摘要： A circuit for controlling a motor that includes control circuitry configured to determine whether a commutation event has occurred for a first sector of a plurality of sectors of a cycle for the motor based on a first selected phase current signal and a second selected phase current signal. In response to a determination that the commutation event has occurred for the first sector, the control circuitry is configured to determine that the motor is operating in a second sector of the plurality of sectors of the cycle for the motor. The control circuitry is further configured to determine a second angle of stator voltage vector for the motor based on the determination that the motor is operating in the second sector and generate the control signal based on the second angle of stator voltage vector for the motor.

摘要： A driver may comprise a first node, a second node, and processing circuitry. The first node is configured to receive a command from controller circuitry. The second node is configured to receive a commutation signal for activating or deactivating a switch. The processing circuitry is configured to determine, based on the received command, an activation setting for an activation characteristic for the switch and a deactivation setting for a deactivation characteristic for the switch and drive the switch based on the commutation signal. To drive the switch, the processing circuitry is configured to change, at a first time, the deactivation characteristic for the switch from a previous deactivation setting to the determined deactivation setting and change, at a second time that is different from the first time, the activation characteristic for the switch from a previous activation setting to the determined activation setting.

摘要： A gas sensor having a heater, a receiver, and a space arranged between the heater and the receiver, is described, the heater being configured to generate a thermoacoustic sound wave propagating through the space by using a stimulation signal. The receiver is in this case configured to receive the thermoacoustic sound wave that has propagated through the space and to convert it into a reception signal that has a time-of-flight-dependent shift with respect to the stimulation signal and therefore information relating to the gas concentration in the space.

摘要： Systems, methods, and circuitries are provided for checking integrity of code received from an external memory. In one example, a system includes a non-volatile memory and a controller. The non-volatile memory includes a first partition configured to store first data corresponding to program code and a second partition configured to store second data corresponding to a copy of the first data. The controller that includes a processor and comparator circuitry. The comparator circuitry is configured to receive a portion of the first data and a corresponding portion of the second data, compare the portion of the first data to the portion of the second data, when the portion of the first data matches the portion of the second data, provide the portion of the first data to the processor, and when the portion of the first data does not match the portion of the second data, generate an alarm signal.
