Abstract
An integrated circuit having an error detection circuit for detecting an error in a connection with an electrical component. The error detection circuit includes a control circuit, a terminal arranged to connect the electrical component, and a driver coupled to the terminal and arranged to be controlled by the control circuit. The driver is arranged to drive a current on receipt of a control signal (Vctl) from the control circuit and the control circuit is further arranged to receive in response to the current a measurement signal via the terminal, to determine based on a characteristic of the measurement signal a possible error and to communicate an error signal based on the determining.
Claims14
An integrated circuit comprising
- a voltage regulator configured to output a regulated voltage signal,
- an error detection circuit for detecting an error in a connection of an electrical component, said error detection circuit configured to receive as input said regulated voltage signal and comprising
- a control circuit,
- a terminal arranged to connect the electrical component to the input,
- a driving means coupled to said terminal and arranged to be controlled by said control circuit,
- whereby said driving means is arranged to drive a current on receipt of a control signal from said control circuit and whereby said control circuit is further arranged to receive in response to said current a transient signal via said terminal, to determine based on a characteristic of the transient signal a possible error and to communicate an error signal based on said determining.
