摘要： For use in a regulator, a driver (200) has a first transistor pair (203, 204) for alternatively pulling a drive line (OUT, 196) to magnitudes in a limited magnitude range between first and second reference lines (191, 192) depending on an input signal (IN, 195). Parallel to the first pair (203, 204), a second transistor pair (212, 210) alternatively pulls the drive line (OUT, 196) substantially to the reference lines (191, 192). The second pair (212, 210) is controlled by a comparator arrangement (120, 130) comparing the input signal to first (REF—1) and second (REF—2) reference signals and activating the second pair (212, 210) substantially only when the signal (OUT) on the drive line (196) driven by the first pair reaches a magnitude limit. The transistors (203, 204) of the first pair are arranged as emitter followers and the transistors (212, 210) of the second pair are arranged as switched current sources.

摘要： A system (200) comprises a regulator (250), a battery unit (220), a voltage sensitive circuit (210, e.g., memory circuit) and a switchable sensor (280). The battery unit (220), the memory circuit (210) and the switchable sensor (280) are parallel coupled to terminals (266 and 264) of the regulator (250). The switchable sensor (280) itself has a serially coupled voltage sensor (230) and switch (240). In a first operating mode, the regulator (250) provides a voltage V.sub.2 to the memory circuit (210) and to the switchable sensor (280). The switch (240) is closed. The voltage sensor (230) measures the voltage V.sub.2 and communicates the result to the regulator (250) via a signal input (267). In a second operating mode, the regulator (250) does not provide the voltage V.sub.2. The switch (240) is open. The battery unit (220) provides a voltage V.sub.4 to the memory circuit (210), but not to the voltage sensor (230). Parasitic current backflow from the battery unit (220) to the voltage sensor (230) is thereby substantially avoided.

摘要： A current sense circuit (14) is provided which receives a signal indicative of output current flow of an up/down DC-DC converter during up-conversion and down-conversion modes. The current sense circuit provides a logic signal (CS) indicative of the rate of change of the current flow for both modes of operation. A comparator (42) receives a selectable voltage reference generated by voltage reference (36,38,50). A first voltage reference is selected during an increasing current flow (CS=logic high) and a second voltage reference is selected during a decreasing current flow (CS=logic low), thereby regulating the output current (IL) to a fixed average value. If the length of time during continuous current flow of converter (10) exceeds a predetermined amount of time, a signal (FAULT) is issued and externally processed, which subsequently disables converter (10) by an external signal (ENABLE).

摘要： An arrangement (100) has a low voltage circuit (196') on a first doped well (110) and a high voltage circuit (197') on a second doped well (120) integrated into a common semiconductor substrate (105). The first well (110) laterally extends along a surface (106) of the substrate (105) to provide a voltage drop (.vertline.V.sub.LARGE .vertline.) between a first end (111) and a second end (112) so that potential differences between the circuits (196', 197') are substantially isolated. The low voltage circuit (196') controls a current from the second end (112) to provide a variable potential (by .vertline.V.sub.SMALL .vertline.) at the second end (112) which is communicated to other parts (193') of the second circuit (197') by a connection (150). The wells (110, 120) are spaced to provide isolation for potential magnitude changes between the second end (112) of the first well (110) and the second well (120) which are invoked by the first circuit (196').

摘要： An integrated voltage converter (104) includes a first switch (S1) that turns on with a value of a control signal (UP/DOWN) to generate a coil current (ICOIL) at a node (208) when an output voltage (VOUT) of the voltage converter is greater than a reference voltage (VBATT−&Dgr;V). A second switch (S2) coupled to the node turns on with another value of the control signal to generate the coil current when the output voltage is less than the reference voltage. The coil current discharges through the second switch to an output (202) of the voltage converter to develop the output voltage.
