Abstract: The short-circuit detecting device includes a current generator for generating a current (IIN) of predetermined intensity, selectively into or out of the terminal (IN), and a first voltage comparator connected to the terminal (IN) and connected to the current generator in a manner such that the generator generates a current (IIN) in the inward direction and in the outward direction relative to the terminal (IN), respectively, when the voltage between the terminal (IN) and the ground is greater than a first level and less than a second level, respectively. The first level is greater than or equal to the second.
