产品简介

CXPR7134A是一种保护IC,它包括高精度电压检测器和电流检测器,为电动工具、笔记本电脑等应用中使用的5系列锂离子/聚合物电池组提供过电压(OV)、欠电压(UV)、过电流(OC)、短路(SC)、超温(OT)、低温(UT)保护提供一个特定的控制引脚来控制充电和放电场效应管。当CTRL浮动时,CXPR7134A将进入待机状态以节省功耗。在待机状态下,放电场效应管关闭,而电荷场效应管打开。当CTRL连接到VCC管脚时,CXPR7134A工作在正常状态,但是充放电FET都关闭。当CTRL与VSS引脚连接时,cxpr7134a工作在正常状态,充放电场效应管的状态根据安全事件来决定。CXPR7134集成了FET驱动器。CXPR7134Acan直接驱动组件侧的N型电荷场效应管和N型放电场效应管。CXPR7134A在正常状态下从VCC消耗小于30uA,在待机状态下减少到小于3uA,在断电状态下减少到小于1uA。此外,CXPR7134A可以由开关电源供电,提供了一种将电池组电流消耗降低到零的技术

The CXPR7134A is a protection IC which includes highaccuracy voltage detector and current detector to provide Over-Voltage (OV), Under-Voltage (UV), Over-Current (OC), Short-Circuit (SC), OverTemperature (OT), Under-Temperature (UT) protection for 5-series Li-ion/polymer battery pack used in power-tools, notebook PC applications etc. The CXPR7134A provides a specific CTRL pin to control both charge and discharge FET. When CTRL is floating, the CXPR7134A will enter standby state to save power consumption. Under standby state, discharge FET is turned off while charge FET is turned on. When CTRL is tied to VCC pin, the CXPR7134A works in normal state, however, both charge and discharge FET are turned off. When CTRL is tied to VSS pin, the CXPR7134Aworks in normal state, the state of charge and discharge FET are decided according to safety events. The CXPR7134Aintegrates FET driver. The CXPR7134Acan drive the N-type charge FET and N-type discharge FET at the PACK- side directly. The CXPR7134Aconsumes less than 30uA in normal state from VCC, and it reduces to less than 3uA in standby state and less than 1uA in power-down state. Furthermore, the CXPR7134Acan be powered from a switched supply, providing a technique to reduce battery stack current draw to zero. This device is packaged in a 16-pin TSSOP package.
