Built-in UVLO Functions for All Channels

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 V S = -9.8 V (typical) for V BS =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 V DD and V BS 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.
