*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.
