Battery Monitor IC
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
• Battery temperature reading control pin
• Analog voltage input pin for battery temperature
• Reset pin
