FAN7384

Half Bridge Gate Driver

General DescriptionGeneral 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 fullbridge applications in motor drive systems.
