Abstract
A driver circuit having series-connected high-side and low-side MOS switches with MOS transistors for driving a load, a temperature-limiting circuit and a current-limiting circuit, which is assigned to one of the two MOS transistors. In order to balance power losses between the high-side and low-side MOS switches, provision is made for the gate of the MOS transistor without the current-limiting circuit to be connected to ground via a voltage generator, whose voltage corresponds to a maximum drive voltage for this MOS transistor.
