MM9Z1_638 Zero voltage and Zero Current

[a852013777]

Hi NXP partner

We use MM9Z1_638 to be battery junction box senor board.When we apply 0V and 0A to mm9z1_638 senor board A~H point which show test configuration file. We found mm9z1_638 report  is 0~1.2V and 0~0.1A through CANBUS. as attached file. How to etiminate the minor voltage and current when our voltage sensor point and current senor with 0V and 0A.

Hi Mike,

please refer to the AN12301. There is a possibility of VSENSE, ISENSE and TSENSE calibration. In the section 5. is the description of the system calibration procedure.
