Tool/software:
Hello,
We are using the BQ25792 with a TPS25750D and a 4S LI ION battery for a USB-C PD 20V 3A application.
1) The charger is perfect until we tried the SFET function.
QON is low under 400mV but every 10 or 20s (depending if you add the 10s delay), the BQ reset the card and SDRV is tied to ground.
The mos is ok too and his gate is directly tied to SDRV.
We try with different boards and this issue is recurrent.
Have you some ideas to correct that ?
2) Can you confirm me the recommanded current max for sys pin please ?
Best regards
