Current sensing by using aging sense transistor

A current sense circuit comprising:

• a power transistor having a power transistor control node that controls whether current flows from a power transistor input node to a power transistor output node;
• a sense transistor having a sense transistor control node that controls whether current flows from a sense transistor input node to a sense transistor output node, the sense transistor control node connected to the power transistor control node;
• and
• a pull-up component connected between the power transistor input node and the sense transistor input node, the pull-up component being structured such that, when power is provided to the pull-up component and when the power transistor and the sense transistor are off, the pull-up component is structured to cause a sense transistor input node voltage at the sense transistor input node to be at least twenty percent of a power transistor input node voltage at the power transistor input node.
