Other Parts Discussed in Thread: BQ25883, BQ25882
the BQ25886 has a pin called "VSET" to set battery charge voltage. Is it possible to replace the recommended programming resistor with a digital potentiometer (that is powered from VBUS). The idea of this setup is to have a possibility to program the battery charge voltage from a microprocessor and then store this setup in a NV memory.
My concern is that the BQ25886 could probe the programming resistor only during power up (when the battery is inserted). At that time Vbus is not present and as a result of this the programming resitor is invalid.
(Using the BQ25883 is no option for our application because we need the OTG pin)
Thank you for your help!
