MITSUMI One-cell lithium-ion/lithium-polymer battery protection IC One-cell lithium-ion/lithium-polymer battery protection IC MM3280 Series Outline MM3280 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 overcurrent (optional), and over voltage charger (optional) protection 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 log...
