METHOD FOR PROVIDING OVER CURRENT PROTECTION AND CIRCUIT

A method and circuit for protecting against an over current condition. A conduction time of one or more transistors is reduced during the over current condition. The conduction time is reduced in an amount that is an increasing function of the amount of the over current. The conduction time may be r...

More Information
Summary:A method and circuit for protecting against an over current condition. A conduction time of one or more transistors is reduced during the over current condition. The conduction time is reduced in an amount that is an increasing function of the amount of the over current. The conduction time may be reduced proportionally to the excess current. La présente invention concerne un procédé et un circuit de protection contre un état de surintensité. Un temps de conduction d'un ou de plusieurs transistors est réduit durant l'état de surintensité. Le temps de conduction est réduit d'une valeur qui est une fonction croissante de la valeur de la surintensité. Le temps de conduction peut être réduit proportionnellement à la surintensité.
