The INA3221-Q1 is a three-channel, high-side current and bus voltage
monitor with an I2C- and SMBUS-compatible interface. The
INA3221-Q1 monitors both shunt voltage drops and bus supply voltages, in addition
to having programmable conversion times and averaging modes for these signals. The
INA3221-Q1 offers both critical and warning alerts to detect multiple
programmable out-of-range conditions for each channel.
The INA3221-Q1 senses current on buses that can vary from 0 V to 26 V.
The device is powered from a single 2.7-V to 5.5-V supply, and draws 350 µA (typ) of supply
current. The INA3221-Q1 is specified over the operating temperature range of
–40°C to +125°C. The I2C- and SMBUS-compatible interface features four
