Abstract:
1. An integrated electronic circuit, comprising: a plurality of integrated semiconductor and other electronic devices for driving power switch transistors with PN-junction control inputs; a first drive output circuit that provides as a first drive signal either a constant current or a constant voltage signal; a second drive output circuit that provides a second drive signal, comprised of a change in voltage and flow of charge, each of magnitude substantially greater than corresponding electrical signals provided by the first drive output circuit, that is coupled into the first drive signal; a first power supply input; a second power supply input, substantially lower in voltage value than the voltage of the first power supply input; a power supply selection circuit that selects either, or both, of the first and the second power supply inputs; and a common electronic package or semiconductor substrate that integrates the first drive circuit, the second drive circuit, the power supply selection circuit, and associated other electronic circuits and devices.
