SparkFun BQ27441-G1A LiPo Fuel Gauge Arduino Library

SparkFun Battery Babysitter

SparkFun Battery Babysitter (featuring the BQ27441-G1A LiPo Fuel Gauge) (PRT-13777)

Texas Instrument's BQ27441-G1A is a self-calibrating, I2C-based fuel gauge for lithium polymer (LiPo) batteries -- it measures your battery�s voltage to estimate its charge percentage and remaining capacity. The chip is also hooked up to a current-sensing resistor, which allows it to measure current and power! The fuel gauge makes up half of the SparkFun Battery Babysitter.

This Arduino library abstracts away all of the low-level I2C communication, so you can easily initialize the fuel gauge then read voltage, state-of-charge, current, power, and capacity. It also implements all of the chip's low-battery, and SoC-change alerts on the GPOUT pin.
