Hello,
The BQ25882 is a battery charge controller with power path. In the case we connect a proper power supply on VBUS pin (eg 5VDC) & there is no battery connected on BAT. Does the internal boost converter works? What is the voltage on the SYS pin? Is the IC is able to power supply the system with just DC source connected on VBUS?
I have a 2nd question when BQ25882 is in stand alone mode without any connection to an host. When a battery is connected to the device and /CE pin is low and valid power supply is applied on VBUS, does the battery charge starts automatically without any commands transmitted via I²C.
Kind Regards
