Charge injection and drain-based electrical overstress (EOS) protection apparatus, method, and system

An electrical overstress (EOS) protection circuit that at least partially neutralizes or compensates for undershoot and overshoot in first and second signals that are communicated using differential signaling, such as with USB communications. For an undershoot, the EOS protection circuit injects cha...

Zusammenfassung:An electrical overstress (EOS) protection circuit that at least partially neutralizes or compensates for undershoot and overshoot in first and second signals that are communicated using differential signaling, such as with USB communications. For an undershoot, the EOS protection circuit injects charge into pads that receive the first and second signals. For an overshoot, the EOS protection circuit drains charge from the pad that receives the second signal and injects charge into the pad that receives the first signal.
