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.
