Abstract: A system is described for the diagnosis of a driver (D) of the type adapted to detect one or more circuit anomalies which can occur in the said driver, including:

voltage comparator circuits (10, 20) adapted to generate diagnostic logic signals (F 1 , F 2 , F 3 ) each indicative of the existence of a corresponding type of anomaly; and
a coding circuit (M, SM) adapted to receive these diagnostic signals (F 1 , F 2 , F 3 ) and to output information relating to an overall operating state of the circuit. The coding circuit (M, SM) includes a first portion adapted to provide at its output first logic signals (SHB, SHG, OL) indicative of the last anomaly occurred since a system reset operation, and a second portion for coding such first logic signals (SHB, SHG, OL). The second portion includes a sequential logic network (SM) adapted to:


receive the first logic input signals (SHB, SHG, OL) and at least one second logic signal (IN) indicative of the current operating phase of the driver (D); and
achieve, as a function of the said first and second logic signals (SHB, SHG, OL; IN) a stable internal state such as to determine at the output information in the form of an N bit coded word representative of an occurred anomaly, of a condition of absence of anomaly in the current operating phase, or of a condition of absence of anomaly in any operating phase.

Abstract: A circuit and a process for diagnosis of the earth wiring in a circuit module comprising a plurality of sections (11, 12), each with a respective reference conductor (GND 1 , GND 2 ), capable of being connected separately to the common earth conductor (GND CH ) through a respective electrical path is described.
The circuit comprises a plurality of branches each coupled in series with a respective electrical connection path to the common earth conductor (GND CH ); a circuit for supply of a control current (I P ) to these branches; and a plurality of detection resistances (R S1 / R S2 ) each associated with respective branch for detecting a current flowing in it towards the common earth conductor (GND CH ). The diagnosis process provides for supplying a control current (I P ) to the said diagnosis circuit branches and detecting the current flowing in them following supply of this current. The flow of current in these branches following supply of the control current (I P ) is indicative of the electrical continuity of the respective electrical paths to the earth common conductor (GND CH ) .
