Features

(1) Internal high accuracy voltage detection circuit

? Overcharge detection voltage 3.900 V to 4.500 V (applicable in 5 mV step) Accuracy: ?25 mV (?25?C) and

?30 mV (?5?C to ?55?C)

? Overcharge hysteresis voltage 0.1 V to 0.4 V*1 Accuracy: ?25 mV

The overcharge hysteresis voltage can be selected from the range 0.1 V to 0.4 V in 50 mV step.

? Overdischarge detection voltage 2.000 V to 3.000 V (applicable in 10 mV step) Accuracy: ?50 mV

? Overdischarge hysteresis voltage 0.0 V to 0.7 V*2 Accuracy: ?50 mV

The overdischarge hysteresis voltage can be selected from the range 0.0 V to 0.7 V in 100 mV step.

? Overcurrent 1 detection voltage 0.050 V to 0.300 V (applicable in 10 mV step) Accuracy: ?15 mV

? Overcurrent 2 detection voltage 0.500 V (fixed) Accuracy: ?100 mV

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

(3) Delay times (overcharge: t CU, overdischarge: tDL , overcurrent 1: tlOV1 , overcurrent 2: tlOV2 ) are generated by an

internal circuit. No external capacitor is necessary. Accuracy: ?20%

(4) Three-step overcurrent detection circuit is included (overcurrent 1, overcurrent 2 and load short-circuiting).

(5) 0 V battery charge function “Available” / “Unavailable” is selectable.

(6) Power-down function “Yes” / “No” is selectable.

(7) Charger detection function and abnormal charge current detection function

? The overdischarge hysteresis is released by detecting negative voltage at the VM pin (?0.7 V typ.) (Charger

detection function).

? When the output voltage of the DO pin is high and the voltage at the VM pin is equal to or lower than the charger

detection voltage (?0.7 V typ.), the output voltage of the CO pin goes low (Abnormal charge current detection

function).

(8) Low current consumption

? Operation mode 3.5 ?A typ., 7.0 ?A max.

? Power-down mode 0.1 ?A max.

(9) Wide operating temperature range ?40?C to ?85?C

(10) Lead-free, Sn 100%, halogen-free*3
