Abstract

A circuit arrangement includes a microcontroller having a first analog-to-digital converter whose input is connected to the output of a first multiplexer whose output is connected to a first comparison device for comparing reference voltages, and a first serial interface circuit connected to the first comparison device. A voltage generating circuit includes a second analog-to-digital converter whose input is connected to the output of a second multiplexer whose output is connected to a number of registers, which are connected to a safety value generator and store digital values together with a respective safety value, and a second serial interface circuit connected to the registers. The first and second serial interface circuits are connected to each other for communication of the microcontroller with the voltage generating circuit, the first interface circuit being connected to a second comparison device for comparing supply voltages and/or currents with desired voltages and/or desired currents.
