[Outline]

This IC are secondary protection IC using high voltage CMOS process for overcharge protection of the rechargeable Lithium-ion or Lithium-polymer battery.
The high accuracy overcharge detection of each cell of the rechargeable 1-3-cell Lithium-ion or Lithium-polymer battery is possible. Each of these IC composed of four voltage detectors, reference voltage sources, oscillator, counter circuit and logical circuits.The ultra-small package SSON-6A is used to minimize footprints.

[Features]

1.	Range and accuracy of overcharge detection/hysteresis voltage
	·	Overcharge detection voltage
		4.0V to 4.5V, 5mV step	Accuracy±25mV (Topr=0~+60℃)
	·	Overcharge hysteresis voltage
		-500mV to -50mV	Accuracy±50mV to 100mV
2.	Range of Overcharge 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
