The SparkFun Battery Babysitter is an all-in-one single-cell Lithium Polymer (LiPo) battery manager. Itís half battery charger, half battery monitor, and all youíll ever need to keep your battery-powered project running safely and extensively.

The Battery Babysitter features a pair of Texas Instruments LiPo-management ICs: a BQ24075 battery charger and a BQ27441-G1A fuel gauge. The charger supports adjustable charge rates of up to 1.5A, as well as USB-compliant 100mA and 500mA options. It also features power-path management, guaranteeing power to your project even if the battery has died. The self-calibrating, I2C-based BQ27441-G1A measures your batteryís voltage to estimate its charge percentage and remaining capacity. Itís also hooked up to a current-sensing resistor, which allows it to measure current and power! Itís a handy IC to have, if you ever need to keep an extra eye on your projectís power draw.

Features:

  • LiPo Charger and LiPo Fuel Gauge combined into one board
  • DIP-switch-selectable charge rates of 100mA, 500mA or 1.5A
  • MicroUSB port for charging, or external options
  • Dynamic power-path managment maintains a reliable output supply
  • On/Off switch disconnects the battery for more power saving
  • 5V-tolerant I2C interface to fuel gauge
  • Fuel gauge measures voltage, percentage, and current
