The SGM90800 is an analog front end (AFE) designed for precise digital power monitor with an I2C or SMBus-compatible digital interface. The device provides bus supply voltage, shunt voltage and internal temperature monitor. The internal high resolution ADC, with flexible configurations including calibration value, conversion times as well as average numbers support direct fetch of current values in amperes and power values in watts.
The SGM90800 can measure a differential input voltage of ±163.84mV with common-mode voltage from 0V to 120V while the shunt voltage measurement pins IN+ and IN- can survive under a wide common voltage from -10V to 120V. The bus voltage measurement supports the range from 0V to 120V or 0V to 85V. The integrated temperature sensor has ±1℃ (TYP) accuracy for die temperature measurement, which is useful in the system level temperature calibrations.
With low offset and drift design of the SGM90800, it is suitable for applications under wide range of temperature variation and simplifies the calibration. These features also make the device suitable for precise sensing systems. Two shunt voltage input ranges help expand the current measurement range.
The SGM90800 is available in a Green MSOP-10 package.
