Device for detecting a reduction in a supply voltage |
摘要 |
A circuit for detecting a reduction below a threshold value in a supply voltage provided to storage devices integrated into a semiconductor. A comparator is coupled between a voltage supply line and a signal ground and has a first or reference input and a second or test-signal input. A generator of a stable voltage reference has an output coupled to the first input and a divider of the supply voltage coupled to the second input of the comparator. A circuit means is arranged to feed the voltage supply line with the higher of the supply voltage and a programming voltage also provided to the storage devices.
