Publication number: 20230267087Abstract: 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.Type: ApplicationFiled: April 28, 2023Publication date: August 24, 2023Inventors: Fred Rennig, Ludek Beran

Patent number: 11483909Abstract: A control circuit for a voltage source generates a reference signal for a voltage source, wherein the reference signal indicates a requested output voltage to be generated by the voltage source. A digital feed-forward control circuit computes a digital feed-forward regulation value indicative of a requested output voltage by determining a maximum voltage drop at strings of solid-state light sources. A digital feed-back control circuit determines a minimum voltage drop for current regulators/limiters for the strings and determines a digital feed-back correction value as a function of the minimum voltage drop. The control circuit then sets the reference signal after a start-up as a function of the digital feed-forward regulation value and corrects the reference signal as a function of the digital feed-back correction value.Type: GrantFiled: November 10, 2021Date of Patent: October 25, 2022Assignees: STMicroelectronics S.r.l., STMicroelectronics Application GmbH, STMicroelectronics Design and Application S.R.O.Inventors: Donato Tagliavia, Vincenzo Polisi, Calogero Andrea Trecarichi, Francesco Nino Mammoliti, Jochen Barthel, Ludek Beran
