Abstract: Over-voltage tolerant circuits and methods are provided. In one embodiment, the circuit includes a pull-up transistor coupled to an I/O pad, a sensing circuit coupled to the I/O pad and to a voltage supply (Vcc), the sensing circuit configured to sense a voltage applied to the pad (Vpad), a latch coupled to the sensing circuit to retain an output of the sensing circuit, and a selection circuit coupled to the sensing circuit through the latch. The selection circuit includes a first bias circuit to apply Vcc to a well and gate of the pull-up transistor, a second bias circuit to apply Vpad to the gate and the well of the pull-up transistor, and a non-overlap circuit configured to ensure the gate and the well of the pull-up transistor is substantially always driven by either the first or the second bias circuit depending on the output of the sensing circuit.

Abstract: An enclosure is removably securable to a support member including a first part of a releasable fastener. The enclosure includes a panel of material sized to enclose the support member. A flexible flap is affixed to the panel, and a second part of the releasable fastener is affixed to the flexible flap. The second part of the releasable fastener is positioned for engagement with the first part when the panel encloses the support member. By affixing the second part of the releasable fastener to the flexible flap, the position of the fastener is adjustable to accommodate panel shrinkage, manufacturing tolerances and the like.
