  • Publication number: 20210110239
    Abstract: An exemplary embodiment of a circuit for determining information about the position, attitude, or orientation of a magnet comprises an input interface configured to receive components of a magnetic field produced by the magnet. An evaluation logic unit corresponds to at least one trained neural network and is configured to determine the information about the position, attitude, or orientation of the magnet on the basis of the received components.

  • Publication number: 20210055130
    Abstract: A magnetic angle sensor includes a semiconductor chip that includes: a pair of vertical Hall sensor elements configured to generate vertical Hall sensor signals in response to a magnetic field impinging thereon; a first pair of lateral Hall sensor elements configured to generate first lateral Hall sensor signals in response to the magnetic field impinging thereon; a second pair of lateral Hall sensor elements configured to generate second lateral Hall sensor signals in response to the magnetic field impinging thereon; and a sensor circuit configured to: determine a first angle value corresponding to an orientation of the magnetic field based on the vertical Hall sensor signals, determine a second angle value corresponding to the orientation of the magnetic field based on the first and the second lateral Hall sensor signals, and determine whether the first and the second angle values are within an acceptable tolerance range of each other.

  • Publication number: 20210056064
    Abstract: The described techniques address deadlocking issues associated with interconnected hardware devices that share bus lines associated with a digital communication interface. A watchdog-based solution is described that may be implemented internally within the interconnected hardware devices or, alternatively, as an external component. The watchdog circuity may monitor a logic state of one or more internal connections of a hardware device and cause one or more portions of the hardware device to reset when a deadlock condition is detected using this internal monitoring.

  • Patent number: 10802053
    Abstract: This disclosure is directed to techniques that may accurately determine the amount of current flowing through a power switch circuit by measuring the voltage across the inherent impedance of the circuit connections. One connection may include a low impedance connection between the power switch output and ground, where the low impedance connection may be on the order of milliohms. By using a four-wire measurement, the sensing connections are not in the current path, so the measured value may not be affected by the current. The connection that makes up the current path can be accomplished with a variety of conductive materials. Conductive materials may have a temperature coefficient of resistivity that may impact a measurement of electric current as the temperature changes. Measuring the temperature of the current path, along with the voltage across the connection, may allow a more accurate current measurement.

  • Patent number: 10606794
    Abstract: A slave device may receive a clock signal from a master device via a bus. The slave device may detect a first pulse of the clock signal. The first pulse indicates that a bit is to be written to a slave shift register of the slave device. The slave device may identify a timeout threshold associated with the clock signal. The slave device may determine that the timeout threshold expired without a second pulse from the clock signal being detected. The slave device may reset, based on the timeout threshold expiring, the slave shift register to synchronize the slave shift register with a master shift register of the master device.

  • Publication number: 20200096363
    Abstract: A device may determine a sensor identifier corresponding to a sensor integrated circuit (IC) associated with a sensor system. The device may provide the sensor identifier corresponding to the sensor IC. The device may receive, based on providing the sensor identifier, compensation parameter information associated with the sensor IC. The device may cause a set of compensation parameters, associated with the compensation parameter information, to be stored on a controller associated with the sensor system. The set of compensation parameters may include one or more parameters associated with correcting a measurement performed by the sensor IC or a safety result provided by the sensor IC.

  • Publication number: 20190310325
    Abstract: Transistor devices are provided. In some example implementations, a magnetic field sensor chip is fitted on a load electrode of a transistor chip. In other example implementations, two magnetic field sensors are arranged on a load electrode of a transistor chip in such a way that they measure different effective magnetic fields in the event of current flow through the transistor chip.
