ROHM Semiconductor GmbH Precision Coulomb Counter / Low Side Current Monitor for High-current Applications BD7220FV-C

Description
BD7220FV-C is a coulomb counter IC for high-current applications. The product integrates a high-accuracy operational amp, a current accumulation logic circuit and a 16-bit ΔΣADC to perform current accumulation with high precision. The current sense input supports shunt resistors and output current sensors, and uses the SPI communication interface. BD7220FV-C only requires SPI commands to carry out the calibration necessary for high-precision measurement, so it can also get current accumulation information for battery state-of-charge estimation.
