Abstract: A power management system that can include an application processor and a power management unit (PMU). The PMU can generate a regulated output voltage based on control signals generated by a switch control module of the application processor. The control signals can be determined based on a comparison of monitored voltages within the application processor and a generated reference voltage. The reference voltage can be generated based on fed back signals corresponding to the control signals. The application processor and the PMU can be formed utilizing different size manufacturing process technologies. For example, the PMU can be formed utilizing a larger size manufacturing process technology than the application processor.

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.

Abstract: A wireless power transfer (WPT) receiver circuit includes a receive coil to couple to a transmit coil of a WPT transmitter circuit. A rectifier is coupled to the receive coil to generate a rectified voltage. The rectifier comprises a bridge rectifier circuit including a first set of switching elements. A load modulation circuit facilitates communication between the WPT receiver circuit and the WPT transmitter circuit. The load modulation circuit includes a single modulation capacitor and one or more modulation switching elements. At least one node of one of the modulation switching elements is connected to an input node of the rectifier.
