Abstract: A system includes lighting devices coupled to output supply pins, a microcontroller circuit, and a driver circuit, which receives data therefrom, and switches coupled in series to the lighting devices. The driver circuit includes output supply pins and selectively propagates a supply voltage to the output supply pins to provide respective pulse-width modulated supply signals at the output supply pins. The driver circuit computes duty-cycle values of the pulse-width modulated supply signals as a function of the data received from the microcontroller circuit. The lighting devices include at least one subset coupled to the same output supply pin. The microcontroller individually controls the switches via respective control signals to individually adjust a brightness of the lighting devices in the at least one subset of lighting devices.

Abstract: A fail-safe device may be coupled to a main device for actuating a switch responsive to a failure. The fail-safe device may include a fail-safe circuit, and an isolation trench surrounding the fail-safe circuit and isolating the fail-safe circuit from the main device. The fail-safe device may include an internal power supply connection, an internal reference voltage connection, a self-biased drive block configured to drive the at least one switch, and a receiver configured to receive failure signals from the main device.

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: The power supply device comprises a supply transistor commanded by a command signal and providing electric power to a lighting module, and a driving means configured to selectively generate, depending on an instruction signal representative of the structure of said at least one lighting module, a first command signal able to command the supply transistor into an ohmic regime, a second command signal able to command the supply transistor into a pulse width modulation regime involving an alternation of ohmic regimes and blocked regimes, and a third command signal able to command the supply transistor into a saturated regime.

Abstract: A vehicle communication network includes electronic control units arranged in a plurality of groups. The electronic control units pertaining to the same group are coupled to each other via a respective dedicated communication bus. A central controller is coupled to the plurality of local controllers. Electrical loads are coupled to one of the electronic control units. Each of the electronic control units is configured to decode the received CAN frame to produce the actuation signal for a respective electrical load in response to a CAN frame being received from the respective local controller and transmit a CAN wake-up frame to the respective local controller and encode the feedback signal into a CAN frame for transmission to the respective local controller in response to the feedback signal being received from the respective electrical load.
