ACPL-331J

1.5 Amp Output Current IGBT Gate Driver Optocoupler

Fault Status Feedback and Active Miller Clamping

Data Sheet

Description

The ACPL-331J is an advanced 1.5 A output current, easy-

to-use, intelligent gate driver which makes IGBT VCE fault

protection compact, affordable, and easy-to implement.

voltage lockout (UVLO), “soft” IGBT turn-off, isolated

open collector fault feedback and active Miller clamping

provide maximum design flexibility and circuit protec-

tion.

The ACPL-331J contains a GaAsP LED. The LED is optically

coupled to an integrated circuit with a power output

stage. ACPL-331J is ideally suited for driving power IGBTs

and MOSFETs used in motor control inverter applications.

The voltage and current supplied by these optocouplers

make them ideally suited for directly driving IGBTs with

ratings up to 1200 V and 100 A. For IGBTs with higher

ratings, the ACPL-331J can be used to drive a discrete

power stage which drives the IGBT gate. The ACPL-331J
