The bq24350/2 is a highly integrated circuit designed to provide protection to Li-ion batteries from failures of the charging circuit. The IC continuously monitors the input voltage and the battery voltage. In case of an input over-voltage condition, the IC will turn off the internal power FET after a blanking time. If the battery voltage rises to unsafe levels during charging process, power is removed from the system. If the input current exceeds the over current threshold for a limited time, the IC will turn off the output power. The integrated charging FET can regulate the charge voltage and current according to the control from the host. The device can also provide a voltage source with over voltage and over current protection for host controller.

参考设计

TIDA-00033 — 具有 FET 的过压和过流充电器前端保护 IC 参考设计

该参考设计是一款高度集成的电路解决方案，旨在保护锂离子电池免受充电电路故障的影响。该 IC 设计可持续监控输入电压和电池电压。如果发生输入过压的情况，则该 IC 将在消隐时间后关闭内部电源 FET。如果在充电过程中电池电压增加到不安全水平，则将移除系统电源。如果输入电流在有限时间内超出过流阈值，则该 IC 设计将关闭输出电源。集成式充电 FET 可根据主机的控制来调节充电电压和电流。该设计还可提供为主机控制器提供带过压和过流保护功能的电压源。
