Are there any solid state options available for a simple relay for a 9v battery backup?
Power to the device will be DC +5V. If this voltage drops below a specified level, say 2.5V, a relay should switch to a 9V battery backup (with a voltage regulator, of course).
I've done some searching but I'm having trouble coming up with something like a part number or datasheet.
Thanks!
