Original FAN7391MX Marking FAN7391 Half-Bridge Gate Driver IC Non-Inverting 14-SOIC for PSU WhatsPower PSU3300-01 PLUS1

Description

The FAN7391 is a monolithic high− and low−side gate−drive IC, which can drive high−speed MOSFETs and IGBTs that operate up to +600 V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. High−voltage process and common−mode noise−canceling techniques provide stable operation of the high−side driver under high−dv/dt noise circumstances. An advanced level−shift circuit offers high−side gate driver operation up to VS = −9.8 V (typical) for VBS = 15 V. The advanced input filter of HIN provides protection against short−pulsed input signals caused by noise. The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. The high−current and low−output voltage−drop feature makes this device suitable for the PDP sustainable pulse driver, motor driver, switching mode power supply, and high−power DC−DC converter applications.
