    摘要: A voltage monitoring arrangement including a number of comparison devices, which corresponds to a prescribed number of voltage ranges, compares the value of an input voltage with a reference voltage and outputs a prescribed signal if the input voltage is within one of the prescribed voltage ranges. The voltage monitoring arrangement has a latch circuit which, when a latch signal is applied, establishes which voltage range the input voltage is currently in when the latch signal is applied, resulting in the arrangement having automatic voltage range reduction. The voltage monitoring arrangement has a monitoring unit which outputs a predetermined signal if the input voltage is outside the voltage range which exists when the latch signal is applied.

    摘要: The circuit contains a series regulator with an FET. A capacitor and a further FET, which is provided as a transfer gate and is driven by the POR signal, are connected in series between the source terminal, to which the external supply voltage is applied, and the gate connection. When the external voltage is applied, the FET opens, with the transfer gate switched on, corresponding to the charging of the capacitor which now takes place. Because this charging process takes a certain amount of time, overshoots in the internal voltage are prevented.
