  • Circuit configuration and method for monitoring a micro-controller
    Patent number: 7178070
    Abstract: The invention relates to a method for monitoring a microcontroller having at least one normal operating state and one state with a reduced power consumption and to a circuit configuration for carrying out the method. The method enables the functionality of the microcontroller to be monitored even in the state with the reduced power consumption. The method includes steps of: during the normal operating state, receiving a status signal having pulses from the microcontroller and resetting the microcontroller if the pulses are not received within a predefined time pattern; and during the state with the reduced power consumption, transmitting a wakeup signal having a sequence of pulses to the microcontroller, and resetting the microcontroller if there is no confirmation by the microcontroller within a predefined time interval after a pulse of the wakeup signal.

  • Output level responsive switching on/off of a linear regulator
    Patent number: 7053592
    Abstract: A circuit configuration provides an output voltage from an input voltage. The circuit configuration has a voltage regulator with an input terminal for receiving an input voltage, an output terminal for providing an output voltage, and drive input for receiving a drive signal. A drive circuit is coupled to the drive input and switches the voltage regulator on and off in a clocked manner according to a state signal.
