ABSTRACT:
An integrated circuit having a voltage generator supplying a determined voltage, a voltage-limiting circuit arranged at the output of the voltage generator, the voltage-limiting circuit having at least one PN junction formed by a diode-arranged MOS transistor, the PN junction having a breakdown voltage defining a threshold for triggering the voltage-limiting circuit as from which the PN junction is on by avalanche effect, at least one load in series with the PN junction for limiting an avalanche current passing through the PN junction when the PN junction is on, and at least one switch in parallel with the PN junction and the load, the switch arranged in the open state when the PN junction is off and to be in the closed state when the PN junction is on.
