Abstract
Exemplary embodiments are directed to power path switching between multiple charging ports of an electronic device. A device may include a charging port of a plurality of charging ports for coupling to a power supply via an over-voltage protection circuit. The device may further including a comparison unit configured to couple the charging port to the power supply based at least partially on a comparison between a voltage at an input of the over-voltage protection circuit coupled to the charging port with a voltage at the output of the over-voltage protection circuit coupled to the power supply.
