    Abstract: Systems and techniques are described for monitoring the operating temperature of one or more circuit elements, such as a metal oxide field effect transistor (MOSFET) switch, where the circuit element is used to control at least one phase of an electric motor. The systems and techniques may calculate temperature by determining at least two electrical signals from the circuit element taken at least two different times. This results in an accurate temperature calculation without requiring precise knowledge of the particular characteristics of each respective circuit element.

    Abstract: A device is operated in a low power mode of operation. The device receives a differential signal that includes a first polarity signal and a second polarity signal. A slope of a first direction is detected in the differential signal and a slope of a second direction is detected in the differential signal. A wakeup of the device is caused in response to the detection of the first slope of the differential signal and the second slope of the differential signal.

    Abstract: In general, the disclosure describes circuits and techniques to operate power switch driver circuits as well as techniques to dynamically change configuration parameters. The power switch driver circuit of this disclosure may be configured to received communication signals along the same signal paths as for pulse modulated switching control signals. In other words, the power switch driver circuit may receive a main function signaling, switching the power switches on and off, overlaid with a secondary function signaling, communication, which may include configuration parameters. In this manner the power switch driver circuit may receive both switching (commutation) function and communication function along the same signal path.

    Abstract: A device for excitation of a resolver comprising an excitation coil and one or more sensing coils includes circuitry. The circuitry is configured to amplify a carrier signal using a first gain value to generate an excitation signal for output to the excitation coil of the resolver and determine whether the excitation signal is outside of a threshold band of voltages. The circuitry is further configured to amplify the carrier signal using a second gain value, wherein the second gain value is generated based on whether the excitation signal is outside of the threshold band of voltages.

    Abstract: A method includes detecting in a communication bus a write command to a first circuit and comparing a write address of the write command with a set of safe addresses. When the write address matches a safe address of the set of safe addresses, an error correction code (ECC) is generated based at least on write data of the write command, and the ECC is stored in a memory of a parameter safe storage circuit. A read command to the first circuit is detected in the communication bus, a read address of the read command is compared with the set of safe addresses, and, when the read address matches a safe address of the set of safe addresses, it is determined whether read data of the read command is corrupted based on the stored ECC, and an error notification is provided when the read data is determined to be corrupted.
