T63H0008A

` High voltage device is used for charger connection pins V- and COUT pins: Maximum 30V
` 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.)
` 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%
` Three-step over-current detection circuit is included. (over-current 1, over-current 2, and load short-circuiting).
` Either charge function or charge inhibition function for 0V battery can be selected.
` 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)
` Low current consumption .
1.Operation 3.0uA typ. 7.0uA max.(IDD).
2.Power-down 0.1 uA max.(ISB).
` Wide operating temperature range: -40ºC to +85ºC
` Ultra Small package .........SOT-23-6 (6 PIN),SNB(B)(6PIN). (SNB Type please contact Sales).
