Part Number:BQ24715
HI Sir,
my customer used TI BQ24715 for 2s Battery charging, now the battery discharged to deeply discharged( the battery Discharge cut-off voltage is 6V set by the battery protection board ). as the battery has about 0.4mA Quiescent Current, so the 2s cell voltage will drop down from 6V to 2V. when the 2s cell voltage drop down below 3.6V, The bq24715 can't active the battery pack to charge.
but the DC power supply can active the batter pack to charge. so customer confused that why the DC power supply can active the 2V cell Battery ,but the BQ24715 can't. please give me some suggestion to debug,TKS.
