Claim Text:
1. An over-voltage protection circuit, comprising: an input; an output; a potential divider connected to the input; a first switch arrangement connected to the potential divider and having a select input for receiving a first select signal (SELA); a second switch arrangement connected between the potential divider at a first node and the output, and having a control terminal connected to the potential divider and the first switch arrangement at a second node; and a delay circuit connected between the control terminal of the second switch arrangement and the second node, wherein in a first mode of operation, the first switch arrangement enables the potential divider in response to receipt of the first select signal and closes the second switch arrangement, such that a voltage at the first node is transferred to the output at a third node, and in a second mode of operation, in response to the first select signal, disables the potential divider.
