LTC4150 coulomb counter module tracks the amount of charge flowing in and out of your battery, helping you calculate remaining battery capacity more precisely than simple voltage detection. It supports high-side sampling and outputs interrupt pulses plus polarity signal to tell charge or discharge status. No precision crystal oscillator required for operation. It is widely used for lithium battery fuel gauge, portable power bank testing, DIY battery monitoring system, RC power supply inspection and embedded power evaluation projects. Please match proper sampling resistor according to your expected current range.
