Features

l

High voltage device is used for charger connection pins V- and COUT pins: Maximum

30V

l

Internal high accuracy voltage detection circuit

1.Overcharge detection voltage 3.9V to 4.4V (applicable in 5mV step)

Accuracy : ±25mV (+25ºC) and ±30mV (-5ºC to +55ºC)

2.Overcharge hysteresis voltage 0.0V to 0.4V …………………………………….Accuracy : ±25mV

The overcharge hysteresis voltage can be selected from the range 0.0V to 0.4V in 50mV step.

3.Over-discharge detection voltage 2.0V to 3.0 V (10mV step) ………………….Accuracy : ±50mV.

4.Over-discharge hysteresis voltage 0.0V to 0.7 V (*2) ………………………….Accuracy : ±50mV

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

5.Overcurrent 1 detection voltage 0.05V to 0.3V (10mV step)……………………Accuracy : ±15mV

6.Overcurrent 2 detection voltage 0. 5V (fixed) …………………………………..Accuracy : ±100mV

*1: Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis voltage

(where overcharge release voltage<3.8V is prohibited.)

*2: Over-discharge release voltage = Over-discharge detection voltage + Over-discharge hysteresis voltage

(where over-discharge release voltage>3.4V is prohibited.)

l

Delay times

(overcharge: tVDET1, over-discharge: tVDET2,

over-current 1: tVDET3, over-current 2: t VDET4)

are generated by an internal circuit. No external capacitor is necessary. …………….Accuracy: ±20%

l

Three-step over-current detection circuit is included.

(over-current 1, over-current 2,

and load short-circuiting).

l

Either charge function or charge inhibition function for 0V battery can be selected.

l

Charger detection function and abnormal charge current detection function

1.The over-discharge hysteresis is released by detecting negative voltage at the V- pin (-0.7V typ.).

(Charger detection function)

2.When the output voltage of the DOUT pin is high and the voltage at the V- pin is equal to or lower than

the charger detection voltage (-0.7V typ.), the output voltage of the COUT pin goes low.

(Abnormal charge current detection function)

l

Low current consumption .

1.Operation 3.0uA typ. 7.0uA max.(IDD).

2.Power -down 0.1 uA max.(ISB).

l

Wide operating temperature range: -40ºC to +85ºC

l

Ultra Small package …………………..SOT-23-6 (6 PIN),SNB(B)(6PIN).
