The MM3725/MM3726 Series from MinebeaMitsumi includes the MM3725AC3YRE, a protection IC for rechargeable Lithium-ion or Lithium-polymer batteries. This IC is built using a high voltage CMOS process and is designed to detect and protect against overcharge, overdischarge, discharging overcurrent, charging overcurrent, and short circuits.
Key electrical features include a range of detection voltages for overcharge (3.6V to 5.0V) and overdischarge (2.0V to 3.0V), with specific accuracy levels for each. It also offers detection ranges for discharging overcurrent (20mV to 300mV) and charging overcurrent (-300mV to -20mV), as well as short detection voltage (70mV to 350mV).
The device incorporates detection delay times for various conditions, such as overcharge detection delay from 256ms to 4.6s, and short detection delay from 250µs to 400µs. It is suitable for one-cell battery applications and comprises four voltage detectors, a short detection circuit, reference voltage sources, an oscillator, a counter circuit, and logical circuits.
This protection IC is essential for ensuring the safe operation and longevity of lithium-ion battery packs in various electronic devices.
