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
