6.4 Device Functional Modes

The AMC0381D-Q1 operates in one of the following states:

  • OFF-state: The low-side supply (VDD2) is below the VDD2UV threshold. The device is not responsive. OUTP and OUTN are in Hi-Z state. Internally, OUTP and OUTN are clamped to VDD2 and GND2 by ESD protection diodes.
  • Missing high-side supply: The low-side of the device (VDD2) is supplied and within the Recommended Operating Conditions section. The high-side supply (VDD1) is below the VDD1UV threshold. The device outputs the VFAILSAFE voltage.
  • Analog input overrange (positive fullscale input): VDD1 and VDD2 are within recommended operating conditions but the analog input voltage VIN is above the maximum clipping voltage VClipping, MAX. The device outputs positive VCLIPout.
  • Analog input underrange (negative fullscale input): VDD1 and VDD2 are within recommended operating conditions but the analog input voltage VIN is below the minimum clipping voltage VClipping, MIN. The device outputs negative VCLIPout.
  • Normal operation: VDD1, VDD2, and VIN are within the recommended operating conditions. The device outputs a differential voltage that is proportional to the input voltage.

Table 6-1 lists the operating modes.
