Electronic circuit and method for powering multiple electronic systems of an electronic control unit of a vehicle, and electronic control arrangement of a vehicle

A method for powering multiple electronic systems in an electronic control unit of a vehicle, the method comprising:

• switching on an input voltage to the electronic control unit;
• detecting the switched on input voltage and generating a first set signal depending on the detected input voltage by a power input detector;
• receiving the first set signal by each of multiple latches and generating a respective enable signal depending on the first set signal by each of the multiple latches and
• receiving the respective enable signal by a respective power management circuitry and providing power to a respective electronic system of the multiple electronic systems depending on the respective enable signal.

An electronic control arrangement for a vehicle, the electronic control arrangement comprises an electronic circuit any comprising:

• a power input detector, which is configured to detect an input voltage and to generate a first set signal at an output of the power input detector depending on the detected input voltage;
• multiple latches,
• wherein each of the multiple latches is associated with one of the multiple electronic systems,
• wherein the output of the power input detector is connected to a respective set input of each of the multiple latches.
• wherein each of the multiple latches is configured to generate a respective enable signal at an output of the respective latch depending on the first set signal;
• multiple power management circuitries, wherein each of the multiple latches is associated to one of the multiple power management circuitries, wherein each respective output of each of the multiple latches is connected to its associated power management circuitry, wherein each of the multiple power management circuitries is associated to one of the multiple electronic systems and configured to power its associated electronic system depending on the enable signal;
• and
• an electronic control unit, wherein the electronic control unit comprises the multiple electronic systems;
• or
• the electronic control arrangement comprises an electronic control unit, which comprises the electronic circuit, wherein the electronic circuit comprises the multiple electronic systems.
