Description

The FAN7389 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 faultclear

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 specified 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.
