*1. Auxiliary overcharge detection voltage is equal to the overcharge detection voltage times 1.11 for the
*2. Temperature coefficient 1 for detection voltage should be applied to overcharge detection voltage,
*3. Temperature coefficient 2 for detection voltage should be applied to overcurrent detection voltage.
*4. The DO pin and CO pin logic are established at the operating voltage.
