Abstract
A circuit has circuit amplifiers (T1, T2) and inductive loads (MV1, MV2) with the circuit amplifiers being controlled by control signals provided by a microcomputer (MC). The circuit accomplishes this control while monitoring a load circuit, comprised of the circuit amplifiers and the loads, and terminates control of the circuit amplifiers, without assistance of the controlling microcomputer, upon occurrence of incorrect voltages in the load circuit. Thus, the circuit of this invention allows particularly fast termination of control of the load circuit upon the appearances of critical voltages and also allows the monitoring of the load circuits by the microcomputer in a particularly uncomplicated manner.
