  • Monitoring circuit and method for function monitoring
    Patent number: 11656276
    Abstract: A monitoring circuit and a method for function monitoring is disclosed where the device includes the input being connected with a first subassembly that detects a frequency range of the status signal, with the first subassembly being connected with a second subassembly to implement a logical signal combination. The second subassembly is connected with a third subassembly generating a delayed output signal. The method compares a frequency fsw of the status signal with a lower first cutoff frequency f1 and an upper second cutoff frequency f2. When the frequency fsw of the status signal is located within the predetermined frequency range, the functional reliability signal is provided with a first voltage level, and when the frequency fsw of the status signal is located outside of the predetermined frequency range, the functional reliability signal is provided with a second voltage level that is different from the first voltage level.
