16-bit current monitor48 V common-modeI2C/SMBusSOT-23-thinHigh-side sensingLow-side sensing

INA232BIDDFR is a 16-bit I2C/SMBus current-shunt monitor for measuring current, bus voltage and calculated power on rails with up to 48 V common-mode voltage.

Best for

  • High-side or low-side current sensing
  • 48 V power-rail monitoring
  • Systems needing digital current, voltage and power telemetry

Avoid if

  • The shunt drop can exceed the selected ±81.92 mV or ±20.48 mV full-scale range
  • An analog-only current-sense output is required

Check before use

  • Program the calibration register after each power cycle
  • Use Kelvin connections to the shunt resistor
  • Review ALERT threshold scaling for the selected function
