Automotive power systems such as traction inverters are divided into two or more voltage domains that are galvanically isolated from each other. For example, the high-voltage domain includes the HV battery and the power stage of the traction inverter. The low-voltage domain includes the system controller and human interface. The controller measures the value of the DC bus voltage while remaining galvanically isolated from the high-voltage domain for safety reasons. With the high-impedance input and galvanically isolated output, the AMC0381D-Q1 enables this measurement.
