Hi Yishan,
Most of the faults (e.g. TS fault) have a ~30ms deglitch before charge restarts after fault removal. Auto recharge following termination has adjustable deglitch from 64ms to 2s.

Jeff

Dear team,
Customer want to know if they can enable ship mode with adapter present? I checked the D/S seems ship mode only active with battery only. Is there a way to turn off ship FET with adapter?
If yes, please…
