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.
