Abstract
An apparatus and method for overload protection circuit. The apparatus includes a current limiting circuit that is coupled to a first node. A switching element is coupled in series to the current limiting circuit and to a second node. A voltage measurement circuit is coupled to the first and second nodes and is used for measuring a voltage across the first and second nodes. A control mechanism is coupled to the voltage measurement circuit and the switching element. The control mechanism opens the switching element when the voltage exceeds a predetermined value.
