Abstract: Exemplary embodiments are related to detecting a reverse-boosting operation of a battery charger. A device may include a plurality of switches for receiving an input voltage at an input port and conveying an output voltage. The device may also include a first sensing device coupled to the input port configured to detect if an input current is less than a threshold current. Further, the device may include a second sensing device selectively coupled to the input port to detect if the input voltage is less than a threshold voltage.
