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 applica-
tions. 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 5 kV/µs
typical these optocouplers 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.
