I am trying to use transistors as a switch that can be used to remove a load from the circuit at currents greater than 1 amp and temperatures greater than 40 degree celsius. My original idea was to use the transistors to create an and gate by connecting two transistors by joining the emitter of an NPN transistor to the collector of another NPN transistor. Next, the load would be placed closer to the high voltage rail. Basically like this diagram attached but not exactly. Each one of those transistors would receive a signal from the base to turn it on provided that the temperature is less than 40 degree and 1 amp. The voltage rail would be a regulated 9V instead of a 6V. The problem being formed is that i want the pd across the load to be 9V, however the transistors would inhibit this.
I am asking for possible solutions or a direction where i can read to obtain knowledge to solve this.
Thank You
~ yes i am new to using transistors as switching circuits.
