INA226 Voltage Current Power Monitor Alarm Function 36V Bidirectional I2C Module

Introduce The INA226 has a maximum 0ffset voltage of 10 microvolts uV a maximum gain error of 0 1 and is 10 times more accurate than industry leading competitors The device is a complete 16 bit single chip solution that provides fully programmable measurements of current voltage and power for a digital I2C interface The INA226 brings great advantages to designers of servers telecommunications equipment computers power management equipment and test equipment meeting their needs for accurate power measurements Main features and advantages Single chip solution with I2C interface supports current voltage and power measurements simplifying board design and addressing layout limitations without the need for external multiplexers or ADCs Industry s highest accuracy with 10 uV maximum 0ffset voltage and 0 1 maximum gain error enabling higher accuracy at lower currents and using smaller shunt resistors for lower I R losses Independently programmable conversion time and sample averaging technology not only simplifies the customization of each system s speed requirements but also reduces software and memory requirements 420 uA maximum quiescent current and 2 uA maximum shutdown current support efficient operation even with the integrated ADC and power multiplexer the INA226 consumes 3 5 less power than competing discrete solution 140 dB common mode rejection ratio CMRR and 36 V common mode voltage CMV ensure little or no change in 0ffset voltage over
