Abstract: A voltage regulator circuit includes a first voltage regulator having a first output voltage selection pin set and producing a first output voltage based on a first digital signal received at the first output voltage selection pin set, and a second voltage regulator having a second output voltage selection pin set and producing a second output voltage based on a second digital signal received at the second output voltage selection pin set. The first and second voltage regulators are operable in a voltage tracking mode with the output voltage of the second voltage regulator tracking the output voltage of the first voltage regulator when digital signals received at the selection pin sets have a same value. An overvoltage sensor detects overvoltage events at the first voltage regulator. Control circuitry selectively avoids operation in voltage tracking mode as a result of an overvoltage event detected at the first voltage regulator.

Abstract: A method of compensating electromagnetic emissions of a device for use in a communication bus, the method including: transmitting a test signal over the communication bus; receiving, at the device, the test signal after propagation over the communication bus; performing frequency analysis processing of the test signal received to detect a set of harmonic components of the test signal received having an amplitude exceeding a certain threshold; storing respective values of frequency of harmonic components in the set of harmonic components having an amplitude exceeding the certain threshold; and generating and transmitting over the communication bus a set of compensation signals, each compensation signal in the set of compensation signals being a sinusoidal signal having a respective frequency equal to one of the frequencies stored, and being in anti-phase with respect to the harmonic component of the test signal received having the respective frequency.

Abstract: An embodiment circuit includes a plurality of heat-generating circuits, a heat-sensitive circuit exposed to heat generated during operation of the plurality of heat-generating circuit, and a temperature sensor disposed at a location between the heat-sensitive circuit and the plurality of heat-generating circuits, the temperature sensor being configured to generate an over-temperature signal as a function of temperature sensed at the location. The plurality of heat-generating circuits may be selectively deactivatable in an ordered sequence based on deactivation weights respectively assigned to the plurality of heat-generating circuits and in response to the over-temperature signal.

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.
