The MM3280JA1YRE from MinebeaMitsumi is a protection IC utilizing high-voltage CMOS process for rechargeable Lithium-ion or Lithium-polymer batteries. It is designed to detect overcharge, overdischarge, discharging overcurrent, and short circuit conditions. Optional detection for charging overcurrent and over voltage charger conditions are also available.
This IC is composed of four voltage detectors, a short detection circuit, reference voltage sources, an oscillator, a counter circuit, and logical circuits. It supports a 0V battery charge function, which can be selected as either prohibition or permission. The device also features a reset function for the overcharge detection delay timer, suitable for pulse charging applications.
Key electrical specifications include a wide range of detection and release voltages for overcharge and overdischarge, with accuracies specified. It also offers various detection delay times for different fault conditions, including overcharge, overdischarge, discharging overcurrent, charging overcurrent, and short detection. The device operates with low current consumption in normal and standby modes.
The MM3280JA1YRE is available in SSON-6J and SOT-26AorB packages, suitable for surface mounting.
The overcharge detection voltage ranges from 3.6V to 5.0V with an accuracy of ±0.02V, and the overcharge release voltage ranges from 3.6V to 4.5V with an accuracy of ±0.03V.
The overdischarge detection voltage ranges from 2.0V to 3.0V with an accuracy of ±0.035V, and the overdischarge release voltage ranges from 2.0V to 3.5V with an accuracy of ±0.1V.
The normal mode current consumption is typically 3.0µA and has a maximum of 6.0µA.
The standby mode current consumption is a maximum of 0.1µA for charger connection release and a maximum of 0.5µA for voltage release.
The MM3280JA1YRE is available in SSON-6J and SOT-26AorB packages.
