*1. The overcharge detection voltage n (n = 1 to 3) and overdischarge detection voltage (n = 1 to 3) cannot be selected if the voltage difference between them is 0.6 V or lower.

*2. Overcharge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV step. (Overcharge hysteresis voltage = Overcharge detection voltage − Overcharge release voltage)

*3. Overdischarge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.2 V to 0.7 V in 100 mV step. (Overdischarge hysteresis voltage = Overdischarge release voltage − Overdischarge detection voltage)

*4. The discharge overcurrent detection voltage and load short-circuiting detection voltage cannot be selected if the voltage difference between them is 0.3 V or lower.
