MM3575

MITSUMI 3 to 5cells Li-ion/Li-polymer battery protection IC MM3575 Series 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. Features (Unless otherwise specified, Topr=+25°C) (1) Range and accuracy of detection/release voltage Overcharge detection...
