  • High current limit trim apparatus and methodology
    Patent number: 10386876
    Abstract: A circuit protective system. The system has: (i) an input for sensing an operational voltage responsive to a current flowing through a transistor; (ii) circuitry for applying a forced voltage at the input; (iii) voltage-to-current conversion circuitry for outputting a reference current in response to the forced voltage at the input; (iv) circuitry for providing a reference trim current in response to a trim indicator; and (v) comparison circuitry for outputting a limit signal in response to a comparison of the reference current and the reference trim current.
    Type: Grant
    Filed: August 8, 2016
    Date of Patent: August 20, 2019
    Assignee: Texas Instruments Incorporated
    Inventors: Md. Abidur Rahman, Sualp Aras, Tri Cao Nguyen

  • Dynamic power saving pulse width modulated LED driver circuit
    Patent number: 8148914
    Abstract: In accordance with an aspect of the present invention, an LED driving circuit includes a digital-to-analog converter and a driving portion. The circuit is operable to turn off the digital-to-analog converter at times when the driving portion is not providing a high signal. As such the digital-to-analog converter will waste less energy.
