LC709204F is a Fuel Gauge for 1-Cell Lithium-Ion/Polymer Batteries

It uses a unique algorithm called HG-CVR2 to accurately measure a battery's RSOC (Relative State of Charge) even under unstable conditions such as changes in battery temperature, loading, aging and self-discharge. The algorithm can be easily configured to begin taking battery measurements by setting up a few parameters after battery insertion, reducing complexity in the development process. LC709204F also includes SOH reporting and multiple integrated alarm functions to support battery safety.

Features
  • High accuracy gauging
  • Low power consumption
  • Stable gauging
  • Small footprint
  • Alarm function: RSOC / Voltage / Temperature
  • Battery lifetime measurement
  • Multi-thermistor support
  • I2C interface(up to 400kHz supported)
Benefits
  • Accurate RSOC even in low temperature ranges
  • Longer battery life
  • Stable gauging under different battery conditions such as battery aging
  • 40% size reduction through elimination of current sensing resistor
  • Provides system safety
  • Integrated safety monitoring of SOH(State of Health), Time to Full, Time to Empty
  • Monitoring of system and battery temperature
  • Easy configuration over the I2C control bus
