Fuel Gage IC for Li-ion Battery

MM8118 is a high accuracy battery monitoring IC for Li-ion battery and Li-polymer battery.This IC measures temperature, voltage, and current with high-precision delta-sigma AD converter, integratescurrent value both at discharging and charging, and performs capacitance correction based on the measurementvalue and specific battery characteristics parameter. Thus the IC achieves excellent management ability for batterypower.
MM8118 provides several features to make battery use safe and secure. Battery degradation detection which isbased on capacitance change is available. And this IC has features for notification of these information.
MM8118 can be implemented at both of host-side and battery-side.
