Automotive 2.5 Amp Output Current IGBT Gate Drive Optocoupler

Currently Viewing:

The ACPL-312T automotive optocoupler  contains an AlGaAs LED that is is optically coupled to an integrated circuit with a power output stage.

This automotive optocoupler is ideally suited for driving power IGBTs and MOSFETs  in automotive motor control inverter and DC-DC converter 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-312T series can be used to drive a discrete power stage which drives the IGBT gate.
