Abstract
A driver circuit has pre-driver and transistor pairs coupled in parallel paths with different delays in different paths allowing the driver to automatically adjust to load conditions, providing a moderate driver with low output ringing for low capacitive loads, while the added delay in the different paths is negligible when driving heavy capacitive loads. The driver circuit automatically scales drive strength of the output driver during switching transients to the load capacitance, providing a good trade-off between fast transient and low output ringing for a variety of different capacitive loads.
