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.

Abstract: Exemplary embodiments are directed to systems, devices, methods, and computer-readable media for calibrating a charging current. A device may include a charger for conveying an output voltage to a chargeable device. The device may also include a monitoring system including an analog-to-digital converter for measuring a current received by the chargeable device. Further, the device may include a control device configured to receive a charging current value from the monitoring system and convey a signal to the charger in response to a comparison of the charging current value to a target current value.
