Abstract: A motor system with an input for coupling to a motor control signal that, when presented in a predetermined state, indicates a motor receiving power should be disabled from rotating. The system also includes controller circuitry for providing a disabling signal to motor rotation, independent of processor software control signaling and the power, in response to the control signal.

Abstract: An electronic circuit for controlling a power switch having a gate input, includes a signal generator configured to generate a gate driver input signal. The gate driver input signal has a first voltage during a first period of time, a second voltage during a second period of time, and toggles between the first voltage and the second voltage during a third period of time. The electronic circuit also includes a gate driver configured to receive the gate driver input signal and to provide a gate driver output signal based on the gate driver input signal. The signal generator is configured to cause the gate driver input signal to toggle during the third period of time such that the gate driver output signal has a third voltage during the second period of time, and an intermediate voltage that is less than the third voltage during the third period of time.

Abstract: A circuit includes a solid-state relay, a rectifier, and a current transformer-based power supply. The rectifier is adapted to be coupled to the solid-state relay. The rectifier is configured to provide a voltage to an output terminal responsive to the solid-state relay being in an off state. The current transformer-based power supply is coupled to the rectifier and is adapted to be coupled to a transformer. The current transformer-based power supply is configured to provide a voltage to the output terminal responsive to the solid-state relay being in an on state.

Abstract: An apparatus and method of detecting movement of a plunger of the solenoid includes detecting a peak (IPEAK) in a current signal applied to a coil of the solenoid. A predetermined threshold is added to the current signal applied to the coil of the solenoid to generate a level shifted signal. The level shifted signal and the peak signal are compared to detect movement of a plunger of the solenoid.
