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 +600V.
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
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
V
Output drivers typically source and sink 350mA and
650mA, respectively; which is suitable for three-phase
half-bridge applications in motor drive systems.
