ONSEMI FAN7392 High-Current, High- & Low-Side, Gate-Drive IC

The FAN7392 is a monolithic high− and low−side gate drive IC, that 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. ON Semiconductor’s 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. Logic inputs are compatible with standard CMOS or LSTTL output, down to 3.3 V logic. The UVLO circuit prevents malfunction when VCC and VBS are lower than the specified threshold voltage. The high−current and low−output voltage drop feature makes this device suitable for half− and full−bridge inverters, like switching−mode power supply and high−power DC−DC converter applications.
