FAN7383 Half-Bridge Gate-Drive IC
February 2007
FAN7383
Half-Bridge Gate-Drive IC
Features
Floating Channel Designed for Bootstrap Operation to
+600V.
Typically 350mA/650mA Sourcing/Sinking Current
Driving Capability for Both Channels
Extended Allowable Negative V
S
Swing to -9.8V for
Signal Propagation at V
DD
=V
BS
=15V
High-Side Output in Phase of IN Signal
Built-in UVLO Functions for Both Channels
Built-in Common-Mode dv/dt Noise Canceling Circuit
Typically Internal 330ns Minimum Dead-Time
Programmable Turn-On Delay Time Control
(Dead-Time)
Description
The FAN7383 is a half-bridge gate-drive IC with
shutdown and programmable dead-time control
functions for driving MOSFETs and IGBTs that operate
up to +600V.
Fairchild’s high voltage process and common-mode
noise canceling technique give 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
S
= -9.8V (typical) for V
BS
=15V.
The UVLO circuits for both channels prevent malfunction
when V
DD
and V
BS
are lower than the specified
threshold voltage.
Output drivers typically source/sink 350mA/650mA,
respectively, which is suitable for all kinds of half and full
bridge inverter.
