*1. Since products are not screened at high and low temperature, the specification for this temperature range is guaranteed
by design, not tested in production.
*2. −0.390 ±0.160 V, −0.260 ±0.110 V, −0.130 ±0.060 V, or none, except for −0.520 V hysteresis product circuits. The
overcharge release voltage is the total of the overcharge detection voltage (VCUn) and the overcharge hysteresis voltage
(VHCn).
