*1. Temperature coefficient 1 for detection voltage should be applied to overcharge detection voltage, overcharge release voltage,

overdischarge detection voltage, and overdischarge release voltage.

*2. Temperature coefficient 2 for detection voltage should be applied to overcurrent detection voltage.

*3. The DO and CO pin logic are established at the operating voltage.
