Description

The ACPL-333J is an advanced 2.5 A output current, easy-

protection compact, affordable, and easy-to implement.

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

collector fault feedback, active Miller clamping and Auto-

fault reset provide maximum design flexibility and circuit

protection.

The ACPL-333J contains a AlGaAs LED. The LED is optically

coupled to an integrated circuit with a power output

stage. ACPL-333J are 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 150 A. For IGBTs with higher

ratings, the ACPL-333J can be used to drive a discrete

power stage which drives the IGBT gate. The ACPL-333J
