RT9428 Datasheet (Richtek) - Host-Side Single Cell Lithium Battery Gauge

RT9428, Host-Side Single Cell Lithium Battery Gauge

The RT9428 is a compact, 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 iteratio
