Designed using a high-voltage CMOS process, MinebeaMitsumi ICs provide comprehensive protection for rechargeable Lithium-ion and Lithium-polymer batteries. They protect against overcharge, overdischarge, overcurrent during charging and discharging, as well as short circuits. They integrate four voltage detectors, a short-circuit detection circuit, reference voltage sources, an oscillator, a counter circuit, and logic circuits to ensure reliable and efficient battery protection. The MM3508C series are dual protection ICs designed for 2 to 3 cells lithium-ion or lithium-polymer battery packs, providing secondary protection. They detect overcharge voltage for each cell with high accuracy. The CT terminal is used to control the output voltage at the OV terminal.
MM3508C features :
- Range and accuracy of detection/release voltage
- Range of detection delay time
- Low current consumption
- Terminal CT used to control the output voltage of terminal OV
