3/4/5节Li离子/Li聚合物电池用保护IC
R5432VxxxXX 系列
■概要
IC功能和架构： R5432VxxxXX系列是基于高耐压CMOS工艺的、用于Li离子/Li聚合物可充电电池的电池保护IC，可实现对3、 4、5节电池的过充电、过放电、放电过电流、短路过电流以及充电过电流状态的检测和保护。内置电压检测器、短路检测器、基准电压源、振荡器、计数器、延时电路、逻辑电路等。信号输出端形态：COUT引脚是P 沟道漏极开路输出，驱动N管；DOUT引脚是CMOS输出。保护功能：过充电及充电过电流保护过程：IC一旦检测出过充电或充电过电流，在IC内置延时过后, COUT输出“HiZ” 态。过放电及放电过电流保护过程：IC一旦检测出过放电或放电过电流，在电容设定的外置延时过后，DOUT 输出“L”电平。保护解除功能：过充电保护解除：当电池电压下降到比过充电解除电压阈值低时，过充电保护被解除，COUT输出变回“H” 电平。充电过电流保护解除：移除充电器并接上负载，充电过电流保护被解除，COUT输出变回“H”电平。过放电保护解除：当电池电压上升到比过放电解除电压阈值高时，过放电保护被解除，DOUT输出变回“H” 电平。放电过电流及短路保护解除：过流保护锁定时，外置的过流锁定/解除回路是导通的；移除负载后，该回路上的电阻会将IC的VMP引脚电压拉低，从而解除过流及短路保护状态，DOUT输出变回“H”电平。测试时间短缩功能：通过设置SEL1,SEL2引脚的电压，可使保护电路板进入测试时间短缩模式。该模式中，过充电、过放电、过电流的各种检测延时可以缩短为设定值的约1/80。级联功能：通过级联两片R5432V系列IC，可构成多节电池组保护电路，用于保护6节以上可充电电池串联形成的电池组。级联连接方式：方案图中高端的IC的COUT和DOUT分别连接低端的IC的CTLC和CTLD。通过这种方式，高端的IC的COUT和DOUT翻转信号可以传送到低端的IC，使低端的IC动作，从而实现对充放电MOSFET的间接控制。电池均衡功能： R5432V系列IC有电池均衡功能，用于均衡多节电池的电压不平衡。充电时，当电池电压超过均衡检测电压阈值时，电池均衡控制引脚(CBx端)的信号翻转，打开外部均衡支路的NMOSFET开关管，均衡功能启动：充电电流被分流。注意：即使充电结束，均衡支路仍然会导通一段时间，电池通过该支路放电，直到电池电压低于均衡释放电压时，均衡支路才关闭。断线检测功能：当电池和保护板之间的连接线断开时，R5432V可以检测出这种断线状态，并使COUT输出“HiZ”，从而实施断线保护。断线保护后，通过将电池和保护板之间的断线重新连接，COUT输出变回“H”电平，从而解除断线保护。

The CS42324 performs stereo analog-to-digital (A/D) and up to four channels of digital-to-analog (D/A) conversion of up to 24-bit serial values at sample rates up to 96kHz.A 5:1 stereo input multiplexer is included for selecting between line-level inputs. The output of the input multi-plexer is followed by an advanced 3rd-order, multi-bit delta-sigma modulator and digital filtering/decimation. Sampled data is transmitted by the serial audio inter-face at rates from 4kHz to 96kHz, in either Slave or Master Mode.The D/A converter is based on a 5th-order multi-bit del-ta-sigma modulator with an ultra-linear low-pass filter and offers a volume control that operates with a 0.5dB step size. It incorporates selectable soft ramp and zero crossing transition functions to eliminate clicks and pops.An integrated 7:1 stereo output multiplexer on each of the three stereo 2 Vrms line-level outputs is used to se-lect any of the 5 stereo analog inputs, for analog bypass support, or the outputs of the 2 internal DACs. Each 2Vrms output can be muted with the selectable analog mute function.Standard 50/15μs de-emphasis is available for a 44.1kHz sample rate for compatibility with digital audio programs mastered using the 50/15μs pre-emphasis technique.Integrated digital level translators allow easy interfacing between the CS42324 and other devices operating over a wide range of logic levels.The CS42324 is available in a 48-pin LQFP package in Commercial (-40°C to +85°C) and Automotive (-40°C to +105°C) grades. The CDB42324 Customer Demonstra-tion board is also available for device evaluation and implementation suggestions.

