  • Patent number: 12179617
    Abstract: Examples of contactor controllers, systems and methods enable quick-turn-off (QTO) using an output voltage of a contactor controller when its supply voltage is below a threshold but does not interfere with QTO when sufficient supply voltage is available. In an example, when VM loss occurs, a high-side (HS) clamp of a contactor controller is disabled, and a low-side (LS) clamp current is generated using the output voltage. The LS clamp current may be adjusted to achieve a desired QTO voltage. In another example, a HS clamp is disabled and the charging of the gate of a LS field-effect transistor (FET) is enabled only when the output voltage increases above a power-off QTO threshold (less than the LS clamp voltage); the QTO voltage is set by a voltage detection and comparison circuit of the contactor controller.

  • Patent number: 12172374
    Abstract: A layer of additive material is formed in a circular printing area on a substrate using additive sources distributed across a printing zone. The additive sources form predetermined discrete amounts of the additive material. The substrate and the additive sources are rotated with respect to each other around a center of rotation, so that a pattern of the additive material is formed in a circular printing area on the substrate. Each additive source receives actuation waveforms at an actuation frequency that is proportional to a distance of the additive source from the center of rotation. The actuation waveforms include formation signals, with a maximum of one formation signal in each cycle of the actuation frequency. The formation signals result in the additive sources forming the predetermined discrete amounts of the additive material on the substrate.

  • Patent number: 12170256
    Abstract: A method for fabricating a semiconductor product includes forming a dielectric layer over a top level metallization layer of a semiconductor process wafer. The dielectric layer is patterned using a grayscale mask process to define a contact pad opening in the dielectric layer, thereby producing a patterned dielectric layer in which the contact pad opening is aligned to a contact pad defined in the top level metallization layer. A metal layer is deposited over the patterned dielectric layer, including within the contact pad opening. A portion of the metal layer is removed by a chemical mechanical polishing (CMP) process, with a remaining portion of the metal layer having a sloped sidewall.

  • Patent number: 12168401
    Abstract: A regenerative braking controller for an AC motor. To determine an electromagnetic torque for slowing or stopping the motor, the regenerative braking controller accesses a lookup table to retrieve a braking torque value corresponding to a current estimate of rotor velocity. The retrieved braking torque may correspond to a maximum or minimum torque level at which regenerative braking will occur at the current rotor velocity, or to a torque level at which charging current during regenerative braking will be maximized. If an external mechanical brake is present, the regenerative braking controller can forward an external braking torque signal to a controller so that the mechanical brake can apply the remainder of the braking force beyond that indicated by the regenerative braking torque. A method for establishing the braking torques to be stored in the lookup table is also disclosed.

A first current source is enabled deliver a constant current to the pin during SS. A second current source is enabled to generate a reference voltage at the source of the second transistor during OCL, which reference voltage is transferred to the pin by the source follower configuration. A comparator controls the switches to transition from SS to OCL sensing.
