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.
