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.
