NCP51820 High-Performance 650 V Half-Bridge Gate Driver for GaN Power Switches

ON Semiconductor’s NCP51820 driver offers protection functions such as independent UVLO and IC thermal shutdown

Image of ON Semiconductor's NCP51820 High-Performance 650 V Half-Bridge Gate Driver for GaN Power SwitchesON Semiconductor’s 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 undervoltage lockout (UVLO) and IC thermal shutdown.
