Circuit for controlling, monitoring, and terminating control of, inductive loads, particularly magnetic valves in an anti-lock control system

An inductive-load circuit for controlling and monitoring inductive loads comprising;

• at least one circuit amplifier (T1) for coupling at least one inductive load (MV1) in a circuit with a voltage source (B);
• a control circuit (106, 105, 102) coupled to a control terminal of said at least one circuit amplifier;
• a microcomputer (MC) coupled to said control circuit of said at least one circuit amplifier for applying signals to said control terminal of said at least one circuit amplifier via said control circuit for thereby controlling said at least one circuit amplifier to thereby couple the at least one inductive load in the circuit with the voltage source, said microcomputer being further coupled to said at least one circuit amplifier via a monitoring circuit (101, 103);
• said monitoring circuit (101, 103) for monitoring a voltage status at an interface (VP1) of the at least one circuit amplifier and the inductive load, wherein said monitoring circuit includes a threshold monitor (103) coupled to said interface for detecting the voltage status at the interface;
• wherein said inductive load circuit further includes a first circuit means (108) coupled between said threshold monitor and said control circuit for causing said control circuit to terminate control of the at least one circuit amplifier by the microcomputer via said control circuit when the threshold monitor detects a voltage at said interface outside of a threshold range thereof while said at least one circuit amplifier is being controlled by said microcomputer to couple the at least one inductive load in the circuit.
