Figure 53 Simplified Application Diagram with the Alternate Measurement Function via WK1 and WK2
Note: This is a very simplified example of an application circuit. The function must be verified in the real
application.WK1 must be connected to signal to be measured and WK2 is the output to the microcontroller
supervision function. The maximum current into WK1 must be <500uA. The minimum current into WK1
should be >5uA to ensure proper operation.
