9.2 Typical Application

UCD90160A apps_circuit_slvsdd4.gifFigure 32. Typical Application Schematic

NOTE

Figure 32 is a simplified application schematic. Voltage dividers such as the ones placed on VMON1 input have been omitted for simplifying the schematic. All VMONx pins which are configured to measure a voltage that exceeds the 2.5V ADC reference are required to have a voltage divider.
