MITSUMI

1 to 4 cells lithium-ion/lithium-polymer battery Secondary protection IC

MM3284 Series

Outline

MM3284 series are secondary protection IC using high voltage CMOS process for overcharge protection of

the rechargeable lithium-ion or lithium-polymer secondary battery. The high accuracy overcharge detection

of each cell of the rechargeable 1 to 4 serial cells lithium-ion or lithium-polymer secondary battery is possible.

With a timer circuit built-in, it is possible to set overcharge detection delay time.

(Unless otherwise speciﬁed, Topr=+25°C)

Features

1.Range and accuracy of overcharge detection/hysteresis voltage

Overcharge detection voltage

4.0V to 4.5V, 5mV step

Overcharge hysteresis voltage

50mV to 1000V, 50mV step

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
