ISO5452: Driving two IGBTs in parallel

Mervin J B

Part Number: ISO5452

Can I drive two IGBTs in parallel using single driver IC? If yes, What is the recommended circuit connection with respect to OUTH, OUTL, CLAMP pins?

Hi, Mervin,

Yes, this is possible. Each IGBT should have it's own gate resistor located close to the IGBT itself.

And, the CLAMP pin should be used to drive PNP (or PMOS) on the gate of each IGBT to the Emitter.

Something like this:

Let us know if you have any further questions, Mervin.

Best regards,

Don
