Circuit arrangement for protection against electrostatic discharge and voltage regulating device having a circuit arrangement |
摘要 |
A circuit arrangement for protection against electrostatic discharge for a field-effect transistor is disclosed. The arrangement includes a first and a second controllable path each having a control terminal. The control terminals of the controllable paths are coupled to a source terminal of the field-effect transistor. A first terminal of the first controllable path is connected to a control terminal of the transistor, and a first terminal of the second controllable path is connected to a bulk terminal of the unipolar transistor. Second terminals of the controllable paths are connected to the drain terminal. A voltage regulating device includes the circuit arrangement and a comparator configured to generate a control signal in a manner dependent on a difference between two signals applied thereto. A control output of the comparator is coupled to the control terminal of the transistor.
