Abstract

Disclosed are methods and corresponding systems to detect and prevent and/or eliminate overload conditions for a transistor. According to an embodiment, a method includes providing an input signal to a base terminal of a transistor for a first amount of time, determining if an overload condition exists at the transistor, disabling the transistor for a second amount of time when the overload condition exists at the transistor, and providing the communication signal to the base terminal upon expiration of the second amount of time. Additional overload conditions can be checked upon expiration of the second amount of time as well.
