INA226 - Bi-Directional Current and Power Monitor

General Description

The INA226 is a current shunt and power monitor with an I2C™- or SMBUS-compatible interface.

The device monitors both a shunt voltage drop and bus supply voltage.

Key Features

  • Senses bus voltages from 0V to 36V.
  • High-side or low-side sensing.
  • Reports current, voltage, and power.
  • High accuracy:.
  • Gain error: 0.1% (maximum).
  • Offset: 10μV (maximum).
  • Configurable averaging options.
  • 16 programmable addresses.
  • Operates from 2.7V to 5.5V power supply.
  • 10-pin DGS (VSSOP) package 2.
