MC33771 Unused Cell Inputs

How do you terminate unused cell inputs on the MC33771 AFE? The device supports 7-14 cells, but for fewer than 14 cells, how should the extra inputs be connected (e.g. shorted across the cell input or left floating)? And is there an order in which cell inputs should not be used?

Hi,

I don't know which version of your datasheet reference,but you can search 'unused' in datasheet you can find the related figure about the unused configuration.

Thanks!

Thank you G.w. Sun.

I was able to find the information in the long-form datasheet available through the NXP Docstore. The datasheet on the part's website is abbreviated and does not include this information.

In the datasheet MC33772B version5 page112-13.2.2 Unused cells,you can find!
