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 0V to 26V. The device is powered from a single 2.7V to 5.5V
supply, and draws 350µA (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 programmable
addresses.
