Circuit configuration for triggering a field effect transistor with a source-side load |
摘要 |
A circuit configuration for triggering a field effect transistor with a source-side load has a capacitor which is connected on one hand through a load path of the field effect transistor to a supply voltage and on the other hand both to a first charging device and to a first controllable switching device. The first switching device is connected between the capacitor and a gate terminal of the field effect transistor. A second charging device acts through a second controllable switching device to charge a gate-to-source capacitor of the field effect transistor. A comparator monitors a voltage at the gate terminal of the field effect transistor and makes the first switching device conducting when a predetermined value is reached.
