Abstract:
A voltage sequencer apparatus comprising an input terminal and an output terminal, a control element connected between said input and output terminals, a capacitive element connected between said output terminal and a first voltage, and a resistive element connected between said output terminal and a second voltage, wherein said control element selectively controls charging and discharging of said capacitive element such that, upon input terminal voltage increasing from said first voltage to a nominal value, said output terminal voltage increases to a nominal value in a first predetermined period of time and wherein, upon input terminal voltage decreasing from said nominal value to said first voltage, said output terminal voltage decreases to said first voltage in a second predetermined period of time, said first predetermined period of time being different from said second predetermined period of time; anda voltage regulator controllable by at least said output terminal voltage.
