2.5A Gate-Driver Optocoupler Simplifies IGBT Fault Protection

The ACPL-332J is a 2.5A output intelligent gate driver designed to simplify the implementation of compact IGBT collector-to-emitter voltage fault protection.

Avago’s 2.5A IGBT gate-driver optocoupler features integrated desaturation detection, fault-status feedback and active Miller clamping.

To provide circuit protection, the gate driver also integrates Under-Voltage LockOut (UVLO), soft IGBT turn-off and isolated open-collector fault feedback. Additionally, the ACPL-332J contains a GaAsP LED optically coupled to an integrated circuit with a power-output stage.

The voltage and current supplied by these optocouplers is suitable for directly driving IGBTs with ratings up to 1200V and 150A. For IGBTs with higher ratings, the ACPL-332J can be used to drive a discrete power stage, which then drives the IGBT gate.

Avago offers more than 20 of these gate-drive optocoupler products with outputs ranging from 0.2A (ACPL-P302) to 5A (ACNW3190).
