FAN73892 3-Phase Half-Bridge Gate-Drive IC

The FAN73892M is a monolithic three-phase half-bridge gate-drive IC designed for high-voltage, high-speed, driving MOSFETs and IGBTs operating up to +600V.

ON Semiconductor’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 protection functions include under-voltage lockout and inverter over-current trip with an automatic fault-clear function. Over-current protection that terminates all six outputs can be derived from an external current-sense resistor. An open-drain fault signal is provided to indicate that an over-current or under-voltage shutdown has occurred. The UVLO circuits prevent malfunction when VDD and VBS are lower than the threshold voltage.

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