HCPL-3100, HCPL-3101
Power MOSFET/IGBT Gate Drive Optocouplers
Data Sheet
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.
