Abstract: A power circuit having a reverse voltage recovery boost circuit that speeds up a recovery time of the power circuit after a reverse voltage condition has cleared is provided. The power circuit includes a reverse voltage detector that detects the reverse voltage condition. After the reverse voltage condition clears, the reverse voltage recovery boost circuit transfers a portion of power to one transistor that is stored in another transistor thereby transitioning the one transistor from a non-conductive state to a conductive state, which allows a transfer of power from the input voltage to the output voltage.

Abstract: A power supply system for USB Power Delivery includes a current source drive circuit to control a power FET to regulate the supply of power along a power path. The current source drive circuit includes a cascode current source and a cascode protection circuit formed by a source follower and a feedback voltage divider. The source follower can be a transistor with its gate connected to a cascode node between upper- and lower-stage transistors of the cascode current source. The divider node of the voltage divider is connected to the gate of the lower-stage transistor. The current source drive circuit can operate within the gate-source voltage specifications of 30-volt DEPMOS devices, and can provide high output impedance to the gate of power FET and a current limit circuit during current limiting operation, without requiring an extra high-voltage mask during fabrication.

Abstract: A switch includes a power transistor configured to switch an input voltage to a load. The switch further includes a charge pump and a duty cycle controller. The charge pump is coupled to the power transistor and includes an enable input to cause the charge pump to be turned on and off. The duty cycle controller is coupled to the charge pump and is configured to duty cycle the charge pump based on a comparison of a signal of a gate of the power transistor to a reference signal.
