Abstract
A voltage dedicated charger apparatus includes an AC-to-DC converter circuit, a pair of switches, and a controller block. The AC-to-DC converter circuit converts an AC input voltage to a DC output voltage. The pair of switches is operable to isolate a pair of data ports from the AC-to-DC converter circuit. The pair of data ports includes a DP port and a DN port. The controller block includes a monitor circuit, a transceiver, and a control circuit. The monitor circuit monitors the DP and DN ports of the apparatus. The transceiver receives one or more messages form a charge-receiving device and communicate data to the charge-receiving device. The control circuit controls operation of the pair of switches based on a signal from the monitor circuit.
