The MM3280J03NRH from MinebeaMitsumi is a high-voltage CMOS protection IC specifically designed for one-cell Lithium-ion and Lithium-polymer rechargeable batteries. This integrated circuit provides essential protection functions including overcharge, overdischarge, discharging overcurrent, and short circuit detection.
Key electrical specifications include a range of detection and release voltages for overcharge (3.6V to 5.0V detection, 3.6V to 4.5V release) and overdischarge (2.0V to 3.0V detection, 2.0V to 3.5V release). It also features detection voltages for discharging overcurrent (+50mV to +300mV) and charging overcurrent (-300mV to -50mV), as well as short detection voltages (0.7V, 0.8V, 0.9V). The device offers various detection delay times for different protection events, ranging from microseconds to seconds.
With low current consumption in normal mode (typ. 3.0µA) and stand-by mode (max. 0.1µA or 0.5µA depending on release condition), the MM3280J03NRH is suitable for power-sensitive applications. It is available in a SOT-23-6 package, suitable for surface-mount assembly.
Optional features include over-voltage charger detection and release, and a 0V battery charge function that can be set to prohibition or permission. The device also includes a function to reset the overcharge detection delay timer, useful for pulse charging applications.
The overcharge detection voltage is programmable from 3.6V to 5.0V in 5mV steps with an accuracy of ±20mV.
The overdischarge detection voltage is programmable from 2.0V to 3.0V in 50mV steps with an accuracy of ±35mV.
The MM3280J03NRH is available in a SOT-23-6 package.
The typical current consumption in normal mode is 3.0µA, with a maximum of 6.0µA.
Yes, the MM3280J03NRH supports a 0V battery charge function, which can be selected as either permission or prohibition.
