onsemi NCV57000 Isolated High Current IGBT Gate Driver

onsemi NCV57000 Isolated High Current IGBT Gate Driver with internal galvanic isolation is designed for high system efficiency and reliability in high-power applications. The NCV57000 has robust features, including complementary inputs, open drain FAULT and Ready outputs, an active Miller clamp, accurate UVLOs, DESAT protection, soft turn-off at DESAT, and separate high and low (OUTH and OUTL) driver outputs for system design convenience. It accommodates both 5V and 3.3V signals on the input side and a wide bias voltage range on the driver side, including negative voltage capability. The IGBT provides >5kVrms (UL1577 rating) galvanic isolation and >1200Viorm (working voltage) capabilities. The NCV57000 Isolated High Current IGBT Gate Driver is packaged to fulfill reinforced safety insulation requirements. It is offered in the wide-body SOIC-16 package with a guaranteed 8mm creepage distance between input and output.
