摘要： An integrated circuit chip having formed thereon a voltage control circuit supply adapted to provide one of a pair of voltages selectively in accordance with an operating mode of the circuit. The circuit includes a comparator circuit fed by the pair of voltage sources. A first switch is controlled by the comparator circuit. A first one of the pair of voltage sources is fed through a second switch which may be a transistor or a diode. An input of the first switch is fed to a second one of the pair of voltage sources. The comparator circuit is arranged to place the switch in a non-conducting condition in one operating mode to couple the first one of the pair of voltage sources to the output of the circuit while isolating the second one of the pair of voltage sources supplies from the output of the circuit during such operating mode, and to place the switch in a conducting condition in the other one of the operating modes to de-couple the first one of the pair of voltage sources from the output of the circuit while coupling the second one of the pair of voltage sources to the output of the circuit output during such other one of the operating modes. The standby voltage control circuit allows a higher voltage (e.g., +12 volts) to be power-down while a lower voltage (e.g., +5 volts) is still applied without forward biasing any internal diodes and thus keeping currents low. Such is accomplished by the internal second switch, the comparator, and the switch. In normal operation mode, the second switch is conducting; in power-down operation mode, the second switch is non-conducting the comparator closes the first switch connecting the output of the standby voltage control circuit to the lower voltage.

摘要： An input protection device is provided for protecting a circuit structure which is coupled to a first node, the device comprising a first lightly-doped region of P-type material with a lightly doped well of N-type material formed in it. Two regions of heavily doped N-type and P-type material, which are electrically connected to the first node, are formed in the well of N-type material. A third heavily doped region of N type material is formed in the first lightly-doped region of P-type material and is electrically connected to a reference node. In a first aspect of this invention, the third heavily doped region of N type material is formed in a second well of N-type material, which in turn is formed in the first lightly-doped region of P-type material. In this first aspect of the invention a further region of heavily doped P-type material is formed in the second well of N-type material, this further region of heavily doped P-type material being electrically connected to the reference node. In a second aspect to the invention, a further region of heavily doped P-type material is formed in the first lightly-doped region of P-type material. In a third aspect to the invention, the third heavily doped region of N type material is formed in a second well of N-type material, which in turn is formed in the first lightly-doped region of P-type material. In this third aspect of the invention a further region of heavily doped P-type material is formed in the second well of N-type material, this further region of heavily doped P-type material being electrically connected to the reference node, with a further region of heavily doped P-type material formed in the first lightly-doped region of P-type material. Accordingly, an input protection device for protecting pins of an integrated circuit is described having both bipolar and unipolar characteristics. The input protection device may be constructed as a discrete device or as part of an integrated circuit and provides for breakdown voltages in excess of a supply voltage to an integrated circuit. The characteristics, in particular the breakdown voltage, of the input protection device are alterable by adjusting its layout, in contrast to a known method of altering such characteristics by altering doping levels.
