BQ25713: operational mode

Part Number: BQ25713

Does the device have a register which can be read and shows the operational mode of the buck / boost?  (ie...Buck/Boost, OTG Buck.OTG Boost)

    Hi David,

    Unfortunately no not really. However, you can always do an ADC of VBUS and VBAT/VSYS to see what is going on. If VBUS > VBAT/VSYS, it is in buck mode. If VBUS < VBAT/VSYS, then it is in boost mode.

    "IN_OTG" bit of ChargerStatus Register can be used to identify whether the device is in OTG.

    Thanks and I hope this helps,

    Peng
