The V_empty register sets thresholds related to empty
detection during operation.
register format.
VE
detecting empty. A 10mV resolution gives a 0 to 5.11V
range. This value is written to 3.12V at power-up.
VR
clearing empty detection. Once the cell voltage rises
above this point, empty voltage detection is reenabled.
A 40mV resolution gives a 0 to 5.08V range. This value is
written to 3.68V at power-up.
Proper cell characterization is required to achieve accu-
racy. The following registers
that must be generated through a cell-characterization
procedure. Maxim provides a cell-characterization ser-
vice. Contact the factory for details.
