*1. Temperature coefficient for detection and release voltage is applied to overcharge detection voltage n, overcharge release voltage n, overdischarge
*2. Temperature coefficient for overcurrent detection voltage is applied to over current detection voltage 1 and 2.
*3. Since products are not screened at high and low temperature, the specification for this temperature range is guaranteed by design, not tested in
