您好，我使用BQ21040这颗芯片作为充电芯片，假设产品内置的锂电池损坏，电池电压低于1V（且充电电池电压不会回升至2.5V以上），输入端5V进入后，充电芯片是否会进行30min的预充电，30min结束后电压仍低于2.5V会停止充电。另外是否每次5V接入后，都会进行一轮上述流程。
您好，数据手册介绍会截止充电。
If either the 30 minute or ten hour timer times out, the charging is terminated and the CHG terminal goes high impedance if not already in that state.
