    摘要: The invention relates to a driver circuit with a circuit node (10), at least two first transistors (P1, P2), the load sections of which are switched in series and connect the circuit node (10) with a first voltage (U10), at least two second transistors (N1, N2), the load sections of which are switched in series and connect the circuit node (10) with a reference potential, and a control circuit (P3–P6, N3, D1–D4, R1, 16), which is formed in order to regulate at least a first control voltage (Up2) on at least one transistor (P2) of the at least two first transistors (P1, P2) and at least a second control voltage (UN2) on at least one transistor (N2) of the at least two second transistors (N1, N2) dependent on a voltage at the circuit node (10).
