FAN7383
Half-Bridge Gate-Drive IC
Features
Description
„ Floating Channel Designed for Bootstrap Operation to
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.
„

„
+600V.
Typically 350mA/650mA Sourcing/Sinking Current
Driving Capability for Both Channels
Extended Allowable Negative VS Swing to -9.8V for
Signal Propagation at VDD=VBS=15V
High-Side Output in Phase of IN Input Signal
Built-in UVLO Functions for Both Channels
Built-in Common-Mode dv/dt Noise Canceling Circuit
Typically Internal 330nsec Minimum Dead Time
Programmable Turn-On Delay Time Control
(Dead Time)
Fairchild’s high voltage process and common-mode
noise canceling technique give stable operation of highside drivers under high-dv/dt noise circumstances.
An advanced level-shift circuit allows high-side gate
driver operation up to VS= -9.8V (typical) for VBS=15V.
The UVLO circuits for both channels prevent malfunction
when VDD and VBS 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.

1. Normal Operating Consideration
3. Layout Consideration
The FAN7383 is a single PWM input half-bridge gatedrive IC with programmable dead-time and shutdown
function.
For optimum performance of high- and low-side gate
drivers, considerations must be taken during
printed circuit board (PCB) layout.
The dead-time is set with a resistor(RDT) at the DT pin.
The wide dead-time programming range provides the
flexibility to optimize drive signal timing for a selection of
switching devices (MOSFET or IGBT) and applications.
3.1 Supply Capacitors
If the output stages are able to quickly turn on the
switching device with high value of current, the supply
capacitors must be placed as close as possible to the
device pins (VDD and GND for the ground-tied supply, VB
and VS for the floating supply) to minimize parasitic
inductance and resistance.
The turn-on time delay circuitry (Dead-Time)
accommodates resistor values from 0Ω to 200kΩ with a
dead-time proportional to the RDT resistance.
Grounding the DT pin programs the FAN7383 to drive
both outputs with minimum dead time.
3.2 Gate Drive Loop
If the SD pin voltage decreases below 1.2V in normal
operation, the IC enters the shutdown mode.
Current loops behave like an antenna, able to receive
and transmit noise. To reduce the noise coupling/
emission and improve the power switch turn-on and off
performances, gate drive loops must be reduced as
much as possible.
2. Under Voltage Lockout (UVLO)
The FAN7383 has an under-voltage lockout (UVLO)
protection circuitry for high and low side channels to
prevent malfunction when VDD or VBS is lower than the
specified threshold voltage. The UVLO circuitry monitors
the supply voltage (VDD) and bootstrap capacitor voltage
(VBS) indepently.
3.3 Ground Plane
Ground plane must not be placed under or nearby the
high-voltage floating side to minimize noise coupling.
