If the circuit determines that the terminal is floating or is substantially floating, then the circuit sets an operational characteristic of a portion of the circuit (for example, sets a maximum current with which the circuit charges a battery) to have a value that is a function of a resistance of an external resistor coupled to the terminal. If no external resistor is present, then the terminal is floating and the operational characteristic is set to have a zero value. The terminal and circuit are particularly suited to use in a USB battery charger. | 02-05-2009 |
20090134911 | Drive method for driving element having capacity impedance, drive device, and imaging device - Three devices such as electric charge-coupled devices are each included in one of three phase impedance circuits composing a 3-phase LC resonance circuit as a device having a capacitive impedance. A driver circuit applies either of a logic level of 0, a high-impedance level or a logic level of 1 to each of nodes Node_A, Node_B and Node_C of the phase impedance circuits so as to result in sequential transitions of a state of resonance among the phase impedance circuits. In an operation to drive the phase impedance circuits, either of the logic level of 0, the high-impedance level and the logic level of 1 is applied to each of the nodes so as to sustain a phase difference of 2π/3 between the phase impedance circuits. In this way, the logical levels and the phases of the logical levels are assigned to the nodes in such a way that the logical levels do not overlap with each other at any timings each corresponding to a point of time. Thus, a driving apparatus for driving the devices each having a capacitive impedance is capable of reducing the power consumption. | 05-28-2009 |
