Controller for a switch and method of operating the same
First Claim
1. A controller for a switch configured to measure a voltage of a control terminal of said switch and select a first mode of operation if said voltage of said control terminal is greater than a threshold voltage, and a second mode of operation if said voltage of said control terminal is less than said threshold voltage, wherein said first mode of operation signifies that said switch is a field-effect transistor and said second mode of operation signifies that said switch is a bipolar transistor.
