Patent ID: 7724023

Claim:
An electrical circuit arrangement for electrically isolating at least one component within an electrical circuit device, comprising: a bond pad extension test pad; a controllable switch coupled to the bond pad extension test pad and configured for coupling to the at least one component, wherein the controllable switch includes at least one enable control input for enabling and disabling the controllable switch, wherein the controllable switch is configured in such a way that when the controllable switch is enabled the bond pad extension test pad is electrically connected to the at least one component and when the controllable switch is disabled the bond pad extension test pad is electrically isolated from the at least one component; and a control circuit coupled to the bond pad extension test pad and coupled to the enable control input of the controllable switch, wherein the control circuit is configured in such a way that, when a testing voltage is applied to the bond pad extension test pad, the control circuit enables the controllable switch, and when no testing voltage is applied to the bond pad extension test pad, the control circuit disables the controllable switch.
