Abstract

A drive device for a vehicle flap includes an electric motor (2) for driving the vehicle flap, and a supply switching circuit (3). The supply switching circuit (3) includes a first voltage source (9) for supplying current to the electric motor (2), a first electrical supply line (4) and a second electrical supply line (5). The first voltage source (9) is arranged between the first electrical supply line (4) and the second electrical supply line (5). The drive device also includes a control switching circuit (12) including a second voltage source (14) and a switching control device (13). The drive device includes a switching element (10) and a diode (11) connected between the first electrical supply line (4) and the second electrical supply line (5).
