<p>A high-voltage tolerant driver (200; 300) includes a plurality of output drive devices capable of tolerating an overvoltage, sustaining an electrical connection to an elevated voltage level, and producing an output voltage at an indigenous supply level. An initial pullup drive circuit (204) is coupled to the plurality of output drive devices and produces an initial elevated drive voltage to the plurality of output drive devices (235a-c, 275a-c). A sustain pullup circuit (260, 360) is coupled to the plurality of output drive device and produces a sustained output voltage at the indigenous supply level.</p> |
