ACPL-T350
2.5 Amp Output Current IGBT Gate Driver Optocoupler with Low I
CC
Data Sheet
Description
The ACPL-T350 contains a GaAsP LED. The LED is optically
coupled to an integrated circuit with a power output
stage. These optocouplers are ideally suited for driving
power IGBTs and MOSFETs used in motor control inverter
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-T350 series can
be used to drive a discrete power stage whichs drives the
IGBT gate. The ACPL-T350 has an insulation voltage of
V
IORM
= 630 Vpeak (Option 060).
