Abstract
The disclosure relates to integrated circuits and, more particularly, to a power-on-reset circuit. The proposed circuit produces an inhibition signal when the power is turned on, this signal being interrupted after the supply voltage Vcc has reached a first threshold (VS1) (VS1). Furthermore, the circuit has means to re-trigger the inhibition signal when the supply voltage drops by a certain value, in doing so even if the supply voltage remains above the first threshold. The reliability of the integrated circuit is improved. The disclosed circuit is particularly applicable to the inhibition of the writing circuit of an EEPROM memory.
