CW2017 is an ultra-compact, sensing resistor free, fuel gauging ICs for Lithium-ion based batteries. It tracks battery charging/discharging conditions and utilize patented “FastCali” gauging algorithm to report the relative State-of-Charge (SOC) of batteries, including LiCoOx, polymer Li-ion, LiMnOx etc.Features • System-Side or Pack-Side Fuel Gauging • ±3% Maximum Total SOC Measurement Error • 14-bit ADC for Cell Voltage and Temperature Measurement ...
