The pack voltage at which the PS401 will
enter Low Voltage SLEEP mode.
(entry due to low voltage and Sample
mode), there are four methods for waking
up. They are voltage level, current level,
SMBus activity and I/O pin activity. This
value defines which wake-up functions are
enabled, and also the voltage wake-up
level. The table below indicates the
appropriate setting. Note that the setting is
independent of the number of cells or their
configuration.
