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 logical circuits.
