An electronic system for an electric drive mobile machine includes at least one transistor that emits heat, a pressure detector that generates a pressure signal, a temperature detector providing a first temperature signal indicative of the detected first temperature and a second temperature of or substantially adjacent to the transistor, and a controller configured to determine a temperature protection set point based upon the first temperature signal and the pressure signal and execute a control strategy for thermally protecting the transistor when the first temperature signal indicates that the first temperature reaches the temperature protection set point.
