onsemi LC709209F Battery Fuel Gauges

onsemi LC709209F Battery Fuel Gauges are used for 1-Cell (1series N parallel) Lithium-Ion/Polymer batteries. The onsemi LC709209F is part of the Smart LiB Gauge family of fuel gauges which measure the battery’s Relative State Of Charge (RSOC). The devices use a unique algorithm called HG-CVR2. The HG−CVR2 algorithm provides accurate RSOC information even under unstable conditions (e.g., changes in battery, temperature, loading, aging, and self−discharge).

Features

  • High accuracy gauging
  • Low power consumption
  • Stable gauging
  • Small footprint
  • Alarm function, RSOC/Voltage/Temperature
  • I2C interface (up to 400kHz supported)
  • Battery lifetime measurement
  • Start gauging immediately stand-alone

Applications

  • Battery packs
  • Wearables/IoT devices
  • Smartphones/PDA devices
  • Digital cameras
  • Portable game players
  • USB-related devices
