METHOD AND SYSTEM FOR SHORT CIRCUIT DETECTION IN A SENSOR

摘要

A method of detecting a short circuit affecting a sensor, at least one terminal of the sensor being connected to a bias resistor, includes: applying to at least one bias resistor at least one test bias voltage having at least one predefined characteristic that is different from a corresponding characteristic of a nominal bias voltage of the resistor; measuring a resulting differential voltage across the terminals of the sensor; and as a function of at least one characteristic of the measured differential voltage corresponding to the predefined characteristic of the test bias voltages, determining whether the sensor presents a short circuit.
