CW2017 Datasheet (Cellwise) - Lithium-ion Fuel Gauge

CW2017, Lithium-ion Fuel Gauge

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-
