  • 5 volt tolerant voltage regulator
    Patent number: 8593119
    Abstract: A voltage regulator circuit comprises an error amplifier for generating, an error signal responsive to a reference voltage in a feedback signal. A feedback circuit provides the feedback voltage signal to the error amplifier and a driver circuit provides regulated output voltage responsive to the input voltage in the error signal. Short circuit protection circuitry selectively protects transistors within the error amplifier, the feedback amplifier and the driver circuit responsive to a short circuit protection enablement signal.

  • Techniques for converting a plurality of channels continuously in an A/D converter
    Patent number: 6201492
    Abstract: A method and apparatus are used to continuously convert a plurality of analog signals on a corresponding plurality of physical channels using a circuit having analog to digital converter (ADC) components, a serial port interface, and a serial port controller. Logical channel information for one or more logical channels is stored in a register on the serial port controller. Each logical channel specifies one of the physical channels and conversion information for controlling the ADC components to produce a digital sample of the analog signal on the specified physical channel. At least one looping bit and at least one depth bit are also stored in a register on the serial port. The depth bit indicates a number of logical channels in one data scan. At least that number of logical channels are stored in the register. In response to a command bit indicating conversion mode, a quantity of data scans is output on a serial output pin of the serial port interface.
