MM3508C series is a double protection IC for 2-4 cell Li batteries.
It detects battery voltage for each cell.
The terminal CT is used to control the output voltage of the terminal OV.

1. Range and accuracy of overcharge detection/hysteresis voltage

●Overcharge detection voltage	4.0V to 4.5V, 5mV step	Accuracy±20mV (Topr=0 to +50°C)
●Overcharge hysteresis voltage	50mV to 500mV, 50mV step	Accuracy±20%

2. Range of detection delay time

●Overcharge detection delay time	1ms to (1ms×2n1)+(1ms×2n2)
	*n1 and n2 can select two arbitrary integers between 0 to 13. (However n1≠n2)

3. Low current consumption

Typ. 3.0µA, Max. 5.0µA (Vcell=4.0V)
Typ. 2.5µA, Max. 4.0µA (Vcell=2.3V)

4. Absolute maximum ratings

●VDD pin	VSS-0.3 to VSS+28V
●OV pin	VSS-0.3V to VDD+0.3V
●Storage temperature	-55 to +125°C
●Operation temperature	-40 to +110°C

5. The terminal CT is used to control the output voltage of the terminal OV.
