Description
The ACPL-312U device contains an AlGaAs LED. The LED
is optically coupled to an integrated circuit with a power
output stage. This wide operating temperature optocou-
pler is ideally suited for driving power IGBTs and MOSFETs
used in wide operating temperature motor control
inverter and DC-DC converters applications. The high
operating voltage range of the output stage provides the
drive voltages required by gate controlled devices. The
voltage and current supplied by these optocouplers make
them ideally suited for directly driving IGBTs with ratings
up to 1200 V/100 A. For IGBTs with higher ratings, the
ACPL-312U series can be used to drive a discrete power
stage which drives the IGBT gate.
Avago R²Coupler isolation products provide the rein-
forced insulation and reliability needed for critical in auto-
motive and high temperature industrial applications.
