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.

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
