Description
The HCPL-3150 consists of a
GaAsP LED optically coupled to
an integrated circuit with a power
output stage. This optocoupler is
ideally suited for driving power
IGBTs and MOSFETs used in
motor control inverter applica-
tions. The high operating voltage
range of the output stage pro-
vides the drive voltages required
by gate controlled devices. The
voltage and current supplied by
this optocoupler makes it ideally
suited for directly driving IGBTs
with ratings up to 1200 V/50 A.
For IGBTs with higher ratings,
the HCPL-3120 can be used to
drive a discrete power stage
which drives the IGBT gate.
