Overview

MITSUMI 2 cells lithium-ion/lithium-polymer battery protection IC 2 cells lithium-ion/lithium-polymer battery protection IC MM3220 Series Outline MM3220 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, and overcurrent(optional) 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.

Key Features

  • (Unless otherwise specified, Topr=+25°C) (1) Range and accuracy of detection / release voltage Overcharge detection voltage 4.0V to 4.5V, 5mV steps Overcharge release voltage Overdischarge detection voltage Overdischarge release voltage Discharging overcurrent detection voltage 1 Discharging overcurrent detection.
