Hi Eric,

We currently don’t have a similar device in production that satisfies both conditions. However the situation may change. If you can check back in a month or two, I may have a better answer.

Regards, Guang

Eric,

You could consider the isolated current sense amplifiers or if your current level is low enough, one of our in-package Hall-effect current sensors.
