Abstract: A current limiting load switch for bridging supply Vss and load with a reference voltage VRdt dynamically generated by a VRdt-generator is proposed. It includes: A pair of power FET and sense FET interconnected in split-current configuration. The FET pair develops a load voltage while limiting load current Iload to a preset maximum Imax. The FET pair is sized to draw device currents Ipower and Is with RATIOI=Is/Ipower<<1. The sense FET high-side terminal is coupled to Vss through a sense resistor Rsense developing a sense voltage Vs=Is×Rsense. A current limiting amplifier with inputs connected to VRdt and Vs and output controlling FET pair closing a current limiting feedback loop. The VRdt-generator dynamically adjusts VRdt concurrent and compensatory with an undesirable effect of changing RATIOI caused by the sense FET operational transition thus eliminating a transitional overshoot of Iload beyond Imax.

Abstract: A semiconductor package assembly may include a lead frame having a die bonding pad and plurality of leads coupled to the first die bonding pad. A vertical semiconductor device may be bonded to the die bonding pad. The device may have a conductive pad electrically connected to one lead through a first bond wire. An electrically isolated conductive trace may be formed from a layer of conductive material of the first semiconductor device. The conductive trace provides an electrically conductive path between the first bond wire and a second bond wire. The conductive path may either pass underneath a third bond wire thereby avoiding the third bond wire crossing another bond wire, or the conductive path may result in a reduced length for the first and second bond wires that is less than a predetermined maximum length.

Abstract: Multiple channel maps are embedded in a television transmission and the appropriate-channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.

Abstract: A remote controller includes a display screen (12) and a speaker (14). The remote controller receives and stores transmitted television program information, preferably including an electronic program guide (EPG). Preferably the program information is transmitted over a wireless paging system (FIG. 6) at a preferred frequency of about 900 MHz. A microcontroller (46) in the controller includes a digital signal processor for sorting and storing the retrieved program information. In response to a viewer command input through a keypad (15) on the remote controller, the microcontroller selectively retrieves and displays at least a portion of the program information on the display screen of the remote controller. The display changes as the viewer changes channels or scrolls through the EPG. The remote controller also has a voice message function. When the voice message function is activated, the microcontroller retrieves and processes a voice message for announcement through the speaker.
