) consists of a degenerated NPN differen-tial pair driving matched PNPs in a folded-cascode gain stage. The output buffer stage employs emitter followers in a class AB amplifier which delivers the necessary current to the load while maintaining low levels of distortion.–INNULL 1NULL 8S–VSFigure 35. Simplified SchematicThe capacitor, C F, in the output stage mitigates the effect of capacitive loads. With low capacitive loads, the gain from the compensation node to the output is very close to unity. In this case, C F is bootstrapped and does not contribute to the overall compensation capacitance of the device. As the capacitive load is increased, a pole is formed with the output impedance of the output stage. This reduces the gain, and therefore, C F is incompletely bootstrapped. Effectively, some fraction of C F contributes to the overall compensation capacitance, reducing the unity gain bandwidth. As the load capacitance is further increased, the bandwidth continues to fall, maintaining the stability of the amplifier.INPUT CONSIDERATIONSAn input protection resistor (R IN in Figure 25) is required in circuits where the input to the AD826 will be subjected to transient or continuous overload voltages exceeding the ±6 V maximum differential limit. This resistor provides protection for the input transistors by limiting their maximum base current. For high performance circuits, it is recommended that a “bal-ancing” resistor be used to reduce the offset errors caused by bias current flowing through the input and feedback resistors. The balancing resistor equals the parallel combination of R IN and R F and thus provides a matched impedance at each input terminal. The offset voltage error will then be reduced by more than an order of magnitude.APPLYING THE AD826The AD826 is a breakthrough dual amp that delivers precision and speed at low cost with low power consumption. The AD826 offers excellent static and dynamic matching characteristics, combined with the ability to drive heavy resistive and capacitive loads.As with all high frequency circuits, care should be taken to main-tain overall device performance as well as their matching. The following items are presented as general design considerations. Circuit Board LayoutInput and output runs should be laid out so as to physically isolate them from remaining runs. In addition, the feedback resistor of each amplifier should be placed away from the feedback resistor of the other amplifier, since this greatly reduces inter-amp coupling.Choosing Feedback and Gain ResistorsIn order to prevent the stray capacitance present at each amplifier’s summing junction from limiting its performance, the feedback resistors should be ≤ 1 kΩ. Since the summing junction capaci-tance may cause peaking, a small capacitor (1 pF–5pF) may be paralleled with R F to neutralize this effect. Finally, sockets should be avoided, because of their tendency to increase interlead capacitance.Power Supply BypassingProper power supply decoupling is critical to preserve the integrity of high frequency signals. In carefully laid out designs, decoupling capacitors should be placed in close proximity to the supply pins, while their lead lengths should be kept to a mini-mum. These measures greatly reduce undesired inductive effects on the amplifier’s response.Though two 0.1µF capacitors will typically be effective in decoupling the supplies, several capacitors of different values can be paralleled to cover a wider frequency range.AD826؎SINGLE SUPPLY OPERATIONAn exciting feature of the AD826 is its ability to perform well in a single supply configuration (see Figure 37). The AD826 is ideally suited for applications that require low power dissipation and high output current and those which need to drive large capacitive loads, such as high speed buffering and instrumentation. Referring to Figure 36, careful consideration should be given to the proper selection of component values. The choices for this particular circuit are: (R1 + R3)ʈR2 combine with C1 to form a low frequency corner of approximately 30 Hz.OUT0.1VFigure 36. Single Supply Amplifier Configuration R3 and C2 reduce the effect of the power supply changes on the output by low-pass filtering with a corner at12πR3C2.The values for R L and C L were chosen to demonstrate the AD826’s exceptional output drive capability. In this configura-tion, the output is centered around 2.5 V. In order to eliminate the static dc current associated with this level, C3 was inserted in series with R L.Figure 37.Single Supply Pulse Response, G = +1,R L = 150Ω, C L = 200 pFPARALLEL AMPS PROVIDE 100 mA TO LOADBy taking advantage of the superior matching characteristics ofthe AD826, enhanced performance can easily be achieved byemploying the circuit in Figure 38. Here, two identical cells areparalleled to obtain even higher load driving capability than thatof a single amplifier (100 mA min guaranteed). R1 and R2 areincluded to limit current flow between amplifier outputs thatwould arise in the presence of any residual mismatch.LFigure 38.Parallel Amp ConfigurationAD826SINGLE-ENDED TO DIFFERENTIAL LINE DRIVEROutstanding CMRR (> 80 dB @ 5 MHz), high bandwidth, wide supply voltage range, and the ability to drive heavy loads, make the AD826 an ideal choice for many line driving applications.In this application, the AD830 high speed video difference amp serves as the differential line receiver on the end of a back terminated, 50 ft., twisted-pair transmission line (see Figure 40).The overall system is configured in a gain of +1 and has a –3 dB bandwidth of 14 MHz. Figure 39 is the pulse response with a 2 V p-p, 1 MHz signal input.Figure 39.Pulse ResponseFigure 40.Differential Line DriverLOW DISTORTION LINE DRIVERThe AD826 can quickly be turned into a powerful, low distor-tion line driver (see Figure 41). In this arrangement the AD826can comfortably drive a 75Ω back-terminated cable, with a 5MHz, 2 V p-p input; all of this while achieving the harmonic distortion performance outlined in the following table.Configuration 2nd Harmonic 1.No Load –78.5 dBm 2.150 Ω R L Only –63.8 dBm 3.150Ω R L 7.5Ω R C–70.4 dBmIn this application one half of the AD826 operates at a gain of 2.1 and supplies the current to the load, while the other pro-vides the overall system gain of 2. This is important for two reasons: the first is to keep the bandwidth of both amplifiers the same, and the second is to preserve the AD826’s ability to oper-ate from low supply voltages. R C varies with the load and must be chosen to satisfy the following equation:R C = MR Lwhere M is defined by [(M+ 1) G S = G D ] and G D = Driver ’s Gain,Figure 41.Low Distortion AmplifierAD826HIGH PERFORMANCE ADC BUFFERFigure 42 is a schematic of a 12-bit high speed analog-to-digital converter. The AD826 dual op amp takes a single ended input and drives the AD872 A/D converter differentially, thus reduc-ing 2nd harmonic distortion. Figure 43 is a FFT of a 1MHz input, sampled at 10 MHz with a THD of –78 dB. The AD826can be used to amplify low level signals so that the entire range of the converter is used. The ability of the AD826 to perform on a ±5 volt supply or even with a single 5 volts combined with its rapid settling time and ability to deliver high current to compli-cated loads make it a very good flash A/D converter buffer as well as a very useful general purpose building block.V Figure 42.A Differential Input Buffer for High Bandwidth ADCsFigure 43.FFT, Buffered A/D ConverterAD826OUTLINE DIMENSIONSDimensions shown in inches and (mm).8-Lead Plastic Mini-DIP (N) Package8-Lead SO (R) Package45؇All brand or product names mentioned are trademarks or registered trademarks of their respective holders.C 1807a –0–6/00 (r e v .

