FAN7392: 625V, 3.3/5V input logic compatible, 3/3A sink/source current, High & Low side Gate-Drive with SD protection

The FAN7392 is a monolithic high- and low-side gate drive IC, that can drive high-speed MOSFETs and IGBTs that operate up to +600V. 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=-9.8V (typical) for VBS=15V. Logic inputs are compatible with standard CMOS or LSTTL output, down to 3.3V 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 halfand full-bridge inverters, like switching-mode power supply and high-power DC-DC converter applications.
