Overview
The NCV57001FDWR2G is a high-current, single-channel IGBT gate driver from onsemi, designed for high system efficiency and reliability in high-power applications. This component is a variant of the NCV57001 with reduced Soft-Turn-Off time, making it suitable for driving large IGBTs or power modules. It features internal galvanic isolation, complementary inputs, open-drain FAULT and Ready outputs, active Miller clamp, accurate Under-Voltage Lockout (UVLO), DESAT protection, and soft turn-off at DESAT. The driver accommodates both 5 V and 3.3 V signals on the input side and a wide bias voltage range on the driver side, including negative voltage capability.
