Abstract
A system and method is provided for driving an output transistor. The system and method employ a sense control to adjust a drive strength associated with driving the output transistor. The sense control measures an output parameter of the transistor, and adjusts the drive strength based on the measured parameter. The drive strength can be based on a selected driver of a plurality of driver devices with varying drive strengths or selected output devices of a driver of a plurality of output devices of varying drive strengths. The drive strength of the driver devices or output devices can be varied by varying the channel widths of output drive devices selectively coupled to a drive terminal (e.g., gate, base) of the output transistor.
