This power-on reset (POR) control circuit eliminates the possibility of prematurely turning-on "card" logic until both the power supply and system POR control line are stable enough for error-free operation. This is a precision circuit that insures that all supplies are within 18% of their final value for extremely slow voltage ramp ups. Typically, they are at their final value.
