What is Gate driver?
A circuit that receives control signals and drives a power device's gate with the right voltage and enough current. Many include isolation or level shifting to drive high-side switches.
Field: Power semiconductors
Gate driver in the explanations
A gate driver takes a few-mA signal from a microcontroller and delivers this drive at the proper gate voltages (e.g., +15–18 V and a negative off-bias for SiC).
What is the main role of a gate driver for power semiconduc…Turning the MOSFET off negatively biases the HEMT gate, switching it off automatically, so the pair behaves as a normally-off device driven by a standard silicon MOSFET gate driver.
