Abstract
Circuits and methods for suppression of negative transient voltage may be implemented in systems that combine high-speed data, audio, and charging at a plug. The circuits and methods for suppression of the negative transient voltage may include a first diode and transistor coupled in series between a pin and ground, where the transistor is controlled by an output of a voltage comparator that is also coupled to the first pin. A negative transient voltage event may cause the comparator to activate the transistor to sink a current through the diode.
