CW2015CHBD Fuel Gauge IC with Low-SOC AlertGENERAL DESCRIPTION
The CW2015 is an ultra-compact, host-side/packside, sensing resistor free, fuel gauging system IC for Lithium-ion(Li+) based batteries in handheld and portable devices. The CW2015 tracks Li+ battery’s operational condition and uses state-of-art algorithm to report the relative State-of-Charge (SOC) of very different battery chemistry systems (LiCoOx, polymer Li-ion, LiMnOx etc.).
