High-withstand voltage (VM pin and CO pin: Absolute maximum rating = 28 V)

0 V battery charge function “available” / “unavailable” is selectable.

Power-down function “available” / “unavailable” is selectable.

Wide operating temperature range

Ta = -40°C to +85°C

Low current consumption

During operation: 2.8 µA typ.,5.0 µA max. (Ta = +25°C)

During power-down: 0.1 µA max. (Ta = +25°C)

Lead-free (Sn 100%), halogen-free

*1. Overcharge release voltage = Overcharge detection voltage – Overcharge hysteresis voltage
Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV steps.)
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
Overdischarge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV steps.)
