The MM3280J04NRH from MinebeaMitsumi is a high-voltage CMOS protection IC for one-cell rechargeable Lithium-ion or Lithium-polymer batteries. It provides comprehensive protection against overcharge, overdischarge, discharging overcurrent, and short circuits. Optional protection against charging overcurrent and overvoltage charger conditions is also available.
Key electrical specifications include a wide range of detection and release voltages for overcharge and overdischarge conditions, with high accuracy. The IC also features selectable detection delay times for various fault conditions, including overcharge, overdischarge, discharging overcurrent, and charging overcurrent. It supports a 0V battery charge function, which can be set to prohibition or permission.
With low current consumption in normal and stand-by modes, the MM3280J04NRH is suitable for power-sensitive applications. It is supplied in a compact SOT-23-6 package, making it ideal for space-constrained designs. The device integrates voltage detectors, a short detection circuit, reference voltage sources, an oscillator, a counter circuit, and logic circuits for robust battery management.
This protection IC is designed to enhance the safety and longevity of battery packs in various electronic devices. Its precise voltage and current monitoring capabilities ensure reliable operation and prevent damage due to abnormal conditions.
