  • Capacitvive load overcurrent detection system and method
    Patent number: 9490623
    Abstract: An overcurrent detection circuit and method for one or more capacitive loads includes sensing current being supplied to the one or more capacitive loads to thereby generate a sensed current, and sensing a voltage rate of change across the one or more capacitive loads to thereby generate a differentiator output. The differentiator output is added to a fixed reference setpoint to thereby generate an overcurrent setpoint. The sensed current is compared to the overcurrent setpoint, and an overcurrent trip signal is supplied when the sensed current is greater than or equal to the overcurrent setpoint.
    Type: Grant
    Filed: November 18, 2014
    Date of Patent: November 8, 2016
    Assignee: HONEYWELL INTERNATIONAL INC.

  • Circuit with motor driver spike suppression
    Patent number: 8861145
    Abstract: A suppression circuit may be added to a motor driver circuit, which suppresses offset voltage and ringing in the output signal. The suppression circuit may include an RC circuit filter connected to a pin of a microchip providing a gating reference signal and a junction between high and low side MOSFETS connected to the microchip.
