INA3221AIRGVT

The INA3221AIRGVT is a 3-channel high-side Current and Bus Voltage Monitor with an I²C- and SMBUS-compatible interface. The INA3221 monitor both shunt voltage drops and bus supply voltages, in addition to having programmable conversion times and averaging modes for these signals. The INA3221 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel. The INA3221 senses current on buses that can vary from 0 to 26V. The device is powered from a single 2.7 to 5.5V supply and draws 350µA (typical) of supply current.
