Hi TI team,

I checked the E2E forum below.

I want to set the adapter output to 9V. but the adapter voltage is being output at 12V.

Can't BQ25895 set the adapter output to 9V?

Please check.

Thanks

Downey Kim.

Downey,

Please use pin-compatible BQ25890H instead.

Thanks,

Ning.

Hi Ning,

I couldn't find the 9V setting in the BQ25980H's Datasheet.

Does your answer mean if I use the BQ25890H instead of the BQ25895 i get 9V output?

Thanks,

Downey.

Downey,

BQ25890H has added EN_12V (REG01[1]), so that it may goes to 9V instead of 12V. By default 12V protocol is disabled, handshaking supports 5V/9V only.

REG01

Thanks,

Ning.
