RT9428 Overview
The RT9428 is a pact, host-side fuel gauge IC for lithium-ion (Li+) battery-powered systems. For the embedded Fuel Gauge function, the state-ofcharge (SOC) calculation is based on the battery voltage information and the dynamic difference between battery voltage and relaxed OCV, by using iteration to estimate the increasing or decreasing SOC. Voltage-based algorithm can support smoothly SOC and does not accumulate...
