LC709201F: Battery Fuel Gauge
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 ±5% during discharging from 100% to 0% (at an ambient operating temperature of 0°C to 50°C)
- The remaining power level is measured four times a second and calculated with each measurement undertaken.
- I2C bus, communication in slave mode up to 100kHz supported
