Description

The FAN7384 is a monolithic half-bridge gate-drive IC

designed for high voltage, high speed driving MOSFETs

and IGBTs operating up to +600V.

Fairchild’s high-voltage process and common-mode

noise canceling technique provide stable operation of

high-side drivers under high-dv/dt noise circumstances.

An advanced level-shift circuit allows high-side gate

driver operation up to VS = -9.8V (typical) for VBS =15V.

The UVLO circuits prevent malfunction when VDD and

VBS are lower than the specified threshold voltage.

Output drivers typically source/sink 250mA/500mA,

respectively, which is suitable for half-bridge and full-

bridge applications in motor drive systems.
