Abstract
The monitoring of multiple supply voltages of an integrated circuit is done using a single external capacitor connected to a pin of the integrated circuit. Part of the multiple supply voltages are externally generated and part are internally generated. The internally generated supply voltages may include different voltages with different signs. A logic signal indicating that all the supply voltages have reached pre-established values before enabling functioning of the integrated circuit is generated after an initial soft start phase of the turn-on process.
