General Description

The CW2017 is an ultra-compact, system-side or pack-side, sensing resistor free, fuel gauging IC for Lithium-ion(Li+) based batteries in handheld and portable devices.

The CW2017 tracks the Li+ battery’s operation conditions and performs state-of-the-art algorithm to calculate the relative State-of-Charge (SOC) of very different battery chemistry systems (LiCoOx, polymer Li-ion, LiMnOx etc.).

The CW2017 includes a 14-bit Sigma-Delta ADC, a precision voltage reference and build-in NTC bias circuits.
