    Abstract: An LCD controller includes at least one I/O pad for providing an LCD drive voltage in an LCD mode of operation. I/O pad logic drives the at least one I/O pad responsive to a provided bias voltage. Voltage selection logic selects a higher voltage between an LCD drive voltage and an externally provided system voltage as a first voltage. Bias voltage logic selects one of the system voltage or the first voltage as the bias voltage for the I/O pad logic. The system voltage is selected as the bias voltage for the I/O pad logic in a non-LCD mode of operation for the I/O pad and the first voltage is selected for the bias voltage for the I/O pad logic in the LCD mode of operation for the I/O pad.

    Abstract: A system and method for an anti-pinch powered window system includes a window and a mechanical drive mechanism for raising and lowering the window. An electric motor drives the mechanical drive mechanism responsive to a command. A microcontroller unit generates the command responsive to a measured load current of the electric motor. A command to change direction of the window is generated responsive to a determination that the measured load current has exceeded a variable threshold level indicating that the window has stopped due to an obstruction. The variable threshold level is determined by the load current data stored within a memory.

    Abstract: The integrated system on a chip with LINBUS network communication capabilities includes processing circuitry for performing predefined digital processing functionalities on the chip. A free running clock circuit generates a temperature compensated clock that does not require a synch signal from external to the chip. A LINBUS network communications interface digitally communicates with off-chip LINBUS devices. Communication between said on-chip LINBUS communications interface and the off-chip LINBUS devices is affected without clock recovery. The LINBUS network communication interface has a time base derived from the temperature compensated clock which is independent of any timing information in the input data received during a receive operation. The temperature compensated clock further provides an on-chip time reference for both the processing circuitry and the LINBUS network communications interface.

    Abstract: Method and apparatus for combining outputs of multiple DACs for increased bit resolution. A method for providing an increased bit resolution to a data converter operable to convert digital information to analog values. A first current Digital-to-Analog (IDAC) converter is controlled to provide current to a first output node, the first IDAC having a first current step size associated with the Least Significant Bit (LSB) thereof. A second IDAC is controlled to provide current to the first output node, the second IDAC having a second current step size associated with the LSB thereof that is smaller than the first current step size. The combination of the first and second IDACs increases the bit resolution of the first IDAC when driving the first output node with the second IDAC.

    Abstract: SAR analog-to-digital converter with abort function. A method for increasing the throughput of a data converter decision is disclosed. First, a data conversion operation is initiated to convert analog signals on an analog input on a data converter to digital data by sampling the analog signals on the analog signal input and then converting the sampled analog signals to digital data with a predetermined data conversion algorithm in a data conversion operation. The digital output of the data converter is compared to a threshold voltage value. When the output of the data converter is determined by the step of comparing to meet a predetermined relationship relative to the threshold voltage, the data conversion operation is terminated prior to the complete execution of the data conversion operation on the sampled analog signals.
