Abstract: A thermal control process for an electronic power device including a multi-junction integrated circuit may include defining a first and at least one second groups of junctions, with each group including one first and at least one second junctions, and associating a thermal detector with each group. A first group control may be executed which detects group electric signals representative of the temperature detected by the thermal detectors, processes the group electric signals with reference to a group critical thermal event, identifies a critical group when the corresponding group electric signal detects the critical group thermal event, and generates group deactivating signals suitable for selectively deactivating the first and the at least one second junctions of the identified critical group with respect to the remaining junctions of the integrated circuit.

Abstract: A device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

Abstract: An electronic device includes a CAN protocol controller, a first communication port configured to be coupled to a first segment of a differential bus, and a second communication port configured to be coupled to a second segment of the differential bus. A first CAN transceiver circuit is coupled to the CAN protocol controller and is configured to receive a first CAN transmission signal and to transmit a first CAN reception signal. The first CAN transceiver is configured to drive a differential voltage at the first segment of the differential bus based on the first CAN transmission signal and to sense a differential voltage at the first segment of the differential bus. The second communication port is enabled in response to a control signal being de-asserted and disabled in response to the control signal being asserted.
