MinebeaMitsumi's fuel gauge ICs ensure safe and efficient use of batteries by accurately monitoring their charge level. MM8118G is a high-accuracy battery monitoring IC designed for Li-ion and Li-polymer batteries. It uses a high-precision delta-sigma A/D converter to measure temperature, voltage, and current, and integrates current value during both discharging and charging phases. By combining these measurements with specific battery characteristic parameters, it performs capacitance correction, enabling highly accurate battery management. MM8118G includes a range of features to make battery use safe and secure, including battery degradation detection based on changes in capacitance. It also provides notification functions to report battery status and anomalies. MM8118 can be implemented on both of host-side and battery-side.
MM8118G features :
- High accuracy current/voltage measurement
- High accuracy battery power management
- Battery degradation monitor
- Coulomb counting type
M8118G applications :
- Wearable devices
