*1. Since products are not screened at high and low temperature, the specification for this temperature range is
*2. Auxiliary overcharge detection voltage is equal to the overcharge detection voltage times 1.11 for the
*3. Temperature coefficient 1 for detection voltage should be applied to overcharge detection voltage,
*4. Temperature coefficient 2 for detection voltage should be applied to overcurrent detection voltage.
*5. The DO pin and CO pin logic are established at the operating voltage.
