BQ25720: COMPIN trigger PROCHOT

Part Number: BQ25720

Hi team,

customer report COMPOUT and PROCHOT are low,

I know because COMPIN is 3.3V>1.2V threshold,

so i try to short it as 0V.

but when I short the PR4437 during the middle of operation,

the prochot wasn't  back to high, instead it's still low.

what should I do? should I reboot again?
