ABSTRACT:
A circuit in which an n-channel MOS transistor is employed between load and the positive pole of an operating voltage source has the following drive circuit: parallel to the switching transistor and the load there is connected an RC-network. Both capacitors have a common junction at gate potential and are voltage limited. The gate is connected to the output of the inverter which can be switched between the source potential U.sub.S1 and U.sub.S1 +U.sub.C1. A diode path is connected in parallel with C1 and in parallel with C2 there is an oscillator having a push-pull output which is connected through a capacitor between D3 and D4. Such a drive requires no external auxiliary voltage, allows for static and dynamic circuit drive as well as randomly high drive voltages and permits integration with well known techniques.
Principal application area: Network circuit components, actuator setting, motor controls, switching of loads in control technology and in motor vehicles.
