FAN7393
Half-Bridge Gate Drive IC
Features
Description
Floating Channel for Bootstrap Operation to +600V
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.
Typically 2.5A/2.5A Sourcing/Sinking Current Driving
Capability
Extended Allowable Negative VS Swing to -9.8V for
Signal Propagation at VBS=15V
High-Side Output in Phase of IN Input Signal
3.3V and 5V Input Logic Compatible
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 VS=-9.8V (typical) for
Matched Propagation Delay for Both Channels
Built-in Shutdown Function
Built-in UVLO Functions for Both Channels
Built-in Common-Mode dv/dt Noise Cancelling Circuit
Internal 370ns Minimum Dead Time at RDT=0 Ω
VBS=15V.
The UVLO circuit prevents malfunction when VDD and
VBS are lower than the specified threshold voltage.
Programmable Turn-on Delay Control
(Dead-Time)
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
