LTC4150 Coulomb Counter Battery Check Sensor Module

600.00 500.00

Odometers are useful where battery uses. The LTC4150 Coulomb Counter Breakout is here to act as odometer for current. This breakout is capable of constantly monitoring the current your sensor is using, is able to add it up, and will give you a pulse each time a given amount of amp-hours have been used. When used effectively with a full battery, it will always know exactly how much of it is left.

At one end of the Coulomb Counter Breakout are headers labeled IN and OUT. If battery or power supply is connected to the IN header or JST battery connector and the OUT header should be connected with the project. At the other end of the Coulomb Counter there are six header pins. These are the pins need to connect to microcontroller and it should be included VIO (Voltage Input), INT (Interrupt), POL (Polarity), GND (Ground), CLR (Clear), and SHDN (Shutdown). Simply install this breakout out between your power source with the circuit, then the current in the circuit will pass through the Coulomb Counter which would be measured.
