INA226 Current Shunt and Power Monitors

Texas Instruments offers the INA226 36 V, bi-directional, ultra-high accuracy, low-/high-side, I²C out current/power monitors with alert

Image of Texas Instruments' INA226 Current Shunt and Power MonitorsTexas Instruments' 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. Programmable calibration value, conversion times, and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts.

The INA226 senses current on common-mode bus voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device operates from a single 2.7 V to 5.5 V supply, drawing a typical of 330 µA of supply current. The device is specified over the operating temperature range between -40°C and +125°C and features up to 16 programmable addresses on the I2C-compatible interface.
