MM8013

MITSUMI Lithium-ion battery charge control IC MM8013 Lithium-ion battery charge control IC Monolithic IC MM8013 Outline The MM8013 is a high accuracy fuel gauge IC for 1-cell Li-ion battery or Li-polymer battery. The MM8013 measures temperature, voltage and current by high-precision delta-sigma AD converter and executes current integration both at discharging and charging using specific battery characteristics parameter and the measurement values. The MM8013 offers excellent management ability for battery power. The MM8013 achieves safety and security by following functions: battery degradation detection using capacitance change, anomaly detection. Features (1) High accuracy battery power management Battery power is based on current integration value which is measured periodically and is controlled to minimize its error by correction using open voltage (OCV) and battery characteristics parameter. (2) High precision voltage measurement Electric current and voltage value are measu...