MILITARY AND COMMERCIAL TEMPERATURE RANGESJANUARY 1995©1995 Integrated Device Technology, Inc.6.17DSC-4203/5The FCT543T/FCT2543T is a non-inverting octal trans-ceiver built using an advanced dual metal CMOS technology.This device contains two sets of eight D-type latches with separate input and output controls for each set. For data flow from A to B, for example, the A-to-B Enable (CEAB ) input must be LOW in order to enter data from A 0–A 7 or to take data from B 0–B 7, as indicated in the Function Table. With CEAB LOW,a LOW signal on the A-to-B Latch Enable (LEAB ) input makes the A-to-B latches transparent; a subsequent LOW-to-HIGH transition of the LEAB signal puts the A latches in the storage mode and their outputs no longer change with the A inputs.With CEAB and OEAB both LOW, the 3-state B output buffers are active and reflect the data present at the output of the A latches. Control of data from B to A is similar, but uses the CEBA , LEBA and OEBA inputs.The FCT2543T has balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot and controlled output fall times-reducing the need for external series terminating resistors. FCT2xxxT parts are plug-in replacements for FCTxxxT parts.1•Common features:–Low input and output leakage ≤1µA (max.)–CMOS power levels–True TTL input and output compatibility – V OH = 3.3V (typ.)– V OL = 0.3V (typ.)–Meets or exceeds JEDEC standard 18 specifications –Product available in Radiation Tolerant and Radiation Enhanced versions–Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked)–Available in DIP, SOIC, SSOP, QSOP, CERPACK and LCC packages •Features for FCT543T:–Std., A, C and D speed grades–High drive outputs (-15mA I OH , 64mA I OL )–Power off disable outputs permit “live insertion”•Features for FCT2543T:–Std., A, and C speed grades–Resistor outputs (-15mA I OH , 12mA I OL Com.)(-12mA I OH , 12mA I OL Mil.)–Reduced system switching noiseFAST CMOS OCTAL LATCHED TRANSCEIVERMILITARY AND COMMERCIAL TEMPERATURE RANGES6.172PIN CONFIGURATIONSDIP/SOIC/SSOP/QSOP/CERPACKTOP VIEWGNDA 0A 1A 2VccB 0A 3A 4A 5A 6A 7B 1B 2B 3B 4B 5B 6B 7OEABCEBA LCC TOP VIEWG N N CNC B 1B 2B 3B 4B 5B 6A C E AB B L E A B O E A B 2613 drw 022613 drw 03FUNCTION TABLE (1, 2)For A-to-B (Symmetric with B-to-A)2613 tbl 021.* Before LEAB LOW-to-HIGH TransitionH = HIGH Voltage Level L = LOW Voltage Level— = Don’t Care or Irrelevant2.A-to-B data flow shown; B-to-A flow control is the same, except usingCEBA , LEBA and OEBA .(1)NOTES:1.Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-INGS may cause permanent damage to the device.

Installation Instructions for the DS7432 Eight Input Remote Module
1.0 Description
The DS7432 is an Eight Input Remote Module that provides a means of addressing up to eight input loops of conventional contacts to the multiplex bus of the control. If using separate powered detectors (other than smoke detectors) with a DS7400 Series Control/ Communicator, the DS7432 can be powered from the control panel auxiliary power (terminals 7 and 8). The detector can be connected to the DS7432 (see Figure 4). This eliminates the need for home-run power wiring from each detector to the control when the DS7432 is mounted outside of the enclosure. Be sure all wiring is unpowered before routing.

