Gate Drivers

Gate Driver ICs are high-current buffer amplifiers designed to bridge low-power control signals from microcontrollers or PWM controllers with the gates of high-power switching devices, such as power MOSFETs, IGBTs, Silicon Carbide (SiC) MOSFETs, and Gallium Nitride (GaN) FETs. Because power switches present large capacitive loads at their gates, gate drivers must deliver amperes of peak current within nanoseconds to ensure fast turn-on and turn-off times, minimizing switching power losses and thermal buildup.

Gate drivers are available in low-side, high-side, half-bridge, and optically or magnetically isolated configurations (isolated gate drivers). Selection parameters include peak output drive current (sink/source, typically 1A to 10A), propagation delay, slew rate control, common-mode transient immunity (CMTI) for SiC/GaN, and integrated safety protection features such as Under-Voltage Lockout (UVLO) and desaturation (DESAT) short-circuit detection.
