Part Number: BQ25302 Other Parts Discussed in Thread: BQ25306 Hi Expert,
This is Koki Tsushima.
My customer wants to use VSET less than 4.1V.
Is it possible?
I think this is impossible because Battery Regulation Voltage should be 4.1V/4.2V/4.35V/4.4V…

Part Number: BQ25302 Hi
If VBUS do not have power supply, does the discharge path correct? Battery --> buck inductor --> Q2 -->PMID ---> System
Does Q2 fully turn on or use the diode? If take this path, is there a current limit?
Thanks
