Power Supply Controller Digital Power Monitor 10-VSSOP The INA228 is an ultra-precise digital power monitor with a 20-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure a full-scale differential input of ±163.84 mV or ±40.96 mV across a resistive shunt sense element with common-mode voltage support from –0.3 V to +85 V. The INA228 reports current, bus voltage, temperature, power, energy and charge accumulation while employing a precision ±0.5% integrated oscillator, all while performing the needed calculations in the background. The integrated temperature sensor is ±1°C accurate for die temperature measurement and is useful in monitoring the system ambient temperature.
