ACPL-P341 and ACPL-W341
3.0 Amp Output Current IGBT Gate Drive Optocoupler
with Rail-to-Rail Output Voltage in Stretched SO6
Data Sheet
Description
Features
The ACPL-P341/W341 contains an AlGaAs LED, which is 3.0 A maximum peak output current
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
2.5 A minimum peak output current
Rail-to-rail output voltage
applications. The high operating voltage range of the 200 ns maximum propagation delay
output stage provides the drive voltages required by gate
controlled devices. The voltage and high peak output
current supplied by this optocoupler make it ideally
100 ns maximum propagation delay difference
LED current input with hysteresis
suited for direct driving IGBT with ratings up to 1200 V 35 kV/s minimum Common Mode Rejection (CMR) at
/ 100 A. For IGBTs with higher ratings, this optocoupler
can be used to drive a discrete power stage which drives
the IGBT gate. The ACPL-P341 and ACPL-W341 have the
