FAN7888 − 3 Half-Bridge Gate Drive IC

The FAN7888 is a monolithic three half-bridge gate-drive IC designed for high-voltage, high-speed driving MOSFETs and IGBTs operating up to +200 V.

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 V_S = -9.8 V (typical) for V_BS =15 V.

The UVLO circuits prevent malfunction when V_DD and V_BS are lower than the specified threshold voltage.

Output drivers typically source / sink 350mA / 650mA, respectively, which is suitable for three-phase half-bridge applications in motor drive systems.
