    Abstract: An electronic circuit is for switching a power transistor having a drain coupled to a drain node, a source coupled to a lower voltage supply, and a gate coupled to a gate node. The electronic circuit includes first current generation circuitry to generate a first current to flow into the gate node in response to assertion off an ON signal, the first current being substantially constant. Second current generation circuitry generates a second current to flow into the gate node in response to deassertion of an OFF signal, the second current being inversely proportional to a gate to source voltage of the power transistor. First comparison circuitry compares a drain voltage at the drain node to a reference voltage, and activates third current generation circuitry to generate a third current to flow into the gate node when the drain voltage is less than the reference voltage.

    Abstract: A method of starting a permanent magnet synchronous motor (PMSM) with field oriented control (FOC) includes: opening a first control loop of the PMSM; setting a first direction for a first current component of the PMSM; aligning a rotor of the PMSM to the first direction; after aligning the rotor, setting a second direction for the first current component, where the second direction is rotated from the first direction by 90 degrees; after setting the second direction, starting the rotor while the first control loop of the PMSM remains open; after starting the rotor, increasing a rotation speed of the rotor by operating the first control loop in a first closed-loop mode; and after increasing the rotation speed of the rotor, controlling the rotation speed of the rotor by operating the first control loop in a second closed-loop mode different from the first closed-loop mode.

    Abstract: A device includes a circular buffer, which, in operation, is organized into a plurality of subsets of buffers, and control circuitry coupled to the circular buffer. The control circuitry, in operation, receives a memory load command to load a set of data into the circular buffer. The memory load command has an offset parameter indicating a data offset and a subset parameter indicating a subset of the plurality of subsets into which the circular buffer is organized. The control circuitry responds to the command by identifying a set of buffer addresses of the circular buffer based on a value of the offset parameter and a value of the subset parameter, and loading the set of data into the circular buffer using the identified set of buffer addresses.