If low level is detected, enter UART configuration mode. Exit the mode if high level is detected5.Function5.1. Function DescriptionCH9121 is a chip for transparent transmission between network and UART, and realizes bidirectional transparent transmission of serial data and network data. It supports 4 working modes (TCP CLEINT/SERVER, UDP CLIENT/SERVER), and the serial baud rate supported ranges from 300bps to 921600bps. Before use, the network parameters and UART parameters of the chip shall be configured by upper computer software NetModuleConfig.exe or serial commands. After the configuration is completed, CH9121 will save the configuration parameters to the internal storage space. And after the chip is reset, CH9121 will work according to the saved configuration value.The basic parameters of CH9121 include: name, MAC address display, dynamic access IP address setting, manual IP address setting (including CH9121 IP address, subnet mask, default gateway), and UART negotiation configuration.The name is mainly for the convenience of CH9121 module management within the LAN, with the length of not more than 20 bytes. The MAC address field shows the MAC address of the currently selectedmodule. There are two ways for CH9121 to set network parameters. 1) DHCP, that is, it automatically obtains network parameters from the gateway device with DHCP SERVER function; 2) manual setting. UART negotiation configuration function is to enter serial configuration mode by handshaking through the UART, which is disabled by default.CH9121 port parameters include: network mode, local port, target IP/domain name, destination port, serial baud rate/data bit/stop bit/parity check bit, network cable disconnection processing, RX packet length, RX packet timeout interval, network connection operation.The network mode (TCP SERVER/CLIENT, UDP SERVER/CLIENT), destination IP address, and local/destination port are the basic parameters of network communication. The destination IP address can also be accessed by domain name. The serial baud rate ranges from 300bps to 921600bps (the baud rate error of the serial port transmitting signal is less than 0.3%, and the allowable baud rate error of the serial port receiving signal is not less than 2%). It supports 5/6/7/8 data bits, 1/2 stop bits, odd/even/no parity check, blank 0, and mark 1 check mode. The network cable disconnection processing means that when the network cable is disconnected, CH9121 actively closes the connection or does not take any action. The length range of RX packet is 1-1024, which means that when the length of CH9121 UART receiving data reaches the set length, CH9121 will immediately packet the serial data and send it out via network. The timeout time setting range is 0-200, and the timeout unit is about 5ms. For example, when the timeout is 1, the data length of the serial port receiving buffer does not reach the length of the RX packet, and the serial port does not receive a new one in more than 5ms, the serial port timeout will occur. After the serial port timeout occurs, CH9121 will send the data received by the serial port over the network. When the timeout time is set to 0, the internal hardware timeout mechanism will be enabled (no new data is received after 4 data times), which is suitable for occasions where real-time requirements are high and large quantities of data are sent and received. Clear serial port buffer setting refers to how the data received by the serial port is processed before the network connection is established, the data is cleared (discarded) or retained after TCP connection.5.2. Default ConfigurationWhen CH9121 leaves factory, port 2 is closed and port 1 works in TCP CLIENT mode by default. The default parameters related to the network are as follows:（1）Device IP: 192.168.1.200（2）Subnet mask: 255.255.255.0（3）Default gateway: 192.168.1.1（4）Module port: 2000（5）Destination IP: 192.168.1.100（6）Destination port: 1000（7）Number of reconnection: unlimitedUART related default parameters are:（1）Baud rate: 9600（2）Timeout: 0（3）Data bit: 8.

The detailed circuit reference file: CH9121PCB (please download in our official website).U1 is the main control chip CH9121. TXD1 and RXD1 are compatible with 3.3V and 5V level, and the RS485 control pin DIR can be suspended if not used.P1 is RJ45 port, with built-in network transformer, used to connect network equipments such as switches and router. It contains two pairs of Ethernet differential signals.When actually making a PCB, R5-R8, C6, and C7 should be as close as possible to the 5th pin of P1. The 0.1 uF decoupling capacitors for 3.3V and 1.8V pins are omitted in the figure. TXOP (RXIP) and TXON. (RXIN) are differential signals. When wiring, they should be wired close to parallel, and try to provide ground wire or copper coating on both sides to reduce external interference. The length of relevant signals of crystals XI and XO should be shortened as much as possible. In order to reduce the interference of high-frequency clock for the outside, the baselines should be surrounded or copper should be clad around relevant components.。
