TPS2115A: use of external pullup on D1 input

Sal LaRussa

Part Number: TPS2115A

Hi,

are there any issues using an external 10K pullup (to a LiIon battery) on the D1 logic input of the TPS2115A? the LiIon battery will be one of the two power switch inputs (IN1) to this mux.

Thanks,

Sal

Hello Sal,

The D1 pin already has an internal pull-up; however, using a 10kΩ external pull-up to your LiIon battery is fine too.
