2 cells lithium-ion/lithium-polymer battery protection IC

MM3220 Series

Outline

MM3220 series are protection IC using high voltage CMOS process for overcharge, overdischarge and

overcurrent protection of the rechargeable Lithium-ion or Lithium-polymer battery.

The overcharge, overdischarge, discharging overcurrent, short, charging, and overcurrent(optional) of the

rechargeable one-cell Lithium-ion or Lithium-polymer battery can be detected. Each of these IC composed

of four voltage detectors, short detection circuit, reference voltage sources, oscillator, counter circuit and

logical circuits.

R1 , C1 , R2 , C2 stabilize a supply voltage ripple. However, R1 is enlarged, the detection voltage shifts

by voltage when current consumption ﬂows into R1. Please decide it after conﬁrming the characteristic.

Moreover, adjust the value of C1 , C2 to 0.01µF or more to do the stability operation, please.

R1 and R3 resistors are current limit resistance if a charger is connected reversibly or a high-voltage charger

that exceeds the absolute maximum rating is connected. R1 and R3 may cause a power consumption will

be over rating of power dissipation, therefore the `R1+R3` should be more than 1k . Moreover, if R3 is too

enlarged, the charger connection release cannot be occasionally done after the overdischarge is detected, so

adjust the value of R3 to 10k or less, please.

In the state of overdischarge, The current ﬂows through overdischarge pull-up resistance built into between

VDD terminal and V- terminal when the charger is connected. As a result, current that ﬂows into VDD terminal

increases. When current increases, the voltage is generated in R1. And hysteresis might be caused. Please

use it after conﬁrming the characteristic.

C3 and C4 capacitors have effect that the system stability about voltage ripple or imported noise. After

check characteristics, decide that these capacitors should be inserted or not, where should be inserted, and

capacitance value, please.
