Description
The HCPL-3000 consists of a
Silicon-doped GaAs LED optically
coupled to an integrated circuit
with a power output stage. This
optocoupler is suited for driving
power bipolar transistors and
power Darlington devices used in
motor control inverter applica-
tions. The high peak and steady
state current capabilities of the
output stage allow for direct
interfacing to the power device
without the need for an interme-
diate amplifier stage. With a CMR
rating of 1.5 kV/碌s this optocoup-
ler readily rejects 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 base 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 to drive
the base of a power bipolar
device.

THE USE OF A 0.1碌F BYPASS CAPACITOR CONNECTED BETWEEN PINS 8 AND 7 IS RECOMMENDED. ALSO, CURRENT LIMITING
RESISTORS ARE RECOMMENDED (SEE FIGURE 1, NOTE 2, AND NOTE 7).
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to
prevent damage and/or degradation which may be induced by ESD.
