INA226 Module
Description
The INA226 is a current shunt and power monitor with an I2C™- or SMBUS-compatible interface. Thedevice monitors both a shunt voltage drop and bussupply voltage. Programmable calibration value,conversion times, and averaging, combined with aninternal multiplier, enable direct readouts of current inamperes 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 330μA of supply current. The device is specified over the operating temperature range between –40°C and125°C and features up to 16 programmable addresses on the I2C-compatible interface

INA231 Module


The INA231 is a current shunt and power monitor with a 1.8V I2C-compatible interface (featuring 16 programmable addresses). This device monitors the shunt voltage drop and bus supply voltage, providing enhanced protection by asserting the ALERT pin when corresponding values exceed programmed limits.


Programmable calibration values, conversion times, and averaging combined with an internal multiplier enable direct readings of current values in Amperes and power values in Watts, thus reducing the host processing load.


INA231 measures current on a bus voltage ranging from 0V to 28V and is powered by a single supply ranging from 2.7V to 5.5V, consuming 330μA (typical) of supply current. The operating temperature range for the INA231 is rated from -40°C to +125°C. There are two versions of the INA231: the INA231A starts up performing continuous conversions of shunt and bus voltage, whereas the INA231B starts up in a low-current shutdown mode; this module uses the INA231A version.
