Description
The FAN7391 is a monolithic high- and low-side gatedrive 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.
Fairchild’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...
