How to set the voltage resolution of MMZ1_638?

[bigbirdwyf]

Hi, everyone!  I find there are 3 voltage resolutions,i.e.,1mv,0.5mv,0.25 mv  from the  demo program in the RD9Z1-638-12V Reference Design.But I don't find how to set the voltage resolutions in MMZ1_638's registers.

Could you please help me ?

Thanks a lot!

Hi,

The MM9Z1J638 has four voltage measurement channels called VSENSE[3..0] with the following fixed resolutions:

In the RD9Z1-638-12V, only the VSENSE2 pin is used to measure the battery voltage and its resolution is 0.5mV:

Best regards,
