Patent number: 11971279Abstract: A magnetic field sensor includes a sensor and a processing circuit. The sensor is designed to generate on the basis of a varying magnetic field an oscillation signal that fluctuates around a mean value. The processing circuit is designed to generate an output signal on the basis of the oscillation signal. The processing circuit is designed, in a high-resolution mode different than a low-resolution mode, in each case to generate a mean value crossing pulse in the output signal when the oscillation signal attains the mean value, and to generate in each case a limit value crossing pulse in the output signal when the oscillation signal attains at least one limit value different than the mean value. A pulse width of at least either the mean value crossing pulse or the limit value crossing pulse is set to indicate that the magnetic field sensor is operating in the high-resolution mode.Type: GrantFiled: October 13, 2022Date of Patent: April 30, 2024Assignee: Infineon Technologies AGInventors: Patricia Lorber, Simone Fontanesi, Tobias Werth

Patent number: 11578993Abstract: An apparatus, for determining a relative direction of a movement of an encoder object depending on a magnetic field which is generated or influenced by the encoder object. A magnetic field sensor generates two sensor signals based on the magnetic field, that indicate a profile of the magnetic field in the event of a relative movement between the encoder object and the magnetic field sensor, that fluctuate around a mean value and are phase-shifted 90° to one another. The processing circuit calculates an angle based on the two sensor signals, and determines the relative direction of the movement of the encoder object based on a gradient of the angle between a switch-on time of the apparatus and a threshold value angle which is reached thereafter or based on a gradient of the angle between the situation of two successive threshold value angles being reached.Type: GrantFiled: October 7, 2019Date of Patent: February 14, 2023Assignee: Infineon Technologies AGInventors: Simone Fontanesi, Tobias Werth

Patent number: 11391602Abstract: A periodic sensor signal representing a varying rotation angle detected by a rotation angle sensor is compared to a number of thresholds to detect threshold crossings of the periodic sensor signal. An output signal including a pulse pattern at the time of a threshold crossing may be generated only if the direction of rotation has not changed since an immediately preceding threshold crossing. A number of consecutive threshold crossings which take place without a change in the direction of rotation may be counted and an update of the offset register is performed only if the number of consecutive threshold crossings which take place without a change in the direction of rotation is equal to or higher less than the number of thresholds.Type: GrantFiled: September 24, 2020Date of Patent: July 19, 2022Inventors: Alessandro Petri, Simone Fontanesi, Filippo Grillotti, Andrea Possemato, Massimiliano Zilli
