SparkFun Battery Babysitter (PRT-13777)
The SparkFun Battery Babysitter is an all-in-one single-cell lithium polymer (LiPo) battery manager. It’s half battery-charger, half battery monitor, and it’s all you’ll ever need to keep your battery-powered project running safely and extensively.
The Battery Babysitter features a pair of Texas Instruments LiPo-management IC’s: a BQ24075 battery charger and a BQ27441-G1A fuel gauge. The BQ24075 supports adjustable charge rates up to 1.5A, as well as USB-compliant 100mA and 500mA options. It also features power-path management, guaranteeing reliable power to your project.
The self-calibrating, I2C-based BQ27441-G1A 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! It’s a handy IC to have, especially if you ever need to keep an extra eye on your project’s power draw.
