Hi Team,

My customer is now evaluating INA381 for their application and some questions may need your confirmation, thanks.:

1. Is it the logic high & low threshold for RESET pin as well?

2.Do we have accuracy for Vs?[Supply voltage]

The Vih and Vil in the datasheet apply to the RESET pin as well.

If it's not spec'd in the datasheet then no. However, we do mention the Vs swing to supply and GND.

Thanks

Hi Frank,

We typically get this type of requests for automotive grade devices. Can you share more of why the customer is requesting this document? What is the application of the part?

Hi Frank,

TI only provides FMEA documentation for automotive grade devices. Here's the FMEA for the INA381-Q1 (automotive grade part).
