INA3221 Triple Channel I2C Output Current, Shunt and Bus Voltage Monitor

The INA3221 Triple Channel I2C Output Current is a three-channel, high-side current and bus voltage monitor with an I2C interface. The INA3221 monitors 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 V to +26 V. The device is powered from a single 2.7V to 5.5V 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.
