Abstract
The present invention relates to an electronic power on reset circuit of the type including a comparator having at least two inputs and one output for receiving a first reference signal from a generator block and a second signal proportional to a supply voltage from a divider block and for producing an output initialization signal. Advantageously the output is connected to a third turn off enablement input of the comparator through the series of an inverter pair. The generator block and the divider block also include respective turn off enablement inputs connected downstream of the inverter pair.
