Mode-controlled voltage excursion detector apparatus and a method of operating thereof

A mode-controlled voltage excursion detector apparatus for monitoring a supply voltage of a power supply applied to a load,

• the detector apparatus comprising:
• at least one voltage input operatively coupled to the power supply;
• an excursion event output for outputting voltage excursion event signals from the detector apparatus;
• a sensitivity control input for receiving from a mode entry module a signal indicative of potential voltage excursions, the signal comprising information about a current operation mode of the load;
• a voltage monitor operatively coupled to the at least one voltage input and the excursion event output, wherein the voltage monitor is configured to monitor the supply voltage, to detect an excursion event if the supply voltage exceeds or falls below at least one defined threshold, to generate from the voltage monitor an excursion event signal of the voltage excursion event signals upon detection of the excursion event and to provide the generated excursion event signal to the excursion event output of the detector apparatus for being outputted;
• and
• a sensitivity control module operatively coupled to the sensitivity control input and configured to receive the signal indicative of the potential voltage excursions from the sensitivity control input, wherein the sensitivity control module is further coupled to the voltage monitor and configured to disable the outputting of an excursion event signal generated during a defined period of time in response to the reception of the signal, which triggers the disabling of the outputting.
