| 摘要 |
The invention relates to a protection circuit for a driver circuit T, activating a power semiconductor LH, which driver circuit is connected between a positive and a negative operating voltage UB and which has at least one input UE which exhibits a voltage difference with respect to the positive and/or negative operating voltage. A series circuit of a Zener diode and a current limiting resistor RV connected between the positive and the negative operating voltage is provided, in which arrangement the voltage difference can be set to a constant value via the Zener diode Z. <IMAGE> |
