Hi,

Is there single event latchup data available for the DRV2700?

Hi,

Is there a specific latch-up event you are seeing with DRV2700?

Does this E2E post help?

No, I am considering designing this into a system that will go into low earth orbit, and was wondering if you had any radiation testing data, information on immunity to single event latchup, and/or any schematics on the output stage of the amplifier, as it's just represented as a triangle in the datasheet.

Hi Kilian, thanks for the clarification.

This was designed for the PE market. I have not seen rad hard data or anything related to SEL. This device has a class-AB output stage. I'm not sure how helpful that is. Sharing more on the internal schematic may require an NDA.

We have a Space team at TI that looks into TI's products for space applications. Have you had any contact with them? I can try to connect you with them if needed. That would be the best path forward because I don't think anyone in my Audio and Haptics team can help here.
