ABSTRACT:
In the circuitry of this invention, a pre-drive controls the output voltage from the driver to the load. The drive includes a resistor and an output transistor. This circuitry lowers the heat dissipation of the transistor of the output driver. Variable voltage input may supply power to the pre-driver.
