MM8118W is a battery fuel gauge IC for Li-ion battery and Li-polymer battery. This IC achieves ultra-low power consumption. It is ideal for measuring the remaining battery power in wearable products with small battery capacity.
The small CSP package makes it ideal for compact products with a limited mounting area.
This IC measures temperature, voltage, and current using a high-precision delta-sigma AD converter, integrates current value both at discharging and charging and performs capacity correction based on the measured value and specific battery characteristics.
Thus the IC achieves excellent battery power management ability.
MM8118W provides several features to make battery use safe and secure :
- Battery degradation detection based on changes in battery capacity.
- Notification of these information.
MM8118W can be implemented either in the system itself or in the battery pack.
The MinebeaMitsumi lithium battery management circuits are made in Japan and are of the highest quality. They will be perfectly suited for your applications.
