Abstract
The disclosure provides a device for operating an electronic system. The device includes a power supply unit that, during operation, provides a supply voltage on a supply potential output. The power supply unit has an enable input via which the supply voltage can be enabled and disabled by an enable signal. In a power-latch phase of the electronic system in which the enable signal is not present, the power supply unit provides the supply voltage upon receiving a trigger signal even when the enable signal is not present. The device includes a microcontroller supplied with the supply voltage on a second supply potential input connection when the enable signal is present or when the microcontroller, in the power-latch phase, generates the trigger signal and transmits it to the trigger signal input. Upon receiving a control command, the power supply unit suppresses deactivation of the supply voltage for supplying the microcontroller.
