CXPR7900

CXPR7900是一款充电器前端集成电路,旨在保护锂离子电池免受充电电路故障的影响。集成电路连续监测输入电压和蓄电池电压。该装置像线性调节器一样工作,在输入电压达到输入过电压阈值(VOVP=7.1V)的情况下保持5.1V的输出。在输入过电压条件下,集成电路立即关闭内部通场效应管,将充电电路与损坏的输入源断开。此外,如果充电时电池电压上升到不安全的水平,系统将断电。该集成电路还监测其模具温度,并在温度超过145℃时关闭。当IC由处理器控制时,IC向主机提供有关故障状况的状态信息

The CXPR7900 is a charger front-end integrated circuit designed to provide protection to Li-ion batteries from failures of the charging circuitry. The IC continuously monitors the input voltage and the battery voltage. The device operates like a linear regulator, maintaining a 5.1V output with input voltages up to the input over-voltage threshold (VOVP = 7.1V). During input over-voltage conditions, the IC immediately turns off the internal pass FET disconnecting the charging circuitry from the damaging input source. Additionally, if the battery voltage rises to unsafe levels while charging, power is removed from the system. The IC also monitors its die temperature and switches off if it exceeds 145℃. When the IC is controlled by a processor, the IC provides status information about fault conditions to the host.

The CXPR7900 is available in Green TDFN-2×2-8L package and is rated over the -40℃ to +85℃ temperature range.x3H嘉泰姆
