ROHM Parametric

Coulomb Counter

Coulomb Counter

ROHM’s Coulomb Counter IC combines a high-accuracy current detection amp, A/D converter, and integrated logic on a single chip. Features include interrupt functions for overcurrent and battery capacity detection, a calibration function for ensuring high accuracy, and a voltage measurement function for the battery and thermistor, making it possible to measure the remaining battery capacity of not only li-ion batteries, but various types of secondary batteries as well.
