*1. Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis voltage
(Overcharge hysteresis voltage n (n = 1, 2) can be selected as 0 V or
from a range of 0.10 V to 0.40 V in 50 mVsteps.)
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n (n = 1, 2) can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mVsteps.)
