Voltage sequencing arrangements providing first and second voltages sequenced to each other in time

Abstract

A voltage sequencer includes an input terminal and an output terminal and a control element connected between the input an output terminals. A capacitive element is connected between the output terminal and a first voltage and a resistive element is connected between the output terminal and a second voltage. The control element selectively controls charging and discharging of the capacitive element such that, upon the voltage at the input terminal increasing from the first voltage to a nominal value, the output terminal voltage increases to a nominal value in a first predetermined period of time and upon the voltage at the input terminal decreasing from the nominal value to the first voltage, the output terminal voltage decreases to the first voltage value in a second predetermined period of time, the first predetermined period of time being different from, for example, substantially greater than, the second predetermined period of time. The capacitive element may be a capacitor and the resistive element may be a resistor. The first voltage may be a ground potential while the second voltage may be a positive potential with respect to the first voltage.
