NCD57000 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, soft turn−off at

DESAT, and separate high and low (OUTH and OUTL) driver outputs

for system design convenience. NCD57000 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. NCD57000 provides

> 5 kVrms (UL1577 rating) galvanic isolation and > 1200 VIORM

(working voltage) capabilities. NCD57000 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.
