  • Overcurrent protection circuit
    Patent number: 7061739
    Abstract: Disclosed is an overcurrent protection circuit including an overcurrent trip and a switching element. A switched current passing through the switching element can be detected by the overcurrent trip and the switching element can be tripped to open if the switched current fulfils a tripping requirement. A current limiter is series-connected downstream of the switching element.
