Description

The FAN73892 is a monolithic three-phase half-bridge

gate-drive IC designed for high-voltage, high-speed,

driving MOSFETs and IGBTs operating up to +600 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 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 350 mA and

650 mA, respectively; which is suitable for three-phase

half-bridge applications in motor drive systems.
