Abstract
A voltage sequencing circuit for applying a plurality of voltages to an electrical system in a predetermined sequence charges the input capacitance of a pass device to set the timing between successive power applications in the system. In one embodiment, a current source coupled to the gate terminal of a field effect transistor (FET) pass device is enabled when a previous voltage in the predetermined voltage sequence has achieved a desired level. The output current of the current source then begins to charge the gate terminal of the FET. When the gate voltage achieves a predetermined reference level, a drive unit applies a voltage to the gate terminal that exceeds a threshold voltage of the FET. The FET then causes the next voltage in the predetermined voltage sequence to be applied.
