The overcharge hysteresis voltage can be selected from the range 0.0 V to 0.4 V in 50 mV step.
*1. Overcharge release voltage= Overcharge detection voltage − Overcharge hysteresis voltage
The overdischarge hysteresis voltage can be selected from the range 0.0 V to 0.7 V in 100 mV step.
*2. Overdischarge release voltage= Overdischarge detection voltage + Overdischarge hysteresis voltage
