The MM3722KF2RRE from MinebeaMitsumi is a high-voltage CMOS process Lithium-Ion battery protection IC. It is engineered to detect and protect rechargeable Lithium-ion or Lithium-polymer batteries from overcharge, overdischarge, discharging overcurrent, charging overcurrent, and short circuits.
This IC features four voltage detectors, a short detection circuit, reference voltage sources, an oscillator, a counter circuit, and logical circuits. It detects charge and discharge currents with high precision using a current sensing resistor. The MM3722 series is designed for one-cell battery packs and offers high accuracy and temperature independence for over-current and short-current protection.
Key electrical specifications include adjustable overcharge detection voltage from 3.6V to 5.0V and overdischarge detection voltage from 2.0V to 3.0V. Various delay times are configurable for different protection events, ranging from microseconds for short detection to seconds for overcharge detection. The device also includes a selectable 0V battery charge function and operates with low current consumption in normal mode.
This protection IC is suitable for applications requiring robust battery management and safety features for Lithium-ion battery systems.

The overcharge detection voltage ranges from 3.6V to 5.0V with ±20mV accuracy. The overdischarge detection voltage ranges from 2.0V to 3.0V with ±35mV accuracy.
It offers protection against discharging overcurrent (20mV to 150mV detection voltage) and charging overcurrent (-150mV to -20mV detection voltage).
Delay times vary: overcharge detection is 256ms to 4.6s, overdischarge detection is 8ms to 256ms, discharging overcurrent detection is 8ms to 256ms, charging overcurrent detection is 6ms to 64ms, and short detection is 250µs to 400µs.
Yes, the 0V battery charge function is selectable and can be set to 'Permission' or 'Inhibition'.
The typical current consumption in normal mode is 3.0µA, with a maximum of 6.0µA.
