The MM3280H02NRH series protection ICs from MinebeaMitsumi utilize high-voltage CMOS process technology for safeguarding rechargeable Lithium-ion and Lithium-polymer batteries. These ICs are capable of detecting and protecting against overcharge, overdischarge, discharging overcurrent, and short circuits. Optional detection for charging overcurrent and overvoltage charger conditions are also available.
Key electrical specifications include a wide range of detection and release voltages for overcharge (3.6V to 5.0V) and overdischarge (2.0V to 3.0V). Detection delay times are selectable, offering flexibility in design. The device operates with low current consumption, typically 3.0µA in normal mode and as low as 0.1µA in standby mode.
Packaged in a SOT-23-6 surface-mount package, the MM3280H02NRH is suitable for compact battery management systems. Its design incorporates voltage detectors, short detection circuits, reference voltage sources, oscillators, counter circuits, and logical circuits for robust battery protection.
This series is designed for one-cell battery applications, providing essential safety features for portable electronic devices. The selectable 0V battery charge function adds further design versatility.
