FAN7888: 225V, 3.3/5V input logic compatible, 0.65/0.35A sink/source current, 3-Phase Half-Bridge Gate-Drive IC
Description: The FAN7888 is a monolithic three half-bridge gate...
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 VS = -9.8 V (typical) for VBS =15 V.
The UVLO circuits prevent malfunction when VDD and VBS 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.
