• High-accuracy voltage detection circuit
Overcharge detection voltage 3.9 V to 4.5 V (5 mV step) Accuracy ±25 mV (Ta = +25°C)
Accuracy ±30 mV (Ta = −5°C to +55°C)
Overcharge release voltage 3.8 V to 4.43 VP
*1
PAccuracy ±50 mV
Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step) Accuracy ±50 mV
Overdischarge release voltage 2.0 V to 3.4 VP
*2
PAccuracy ±100 mV
Discharge overcurrent detection voltage 0.05 V to 0.30 V (10 mV step) Accuracy ±15 mV
Load short-circuiting detection voltage 0.5 V (fixed) Accuracy ±200 mV
Charge overcurrent detection voltage −0.1 V (fixed) Accuracy ±30 mV
• Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
Accuracy ±20%
• High-withstand voltage device is used for charger connection pins
(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 operation temperature range Ta = −40°C to +85°C
• Low current consumption
During operation 3.0 μA typ., 5.5 μA max. (Ta = +25°C)
During power-down 0.2 μA max. (Ta = +25°C)
