Hi Watanabe,

Let me check with the team and get back to you. What is the application use case and end equipment? Is there any target current monitor accuracy at 1A?

Best Regards,
Rakesh

Hello Rakesh-san,
We would like the accuracy less than 7.5%, better than TPS259541.

Hi Watanabe,

We did a limited sample testing (10#) below 2A up to 1A. The current monitor accuracy dropped to 5% at 1A.
Please let us know the importance of accuracy from application use point of view.

Best Regards,
Rakesh
