Description

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 highside driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to V inputs are compatible with standard CMOS or LSTTL output, down to 3.3V logic. The UVLO circuit prevents malfunction when V fied 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.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating cond itions may affect device reliability. The absolute maximum ratings are stress ratings only. TA=25°C unless otherwise specified.
