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.
