Ordering number : ENA2031 LC709201F CMOS IC 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.

LC709201F 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 calc
