Other Parts Discussed in Thread: BQ25890
Hello Sir:
We are using BQ25892 and have one question.
If pin 24 connected to VBUS, will there be any side effects?
Please let us know your recommendations.
Thanks a lot.

Hi Statham,
DSEL is a open drain device. Without a pull up resistor, its pull down transistor could pull too much current and become damaged. Shortly VBUS to DSEL is not recommended.

HI Statham,
My apologies. I was referring to BQ25890. I will need to confirm with the team whether the 892 NC is truly not connected or is simply the DSEL pin. Unfortunately, all of the team is on holiday until next week.

Hi Statham,
It should be low risk to connect the pin 24 to VBUS.
Thanks,
Ning.
