DRV8143-Q1: ITRIP Regulation causes OTP fault

Part Number: DRV8143-Q1

Tool/software:

Hi Team,

I'm trying to use the ITRIP regulation function on the device however after reaching the trip current, the device oscillates for a brief time and then shuts off due to over temperature. As you can see from the image the peak current is 22A however the ITRIP current is 7.5A, the device senses this value but reacts to it very slowly. What might be the issue causing this regulation current to reach peak 22A values? How can I fix it?

Regards

Baris