Its function is similar to the 74F299 with the exception of Synchronous Reset. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count.Separate serial inputs and outputs are provided for Q 0 and Q 7 to allow easy cascading. Four operation modes are possible: hold (store), shift left, shift right and parallel load.Featuress Common parallel I/O for reduced pin count s Additional serial inputs and outputs for expansion s Four operating modes: shift left, shift right, load and store s 3-STATE outputs for bus-oriented applicationsOrdering Code:Devices also available in T ape and Reel.

All flip-flop outputs are brought out through 3-STATE buffers to separate I/O pins that also serve as data inputs in the parallel load mode. Q 0 and Q 7are also brought out on other pins for expansion in serial shifting of longer words.A LOW signal on SR overrides the Select inputs and allows the flip-flops to be reset by the next rising edge of CP . All other state changes are also initiated by the LOW-to-HIGH CP transition. Inputs can change when the clock is in either state provided only that the recommended setup and hold times, relative to the rising edge of CP , are observed.A HIGH signal on either OE 1 or OE 2 disables the 3-STATE buffers and puts the I/O pins in the high impedance state.In this condition the shift, load, hold and reset operations can still occur. The 3-STATE buffers are also disabled by HIGH signals on both S 0 and S 1 in preparation for a paral-lel load operation.Mode Select TableH = HIGH Voltage Level L = LOW Voltage Level X = Immaterial= LOW-to-HIGH transitionLogic DiagramPlease note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.Pin Names DescriptionU.L.Input I IH /I IL HIGH/LOW Output I OH /I OL CP Clock Pulse Input (Active Rising Edge) 1.0/1.020 µA/−0.6 mA DS 0Serial Data Input for Right Shift 1.0/1.020 µA/−0.6 mA DS 7Serial Data Input for Left Shift 1.0/1.020 µA/−0.6 mA S 0, S 1Mode Select Inputs1.0/2.020 µA/−1.2 mA SR Synchronous Reset Input (Active LOW) 1.0/1.020 µA/−0.6 mA OE 1, OE 23-STATE Output Enable Inputs (Active LOW) 1.0/1.020 µA/−0.6 mA I/O 0–I/O 7Multiplexed Parallel Data Inputs3.5/1.08370 µA/−0.65 mA 3-STATE Parallel Data Outputs 150/40 (33.3)−3 mA/24 mA (20 mA)Q 0, Q 7Serial Outputs50/33.3−1 mA/20 mAInputs ResponseSR S 1S 0CP L X X Synchronous Reset; Q 0–Q 7 = LOW H H H Parallel Load; I/O n → Q nH L H Shift Right; DS 0 → Q 0, Q 0 → Q 1, etc.H H L Shift Left; DS 7 → Q 7, Q 7 → Q 6, etc.HLLXHold74F323Absolute Maximum Ratings (Note 1)Recommended Operating ConditionsNote 1: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired.

数字电位器max5402中文资料

Max5402的H脚与L脚之间包含255个串联的固定电阻。

可调端（W引脚)可以通过编程连到任意一个抽头上。

Max5402具有SPI兼容的三线串行数据接口，这个只写（write-only)的接口包含三个输入：片选（CS非），数据in（DIN），和数据时钟（SCLK）。

当CS非是低时，在每一个SCLK脉冲的上升沿（图1），Din脚出来的数据同步的装载到8位串行移位寄存器。

MSB先移动，如图3所示。

注意，如果CS非在全部数据流期间没有一直保持低电平，数据将被破坏，需要重新下载。

当8位数据全部装载到移位寄存器后，一旦CS非为高电平，数据立即锁存到解码器。

解码器使电位器抽头移动到8bit输入数据对应的位置。

对于max5402，每一个电阻单元是10KΩ/256,即39..2Ω。

Max5402具有POR电路特性。

当上电时，通过将二进制数128移到锁存器，电位器抽头处于
中间位置。

将W连接到H或L，可以当作可变电阻。
