ABSTRACT:
A plurality of output drive devices are capable of tolerating an overvoltage produced by an electrical connection with an external device operating in a high-voltage supply realm. The drive devices are capable of sustaining a continuous electrical connection to the elevated voltage levels and produce communications at an output voltage level equal to the supply voltage indigenous to the device. A high-voltage tolerant driver 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 is coupled to the plurality of output drive devices and produces an initial elevated drive voltage to the plurality of output drive devices. A sustain pullup circuit is coupled to the plurality of output drive devices and produces a sustained output voltage at the indigenous supply level.
