FAN7171MX-F085

The FAN7171_F085 is a monolithic high-side gate drive IC, which 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. 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 sustaine switch driver and energy recovery switch driver in the Plasma Display Panel application, motor drive inverter, switching power supply, and high-power DC-DC converter applications.
