The NCP51820, a high-speed gate driver, is designed to meet the requirements of driving enhancement mode (e-mode) and gate injection transistor (GIT) GaN HEMT power switches in offline, half-bridge power topologies.

Both drive stages employ a voltage regulator to maintain the gate-source drive signal and to fully protect the gate of the GaN power transistor. The gate driver offers short and matched propagation delays as well as -3.5 V to +650 V (typical) common-mode voltage range for the high-side drive. It offers protection functions based on voltage monitoring and thermal shutdown.
