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: An integrated device for driving a lighting load, such as a LED, has a first memory element, configured to store a nominal duty-cycle at a nominal supply voltage. An actual voltage acquisition element is configured to detect an actual supply voltage. A processing unit is coupled to the first memory element and to the actual voltage acquisition element and configured to calculate a voltage compensated duty-cycle. A driver unit is coupled to the processing unit and is configured to be supplied according to the voltage compensated duty-cycle.

Abstract: A driver circuit includes a supply node, a control node configured to receive a control signal, and an output node. An output transistor is coupled to the output node to provide the CAN bus drive signal via the current path through the output transistor. A current mirror is in a current line from the supply node to the output node through the output transistor. The current line includes an intermediate portion between the current mirror and the output transistor. The current mirror is configured to be switched, as a function of the control signal between a first, dominant mode, with the CAN bus drive signal applied to the output node via the output transistor, and a second, recessive mode, with the output transistor providing a high output impedance at the output node.

Abstract: A circuit includes a switching circuit including a first switch and a second switch. A current sensing circuit is coupled to the switching circuit to sense a first current through the first switch and to generate a first sensed current signal based on the sensed first current, and configured to sense a second current through the second switch and to generate a second sensed current signal based on the sensed second current. An output circuit is coupled to the current sensing circuit and is configured to generate a failure signal based on the first sensed current signal and the second sensed current signal.
