ABSTRACT:
A device is provided for resetting an integrated circuit generating a reset signal after a power supply voltage drop to a very low level has been detected. Such a device includes at least one control means, the state of which (conducting or non-conducting) is controlled by a control voltage equal to the difference between the power supply voltage and a predetermined offset voltage, such that if the control voltage is less than or equal to a threshold, the control means authorizes activation of the means for generating a reset signal.
