Hey Guys,
I need to turn ON 12v load (up to 2A current) using a microcontroller. So when microcontroller port pin is at "HIGH" (5v), the 12v load should be turned ON. Like a switch, I thought of using NPN and PNP -transistor combination, but I have 12 output loads to be controlled using microcontroller, so 12x2 = 24 transistors is not feasible. As i have to make the circuit very compact like a usb drive. So any Suggestions, pls help....Any ICs which can do the job??
