US 12,676,601 B2 · Systems and methods for high-voltage power integrated circuits

Abstract

The present disclosure includes an integrated circuit having a housing, an optical port exposed on an exterior of the housing, and gate driver circuitry configured to generate a drive signal at an output of the integrated circuit to drive a gate terminal of a wide band gap (WBG) power device. The integrated circuit may include an optical receiver coupled to the optical port and having an electrical output coupled to an input of the gate driver circuitry, the optical receiver configured to receive an optical signal via the optical port and generate an electrical signal at the electrical output based on the optical signal. The integrated circuit may also include a power supply system configured to convert a first voltage to one or more power supply voltages powering the gate driver circuitry, the first voltage being a voltage at a terminal of the WBG power device.
