The NCP51820 high-speed gate driver is designed to meet the stringent requirements of driving enhancement mode (e?mode) and gate injection transistor (GIT) GaN HEMT power switches in offline, half-bridge power topologies. The NCP51820 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. To fully protect the gate of the GaN power transistor against excessive voltage stress, both drive stages employ a dedicated voltage regulator to accurately maintain the gate-source drive signal amplitude. The NCP51820 offers important protection functions such as independent under?voltage lockout (UVLO) and IC thermal shutdown.
