Texas Instruments INA3221AIRGVT

Description
The INA3221 is a triple-channel, high-side current and bus voltage monitor with an I²C interface. It monitors both shunt voltage drops and bus supply voltages, with programmable conversion times and averaging modes for these signals. The INA3221 offers 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 V to 26 V. It is powered from a single 2.7-V to 5.5-V supply and draws 350 μA (typ) of supply current. The INA3221 is specified over the operating temperature range of -40°C to 125°C.
The I²C interface features four programmable addresses.
