RT9427R 5A System Side Single Cell Fuel Gauge with Build-In Sense Resistor General Description The RT9427R Li-Ion/Li-Polymer battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell battery packs. The RT9427R resides within the system's main board and manages a non-removable battery or removable battery pack. The RT9427R reports StateOfCharge, StateOfHealth, FullChargeCapacity, TimeToEmpty and CycleCount based on the Voltaic Gauge with Current Sensing (VGCS) algorithm by using the voltage difference between battery voltage and OCV to calculate the increasing or decreasing SOC, with current sensing compensation to report battery SOC.
