This application discussion expands the bq51003 in a Qi-compliant system from the previous solution and adds a secondary DC input. The bq51003 reacts to the added power and disables wireless power transfer then passes the DC voltage. When the DC voltage is removed, the bq51003 reinitiates wireless power transfer then enables its OUT pin.
