LC709201F Datasheet Battery Monitor

Manufacturer: onsemi

Overview: Ordering number : ENA2031 LC709201F CMOS IC Battery Monitor IC http://onsemi.com Overview The LC709201F is an IC that measures the remaining power level of 1-cell lithium-ion secondary batteries by monitoring the battery voltage without an external sense resistor, and detects the remaining battery power level by current prediction. It monitors the battery voltage and realizes a function that precisely measures the remaining battery charge. In addition, the IC realizes the function for calculating the remaining battery power level even more accurately by utilizing a temperature correction function that makes use of the temperature input from a thermistor.

Key Features

  • Accuracy of remaining battery power level measurement.
  • Accuracy of ±5% during discharging from 100% to 0% (at an ambient operating temperature of 0°C to 50°C).
  • Measurement of remaining battery power level.
  • The remaining power level is measured four times a second and calculated with each measurement undertaken.
  • Interface.
  • I2Cbus, communication in slave mode up to 100kHz supported.
  • Ports.
  • I2C-bus communication pin.
  • Battery temperat.
