3 to 5cells Li-ion/Li-polymer battery protection IC
MM3575 Series
Outline
The MM3575 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, charging overcurrent, cell balance and V5 to V3 pin disconnect
of the rechargeable 3 to 5cell Lithium-ion or Lithium-polymer battery can be detected. By using cascade
connection, it is also possible to protect 6 or more cells rechargeable Lithium-ion battery. And the regulator
can be constructed by using external Nch MOS FET. The internal circuit of IC is composed by the voltage
detector, the reference voltage source, delay time control circuit, and the logical circuit, etc.

(3) Protected operation can be detectof V5ꢃV1 pin disconnection
When any of V5 to V1 pin open, it will detect disconnection and charge and discharge prohibited state.
Protection mode of disconnection can be chosen from three, prohibition of charge, prohibition of discharge
and prohibition of charge and discharge (Optional)
The release from disconnection protection is done by disconnection point being connected.
(4) The setting for three cell, for four cell, and for five cell protection can be set with the SEL pin.
(5) The charge and discharge of the battery can be controlled with SDC pin and SOC pin.
(6) ꢀV battery charge function
Selection from "Prohibition" or "Permission"
(7) Power save mode built-in
It is possible to make it shift to low consumption current mode arbitrarily.
Transition of power save mode is used by SDC,SOC pins.
It shifts to a power save mode by making SDC and SOC pin into a VSS level.
