Description

The FAN73711 is a monolithic high-side gate drive IC that can drive high-speed MOSFETs and IGBTs operating 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. The UVLO circuit prevents malfunction when VBS is lower than the specified threshold voltage.

The high-current and low-output voltage drop feature makes this device suitable for sustain and energy recovery circuit switches driver in the plasma display panel application, motor drive inverter, switching power supply, and high-power DC-DC converter applications.
