Patent number: 11716079Abstract: A method of operating a driver circuit includes receiving a data signal at a first input of an amplification circuit; amplifying, using the amplification circuit, the data signal to produce an output signal through an output pin; attenuating, using a feedback network, the output signal to produce a feedback signal; coupling the feedback signal to a second input of the amplification circuit; detecting, using a control circuit, a fault condition; and decoupling, responsive to detecting the fault condition, the feedback signal from the second input of the amplification circuit. In some embodiments, the driver circuit transmits a fault condition signal to an electronic control unit of an automobile.Type: GrantFiled: December 30, 2021Date of Patent: August 1, 2023Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Michal Olsak, Pavel Baros

Patent number: 11536588Abstract: An integrated circuit is provided for use in a sensor system having a plurality of sensing coils arranged in a star configuration coupled to terminals of an integrated circuit, such that a first and a second terminal are connected external to the integrated circuit via a loop including a first and a second sensing coil in the plurality of sensing coils. The integrated circuit includes: sensing circuitry for evaluation of sense signals received from the sensing coils via said terminals; a current source and a current sink coupled to respectively a first and a second of said terminals, such that upon supply of current from the current source a current is established through the loop external to the integrated circuit and a detection signal is generated; and an evaluator for evaluating one of more detection signals to detect failure and/or weakness within said loop.Type: GrantFiled: September 29, 2020Date of Patent: December 27, 2022Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Pavel Baros, Michal Olsak

Publication number: 20130135032Abstract: In an embodiment a circuit provides an active resistance that is adjusted with temperature, the active resistance has a magnitude and temperature coefficient that is selected by the values of external resistors. The active resistance is controlled by an active resistance controller that uses a temperature dependent source and a temperature stable source to control adjustment of a first adjustable resistance to maintain correspondence between a temperature dependent parameter and a temperature stable parameter, and adjusts a second adjustable resistance that is part of the active resistance in correspondence with adjustment of the first adjustable resistance.Type: ApplicationFiled: November 28, 2011Publication date: May 30, 2013Inventors: Pavel Horsky, Michal Olsak
