Dear user,
The bq51020 has a pin (/AD_EN) that gets pulled down whenever it detects a voltage (Adapter/USB voltage) in the AD pin. This allows bq51020 to turn on an external PMOS FET that would connect adapter or VBUS power to the OUT pin (system side) bypassing wireless power. However the device has no way to do OTG or detect an OTG supply on the OUT pin and connect to the AD (VBUS) supply, so OTG is not supported.
