Abstract:
An electronic fuse circuit for safeguarding a multi-channel electronic power distributor includes a driver circuit for each channel of the power distributor configured to control an electronic switch of a corresponding channel to assume a certain state, and a microcontroller interface configured to receive from a microcontroller a command for setting the state of the electronic switch of a corresponding channel. The driver circuit of the corresponding channel is configured to set the state of the electronic switch of the corresponding channel according to the command from the microcontroller. The electronic fuse circuit further includes a safety circuit for detecting a malfunction in the microcontroller and/or the power distributor. In the event of a detected malfunction in the microcontroller and/or the power distributor, the driver circuit of each channel is configured to set the state of the electronic switch of the corresponding channel according to a channel-specific preconfigured safety state.
