Introduction

NCD57001F is a variant of NCD57001 with reduced Soft−Turn−Off time suited to drive large IGBTs or power modules. NCD57001F is a high−current single channel IGBT driver with internal galvanic isolation, designed for high system efficiency and reliability in high power applications. Its features include complementary inputs, open drain FAULT and Ready outputs, active Miller clamp, accurate UVLOs, DESAT protection, and soft turn−off at DESAT. NCD57001F accommodates both 5 V and 3.3 V signals on the input side and wide bias voltage range on the driver side including negative voltage capability. NCD57001F provides >5 kVrms (UL1577 rating) galvanic isolation and >1200 V_{iorm} (working voltage) capabilities. NCD57001F is available in the wide−body SOIC−16 package with guaranteed 8 mm creepage distance between input and output to fulfill reinforced safety insulation requirements.
