onsemi isolated gate driver NCD57080

Isolated high current gate driver for high system efficiency

NCD57080A, NCD57080B and NCD57080C are high−current single channel IGBT gate drivers with 3.75 kVrms internal galvanic isolation, designed for high system efficiency and reliability in high power applications. The devices accept complementary inputs and depending on the pin configuration, offer options such as Active Miller Clamp (NCD57080A), negative power supply (NCD57080B) and separate high and low (OUTH and OUTL) driver outputs (NCD57080C) for system design convenience. NCD57080 (A/B/C) accommodate wide range of input bias voltage and signal levels from 3.3V to 20V. NCD57080 (A/B/C) are available in narrow-body SOIC-8 package.
