A3221 Triple-Channel Shunt Current & Voltage Sensor Board – Power Supply Monitor

The INA3221 is a triple-channel, high-side current and bus voltage monitor designed for accurate power-supply monitoring. It measures both shunt voltage drops and bus supply voltages across three independent channels, communicating via an I²C- and SMBUS-compatible interface.

With programmable conversion times and averaging modes, the INA3221 allows flexible measurement configuration. It also includes programmable critical and warning alerts to detect multiple out-of-range conditions on each channel, supporting reliable system monitoring and protection.

The device senses current on buses ranging from 0 V to 26 V and operates from a single 2.7 V to 5.5 V supply, drawing 350 µA (typical). It is specified for operation across a wide –40°C to +125°C temperature range and supports four programmable I²C addresses for system integration.


Key Features

  • Triple-channel high-side current and bus voltage monitoring

  • Senses bus voltages from 0 V to 26 V

  • Reports both shunt voltage and bus voltage

  • High accuracy performance

    • Offset voltage: ±80 µV (max)

    • Gain error: 0.25% (max)

  • Configurable averaging options

  • Programmable alert and warning outputs

  • Four programmable I²C addresses
