Abstract
Systems and techniques for applying voltage biases to gates of driver circuitry of an integrated circuit (IC) based on a detected bus voltage, IC supply voltage, or both are used to mitigate Electrical Over-Stress (EOS) issues in components of the driver circuitry caused, for instance, by high bus voltages in serial communication systems relative to maximum operating voltages of those components. A driver bias generator selectively applies bias voltages at gates of transistors of a stacked driver structure of an IC to prevent the voltage drop across any given transistor of the stacked driver structure from exceeding a predetermined threshold associated with the maximum operating voltage range of the transistors.
