*1.

± 50 mV when Ta = −40°C to +85°C.

*2.

0.25

± 0.07 V, 0.13 ± 0.04 V, 0.045 ± 0.02 V except for 0.38 V hysteresis models.

*3.

Overcharge detection voltage or overcharge hysteresis voltage.

*4.

Since products are not screened at high and low temperature, the specification for this temperature range is guaranteed

by design, not tested in production.

*5.

After detecting the overcharge, the delay circuit operates normally in the range of operating voltage.

*6.

Output logic and CMOS or open drain output can be selected.
