Patent number: 11973457Abstract: An embodiment driver circuit comprises a power supply pin configured to receive a power supply voltage, and a set of control pins configured to provide a set of control signals for controlling switching of a set of switches of an h-bridge circuit comprising a pair of high-side switches and a pair of low-side switches. The driver circuit comprises control circuitry coupled to the control pins and configured to generate the control signals, and sensing circuitry coupled to the power supply pin and configured to generate a detection signal indicative of the power supply voltage exceeding a threshold value. The control circuitry is sensitive to the detection signal and is configured to generate the control signals to activate one of the pair of high-side switches and the pair of low-side switches and de-activate the other of the pair of high-side switches and the pair of low-side switches.Type: GrantFiled: May 18, 2021Date of Patent: April 30, 2024Assignees: STMicroelectronics (Alps) SAS, STMicroelectronics S.r.l., STMicroelectronics Application GMBHInventors: Aldo Occhipinti, Christophe Roussel, Fritz Burkhardt, Ignazio Testoni

Patent number: 11889594Abstract: 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.Type: GrantFiled: March 11, 2022Date of Patent: January 30, 2024Assignees: STMicroelectronics (Grenoble 2) SAS, STMicroelectronics S.r.l., STMicroelectronics Application GMBHInventors: Manuel Gaertner, Philippe Sirito-Olivier, Giovanni Luca Torrisi, Thomas Urbitsch, Christophe Roussel, Fritz Burkhardt
