Abstract: Apparatuses and methods to distinguish proprietary, non-floating and floating chargers for regulating charging current are disclosed. In one aspect, a charger detection circuit is provided in a portable electronic device. The charger detection circuit is configured to detect whether a connected Universal Serial Bus (USB) charger is compliant with a USB battery charging specification. If the connected USB charger is non-compliant with the USB battery charging specification, the charger detection circuit is configured to further detect if the non-complaint USB charger is a non-compliant floating USB charger or a non-compliant proprietary USB charger. If the connected USB charger is determined to be a non-compliant proprietary USB charger, the portable electronic device can be configured to draw up to a maximum charging current according to the USB battery charging specification.
