Abstract
An integrated circuit is provided. The integrated circuit includes a central processing unit built to process data and an output pin of the integrated circuit to provide processed data at the output pin to an external device connected to the output pin and a driver for the output pin with an output MOSFET of the driver connected to the output pin to provide the processed data with the power specified for the output pin. The driver includes a dynamic driver stage built to switch the output MOSFET between its conductive and non-conductive condition and a static driver stage built to maintain the condition of the output MOSFET until the dynamic driver stage switches the condition.
