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.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 V = 15V. The advanced input filter of HIN provides protection against short-pulsed input signals caused by noise.The UVLO circuits prevent malfunction when V are lower than the specified threshold voltage. The high-current and low-output voltage-drop feature makes this device suitable for the PDP sustain pulse driver, motor driver, switching mode power supply, and high-power DC-DC converter applications.
