  • Patent number: 10530352
    Abstract: The disclosure is directed to implementing a gradual power transition, in digital and mixed-signal power converters. A “soft start” smooths an abrupt power change in the output of a power converter such as when the power converter starts up after turning on the power to a device. A power converter may receive a digital control signal that includes a command to start up, as well as includes a power level set point. This disclosure includes a circuit that receives the digital control signal and outputs a modified control signal to the power converter that causes the power converter to gradually change the power output of the power converter until the power output reaches the power level set point. The circuit dynamically determines a step size, length of time of each step and other parameters based on characteristics of the input digital control signal.

  • Patent number: 9970982
    Abstract: An apparatus for providing an output parameter includes an output parameter generator circuit configured to determine a value of an output parameter repeatedly. The output parameter generator circuit includes at least one circuit block mandatory for the determination of a value of the output parameter. Further, the apparatus includes an output interface circuit configured to transmit the output parameter repeatedly to a receiver and a test circuit configured to test a basic functionality of the at least one mandatory circuit block of the output parameter generator circuit repeatedly. The at least one mandatory circuit block of the output parameter generator circuit is unavailable for the determination of a value of the output parameter during the basic functionality test.

  • Patent number: 9846191
    Abstract: Integrated circuit systems, such as sensor systems, having on-board-diagnostic (OBD) circuits for the detection of errors presenting internal to the systems are disclosed, along with related methods. In one embodiment, an ADC multiplexer receives analog output readback from an output driver and provides a signal triggering an OBD circuit for internal error indication performed completely independent of digital-to-analog converters (DAC) and output drivers, which can be the point of failure.
