Product Description

The INA3221 is a three-channel, high-side current and bus voltage monitor with an I2C and SMBUS compatible interface. The INA3221 not only monitors the shunt voltage drop and bus supply voltage, but also provides a programmable conversion time and average calculation mode for these signals. The INA3221 provides critical alarms and warning alarms to detect a variety of programmable out-of-range conditions on each channel.
The current on the INA3221 sensing bus (voltage varies from 0V to +26V). This device is powered by a single supply from 2.7V to 5.5V, with a supply current consumption of 350μA (typical). The INA3221 has a rated operating temperature range of -40°C to +125°C. The I2C and SMBUS compatible interface has four programmable addresses.
