Description
The FAN7393 is a half-bridge, gate-drive IC with shut-
down and programmable dead-time control functions
that can drive high-speed MOSFETs and IGBTs operat-
ing up to +600V. It has a buffered output stage with all
NMOS transistors designed for high-pulse-current driv-
ing 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.
Applications
High-Speed Power MOSFET and IGBT Gate Driver
Induction Heating
High-Power DC-DC Converter
Synchronous Step-Down Converter
Motor Drive Inverter
