Description
The HCPL-3100/3101 consists of an
LED* optically coupled to an
integrated circuit with a power
output stage. These optocouplers
are suited for driving power
MOSFETs and IGBTs used in motor
control inverter applications. The
high operating voltage range of the
output stage provides the voltage
drives required by gate controlled
devices. The voltage and current
supplied by these optocouplers
allow for direct interfacing to the
power device without the need for
an intermediate amplifier stage.
The HCPL-3100 switches a
3000 pF load in 2
µs
and the
HCPL-3101, using a higher speed
LED, switches a 3000 pF load in
0.5
µs.
With a CMR rating of
15 kV/µs typical these opto-
couplers readily reject transients
found in inverter applications.
The LED controls the state of the
output stage. Transistor Q2 in the
output stage is on with the LED
off, allowing the gate of the power
device to be held low. Turning on
the LED turns off transistor Q2
and switches on transistor Q1 in
the output stage which provides
current and voltage to drive the
gate of the power device.

Recommended Protection for Output
Transistors
During switching transitions, the
output transistors Q1 and Q2 of
the HCPL-3100/3101 can
conduct large amounts of
current. Figure 1 describes a
recommended circuit design
showing a current limiting
resistor R
2
which is necessary in
order to prevent damage to the
output transistors Q1 and Q2.
(See Note 7.) A bypass capacitor
C
1
is also recommended to
reduce power supply noise.
