1cell Li-ion/Li-polymer battery protection IC MM3724 Series

1cell Li-ion/Li-polymer battery protection IC

MM3724 Series

Outline

The MM3724 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 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 logical circuits.
