Abstract

A semiconductor circuit for an electronic unit having at least one microcontroller comprises at least one voltage regulator for providing, from a first supply voltage, at least one second supply voltage for the microcontroller and for circuits of the unit which cooperate with the microcontroller. The circuit further comprises, in monolithic form, a transceiver unit having transmitting and receiving device for coupling a microcontroller to the two-wire bus. This monolithic construction may additionally comprise watchdog functions, various wake-up functions and an interface via which a serial data exchange with the at least one microcontroller is possible. Furthermore, it may have an apparatus for determining, throughout the network, bus subscribers having reference-ground potential faults and for quantifying such faults.
