A gate driver circuit amplifies low-power control signals from a microcontroller or PWM controller to the voltage and current levels needed to drive the gate of a power semiconductor device, ensuring efficient and reliable switching.
Key parameters include peak output current, output voltage swing, switching frequency, propagation delay, rise/fall time, supply voltage, operating temperature, isolation voltage, CMTI, input logic level, package type, and power dissipation. These must match the requirements of the power device and application.
Isolation protects low-voltage control circuitry from high-voltage transients in the power stage. It is achieved using optocouplers or transformers and is specified by isolation voltage ratings such as 2.5–5 kVrms.
Common protection features include under-voltage lockout (UVLO), desaturation detection, and short-circuit protection, which help prevent damage to the power device and the driver itself.
