MM4128A-4129A

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 MM4128A / MM4129A series are dual protection ICs designed for 2-cell lithium battery packs. They monitor the voltage of each individual cell and allow configurable delay times. Upon fault detection, the output signal can be maintained for a fixed duration, ensuring a consistent disconnection time for the fuse. Additionally, the IC's discharge function helps reduce high cell voltage after fuse disconnection, preventing battery degradation by stopping the voltage at a safe level.

MM4128A-MM4129A features :

• Range and accuracy of detection/release voltage
• Range of detection delay time
• Range of internal regulator voltage
• Low current consumption
