Ordering Information
Description
The FAN7393A is a half-bridge gate-drive IC with shut-
down and programmable dead-time control functions
that can drive high-speed MOSFETs and Isolated Gate
Bridge Transistors (IGBTs) operating up to +600V. It has
a buffered output stage with all NMOS transistors
designed for high-pulse-current driving capability and
minimum cross-conduction.
Fairchild’s high-voltage process and common-mode
noise canceling techniques provide stable operation of
the high-side driver under high dv/dt noise circum-
stances. An advanced level-shift circuit offers high-side
gate driver operation up to V S =-9.8V (typical) for
V BS =15V.
The UVLO circuit prevents malfunction when V DD and
V BS are lower than the specified threshold voltage.
The high-current and low-output voltage drop feature
makes this device suitable for diverse half- and full-
bridge inverters; motor drive inverters, switching mode
power supplies, induction heating, and high-power DC-
DC converter applications.
