1200V High-Current, Half-Bridge, Gate-Driver IC (HVIC)

Favorite

Overview

The FAN73912 is a monolithic half bridge gate-drive IC designed for high-voltage and high-speed driving for MOSFETs and IGBTs that operate up to +1200V.
The advanced input filter of HIN provides protection against short-pulsed input signals caused by noise.
An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8 V (typical) for VBS=15 V. The UVLO circuit prevents malfunction when VCC and VBS are lower than the specified threshold voltage.
Output drivers typically source and sink 2 A and 3 A, respectively.
