2.0 Amp IGBT Gate Drive
Optocoupler with Integrated
Over-current Protection and
Fault Feedback
Preliminary Technical Data
HCPL-3160
Features
• Integrated IGBT
Desaturation Protection
• Integrated Optically Isolated
IGBT Fault Status Feedback
Description
The HCPL-3160 provides low cost,
area efficient IGBT gate drive
that includes desaturation or over
current detection and local IGBT
shutdown. The integrated fault
feedback optocoupler notifies
the controller when the IGBT is
shutdown due to a desaturation
or over current condition.
• CMOS Compatible INPUT
and FAULT Status Indicator

Fault Circuit Operation
controller of the IGBT fault by
bringing the FAULT output low.
The FAULT output remains
a single fault bus for interfacing
with the micro-controller. The
ENABLE input can also be
connected to this fault bus. With
this connection all IGBTs in a
drive are shutdown without
micro-controller intervention
once a fault is detected on a
single IGBT.
A typical desaturation protected
IGBT gate drive application
circuit using the HCPL-3160 is
shown in Figure 1. The IGBT
collector to emitter voltage
low until RESET is brought low.
(Note if a separate reset line
is not required, RESET can be
connected to Vin on the circuit
board. In this case, the FAULT
output will be reset on the next
PWM cycle that Vin goes low.)
The FAULT output is an open
collector which allows the FAULT
outputs from all the HCPL-3160s
in a drive to be connected
is monitored through DDESAT
.
When the IGPT is on and VDESAT
exceeds the internal reference
voltage of 7 V the IGBT gate is
“softly” turned-off by M2 to
prevent large di/dt generation.
The LED2 driver is also activated,
which drives the internal

detection circuitry for a time
period sufficient for normal IGBT
turn-on. CBLANK is held low by
