Inhibition circuit with hysterisis and low consumption

摘要

The circuit has a comparator (10) with a negative input connected to a generator (20) producing a reference potential and a positive input connected to an output of a hysteresis circuit (30) producing a potential image of a supply potential (VDD). The circuit (30) has a diode (D2) and a reference current generator (50) connected in parallel between a common point on which the potential (VDD) is applied and the output.
