Power Management (PMIC)

Current MonitorVoltage MonitorI2CSMBusPower Management

The INA3221 is a versatile 3-channel high-side current and bus voltage monitor with I2C/SMBus interface, ideal for multi-rail power management.

Best for

  • Multi-rail power monitoring
  • System health diagnostics
  • Current sensing in telecom/server hardware

Avoid if

  • Applications requiring >26V bus monitoring
  • Extremely space-constrained designs where a single-channel monitor suffices

Check before use

  • Ensure shunt resistors are placed close to the device pins for accuracy.
  • Verify pull-up resistor values for I2C lines.
