BQ25302: Recommended values for VBUS diode and PFET

Alfred von Loebbecke

Part Number: BQ25302

Hello,

What values are recommended for the VBUS diode and the PFET when using the BQ25302 in an application with an external power path (2A maximum)?

Thank you and regards,

Alfred

Hi Alfred,

It is up to the designer as this is a reference circuit. Keep in mind values of Qg, RDSon, drain current rating for the PFET. Rate diode for forward current > gate drive current required to charge the the Ciss of the PFET.
