INA3221 Current meter module I2C

Description

INA3221 Current Meter Module I2C, is a three channel high-side current and bus voltage monitor with an I2C and SMBUS compatible interface. The INA3221 monitors both shunt voltage drops and bus supply voltages, along with programmable conversion time and averaging modes for these signals. The INA3221 provides both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel. The INA3221 detects current on buses ranging from 0 V to 26 V. The device is powered by a single 2,7 V to 5,5 V supply and draws 350 uA (typ) of supply current. The INA3221 is rated for an operating temperature range of -40°C to +125°C. The I2C and SMBUS compatible interface has four programmable addresses.
