bq2410X automatic battery cut off circuit

Knighty Nimp

can anyone tell me if bq2410X family can detect low battery voltage. I found application note SLUA376 (page 10, fig 10) mention about power path selector between adaptor and battery and it would be grate if it can automatic disconnect battery from system load when detect battery low voltage .

Thanks

No, your battery pack should be able to detect low battery voltage.

Thanks.

I've got a few different battery packs to test this, and all allowed their voltage to get quite low, too low for me to want to continue testing. In any case the safety cuttoff voltage of the battery pack is likely to be lower than you want it to get for battery health. So in my mind there is the safety low battery voltage integrated into the battery. But also it would be nice if there was a battery health or device low battery low detection.
