Package
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 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
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.
