INA226
Current shunt and power monitor measures shunt voltage and bus supply voltage through an I2C- or SMBus-compatible interface. The device senses bus voltages from 0 V to 36 V and operates from a 2.7 V to 5.5 V supply. It provides 16-bit resolution with programmable calibration, conversion time, averaging, and alert-limit functions. The monitor supports high-side or low-side sensing, 16 programmable addresses, and operation from -40 °C to 125 °C in a 10-pin VSSOP package.
