Part Number: BQ25703A

Hi Team,

Can BQ25703A be used on application scenarios below:
1. Charging: the type-C charger is 5V (the input voltage range is within 5-12V), and the battery is 8.4V in series, which needs boost and fast charging function.
2. When it is not charging, the TYPE-C interface is used as USB host, which power supply to the outside of 5V/1-2A.

Beat Regards,
Tom Liu

    Hi Liu Yang,

    BQ25703A can boost input voltage from 5V to 8.4V(or buck down from 12 to 8.4V). On the other hand, in OTG mode, it can supply power from battery to VBUS. Should this meet your application requirement? 

    Best Regards.
