BQ25898: STAT=Low condition

Toshiro Imi

Part Number: BQ25898

Hello,

Our customer asked about STAT=Low condition in detail. As datasheet "9.2.9.2 Charging Status" mentioned STAT=Low state during Charging in progress. Does "Charging in progress" mean BATFET drive a current to battery. in other word, "Charging in progress" condition is defined by BATFET current ICHG flows from SYS to BAT direction.

Imi,

Charging in progress means the device is trying to regulate VBAT to charging voltage (VREG). If a battery is connected to the VBAT pin, there should be charge current flowing into the battery.

Thanks,

Ning.

Thank you for your help.

I understand that "Charging in progress" is the condition a charging current flows to a battery via BATFET.

This resolved customer question.
