SparkFun Coulomb Counter Breakout - LTC4150

The SparkFun Coulomb Counter Breakout - LTC4150 is a unique device that functions as an odometer for electrical current. This innovative tool consistently monitors the current your sensor is using, accumulates it, and generates a pulse each time a specific amount of amp-hours have been used. With this device, you can always know exactly how much of your battery is left, assuming you start with a full one.

The Coulomb Counter Breakout is easy to install and use. It features headers labeled IN and OUT on one end. You simply connect your battery or power supply to the IN header or JST battery connector, and connect the OUT header to your project. On the other end of the Coulomb Counter, you’ll find a header with six pins. These pins, which include VIO (Voltage Input), INT (Interrupt), POL (Polarity), GND (Ground), CLR (Clear), and SHDN (Shutdown), need to be connected to your microcontroller. By installing this breakout between your power source and your circuit, all the current your circuit uses will pass through the Coulomb Counter to be measured.

The SparkFun Coulomb Counter Breakout - LTC4150 is not only functional but also efficient. It operates on a voltage of 2.7V - 8.5V and a current of 1A. It indicates both charge quantity and polarity and has a ±50mV sense voltage range. With a 32.55Hz/V charge count frequency and a 1.5μA shutdown current, this device offers a high level of performance.

For your convenience, SparkFun provides a variety of resources to assist you in using the Coulomb Counter Breakout. These include a schematic, Eagle Files, a hookup guide, a datasheet for the LTC4150, example code and design files on GitHub, and a product video.

The SparkFun Coulomb Counter Breakout - LTC4150 is an innovative tool that offers a unique solution for monitoring and measuring electrical current. Whether you're a professional or a hobbyist, this device is sure to be a valuable addition to your toolkit.
