(EP846992-A1)      The electrical circuit has several power semiconductor end stages (51-5n) driving associated loads (71-7n) and influenced by a microcomputer (1) to which they are connected via a circuit complex (41-4n) contg. a computer system and interfaces (31-3n) for protecting and driving the power semiconductor end stages.    The computer system is influenced by a physical parameter for each power semiconductor end stage. Each circuit complex responds to impermissible, highly time critical variations in the physical parameter directly via the interface hardware. It responds to impermissible, less time critical variations via a programmable protection function.    USE -   For controlling servo-pumps, fuel pumps and fan drives as well as bulbs for head- and indicator-lights.    ADVANTAGE -   Ensures optimal protection of power semiconductor end stages and connected load circuits.
