Hi TI,
According to customer's requirement, chassis will not connect to high voltage or low voltage GND.
Is it OK to modify the circuit from "Addendum to TIDA-01513" below?
If this modifiation is wrong, is there other way (or design guide) to meet customer's requirement?
One more question.
Why voltage measurement circuit need to to be isolated, but isolation leakage current or isolation resistance don't?
