Circuit for detection and protection against short circuits for digital outputs |
摘要 |
A sense and protection circuit against short circuits for digital outputs, comprising a logic gating circuit of the exclusive OR type (EX1) which has a first input terminal connected to a signal input node (IN) and an output terminal which is connected to an input terminal of a signal level shifter output stage (B). A second logic gating circuit of the exclusive OR type (EX2) has a first input terminal connected to the input node (IN) and a second input terminal connected, through an inverting circuit (IN1), to an output terminal (OUT) of the output stage (B). A second input terminal of the first logic gate circuit is coupled to an output terminal of the second logic gate circuit through a comparator circuit (SCH1) and a delay circuit means (C,R,D).
