Typical Application Information
1. Normal Operating Consideration
The FAN73832 is a single PWM input, half-bridge, gate-
drive IC with programmable dead-time and shutdown
functions.
The dead-time is set with a resistor (R
DT
) at the DT/SD
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.
The
accommodates resistor values from 20k
Ω
to 200k
Ω
with
a dead-time proportional to the R
DT
resistance.

circuitry
(Dead-Time)
If the DT/SD pin voltage decreases below 1.2V in the
normal operation, the IC enters shutdown mode.
The external dead-time setting resistor (R
DT
) is at least
above 20K
Ω
for normal operation in typical applications.
2. Under Voltage Lockout (UVLO)
The FAN73832 has an under-voltage lockout (UVLO)
protection circuit for high- and low-side channels to
prevent malfunction when V
DD
and V
BS
are lower than
the specified threshold voltage. The UVLO circuitry
monitors the supply voltage (V
DD
) and bootstrap
capacitor voltage (V
BS
) indepently.
3. Layout Consideration
For optimum performance of the high- and low-side gate
drivers, considerations must be taken during printed
circuit board (PCB) layout.
3.1 Supply Capacitors
If the output stages are able to quickly turn-on a
switching device with a high value of current, the supply
capacitors must be placed as close as possible to the
device pins (V
DD
and GND for the ground-tied supply, V
B
and V
S
for the floating supply) to minimize parasitic
inductance and resistance.
3.2 Gate Drive Loop
Current loops behave like an antenna, able to receive
and transmit noise. To reduce the noise coupling/emis-
sion and improve the power switch turn-on and off per-
formances, gate drive loops must be reduced as much
as possible.
3.3 Ground Plane
Ground plane must not be placed under or nearby the
high-voltage floating side to minimize noise coupling.
