RT9426A - System Side Single Cell Fuel Gauge

General Description

The RT9426A Li-Ion / Li-Polymer battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell battery packs.

The RT9426A resides within the battery pack or on the system's main board and manages a non-removable battery or removable battery pack.

Key Features

  • Support System Side Fuel Gauging.
  • Battery Fuel Gauge for 1-Series (1sXp) Li-Ion/Li-Polymer.

RT9426A System Side Single Cell Fuel Gauge General Description The RT9426A Li-Ion / Li-Polymer battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell battery packs. The RT9426A resides within the battery pack or on the system's main board and manages a non-removable battery or removable battery pack. The RT9426A 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. Voltaic Gauge with Current Sensing algorithm can support smoothly SOC and does not accumulate error with time and current.
