Hi,
I have a circuit that runs off a 5VDC regulator. I need to drive 2 relays, and the ones I have are 6Vdc, but ofcause they switch fine at lower voltage.
The problem is, to switch the relay I have a transistor, and then a diode to prevent back current, after the transistor and diode I am left with 3.8V which is very close to the limit of what the relay will accept, so its not that reliable.
Is there a way to limit that loss, or do I have to run at a higher voltage to start with ?
