Part Number: BQ77216
When I don't need all 16 cells of the BQ77216, how should I connect the inputs?

TI provides design resources and design advice (including technical, schematic, code and/or system review) “as is” and with all faults. All information in this or related correspondence is provided subject to TI’s Important Notice (http://www.ti.com/corp/docs/legal/important-notice.shtml).
Cell count for the BQ77216 is typically reduced by shorting the inputs starting at the top, see the BQ77216 data sheet figure 9-3 for an example with 14 cells. Cells which are below the VUV_MIN UV Detection Disabled Threshold in the section 7.5 DC Characteristics are not used for UV detection. Shorted cells also will not fault from OV or the open wire detection.
Cell inputs in the center of the stack can be shorted also. Cell 1 has a different open wire detection threshold since it operates at VSS, see the VOW OW Detection Threshold parameter. Shorting cell 1 is not recommended.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
