1 to 4 cells lithium-ion/lithium-polymer battery Secondary protection IC
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
Typ. 2.5µA, Max. 5.0µA (Vcell=3.5V)
