*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. −0.39 ±0.16 V, −0.26 ±0.11 V, −0.13 ±0.06 V, or none, except for −0.52 V hysteresis product circuits. The overcharge
release voltage is the total of the overcharge detection voltage (VCUn) and the overcharge hysteresis voltage (VHCn).
