MM3511

MITSUMI One-cell li-ion/li-polymer battery protection IC One-cell li-ion/li-polymer battery protection IC MM3511 Series Outline MM3511 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, and short protection of the rechargeable onecell 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. Features (Unless otherwise specified, Topr=+25°C) 1.Range and accuracy of detection/release voltage Overcharge detection voltage 3.6V to 5.0V, 5mV steps Overcharge release voltage Overdischarge detection voltage Overdischarge release voltage Discharging overcurrent detection voltage Charging overcurrent detection voltage Short detection vol...
