INA226 is a current divider and power monitor with I2C or SMBUS compatible interfaces. This device monitors the voltage drop of the shunt and the bus power supply voltage. Programmable calibration values, conversion times, and averages, combined with internal multipliers, can directly read ampere current and watt power. INA226 senses the current on the common mode bus voltage of the power supply voltage, which can vary from 0V to 36V. The working voltage of this device is 2.7V to 5.5V, and the typical power supply current is 330A. The device is specified to operate within a temperature range of -40 to 125 and has up to 16 programmable addresses on an I2C compatible interface. CJMCU-226- Supports 36V alarm function, bidirectional, high-precision, low-voltage and high-voltage power monitoring, I2C output current The maximum interference voltage of INA226 is 10 microvolts (uV), the maximum gain error is 0.1%, and the accuracy is 10 times that of industry-leading competitive products. This device is a complete 16 bit single-chip solution that provides comprehensive programmable measurements of current, voltage, and power for I2C interfaces. INA226 provides great advantages for designers of servers, computers, telecommunications equipment, power management equipment, and testing equipment, fully meeting the requirements of precise power measurement.
