We are using the BOD reset level 3 (assertion 2.6V) as a battery check.  I had attempted to calculate the expected tolerance band on the 2.6V threshold using the internal voltage reference tolerance given in datasheet table 21.  However, after measuring several units I see the BOD triggering over a much wider range of voltages than I’d expect based on this data alone (2.57-2.69V seen in a sample of 13 units).

 

Do you have information on the expected range of BOD voltages at 25C and over temperature (our temperature range is 5C to 40C)?
