GATE DRIVER CIRCUIT FOR HIGH SIDE SWITCHES

摘要

A gate driver circuit for driving a high-side switch is disclosed. The gate driver circuit has a sample and a level shift circuit. The sample and level shift circuit is connected to the high side switch. The gate driver circuit also has a sampling capacitor. The sampling capacitor is configured to sample an output voltage of at least one amplifier. The gate driver circuit additionally contains at least one voltage supply. The at least one voltage supply is connected to the at least one amplifier. The sense capacitor is configured to charge a gate capacitance of the high-side switch and the at least one amplifier is configured to limit an output current of the high-side switch.
