One-cell li-ion/li-polymer battery protection IC
One-cell li-ion/li-polymer battery protection IC
MM3638 Series
Outline
MM3638 series are protection IC for lithium-ion and lithium-polymer battery. MM3638 protects the battery
pack from overcharge, overdischarge, and overcurrent, etc. by controlling FET SW. In the One-cell battery
pack, on resistance of the FET SW has been used for overcurrent detection. MM3638 realize overcurrent
protection with high accuracy and with no temperature dependence by using a chip resistor.

· R1 and C1 stabilize a supply voltage ripple. However, the detection voltage rises by the current of
penetration in IC of the voltage detection when R1 is enlarged, and the value of R1 is adjusted to 1k or
less. Moreover, adjust the value of C1 to 0.01µF or more to do the stability operation, please.
· R1 and R± 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 R± may cause a power consumption will
be over rating of power dissipation, therefore the `R1+R±` should be more than 1k . Moreover, if R± is too
enlarged, the charger connection release cannot be occasionally done after the overdischarge is detected,
so adjust the value of R± to 10k or less, please.
· R3 is resistor to sense the discharge or charging current. R3 is shown by the following expression by
discharging current IODCP, discharging overcurrent detection voltage Vdet3, charging current IOCCP, and
charging overcurrent detection voltage Vdet4.
IODCP=Vdet3/R3 IOCCP=Vdet4/R3
If R3 is too enlarged, the power loss increases. Moreover, the power might exceed a dissipation of resistance
by the overcurrent, please select R3 according to the cell spec, after confirming the characteristic.
· C±, 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. Please arrange C4 near the terminal and use a few uF from tens of pF.
