Hi,
I am in need of a circuit to do the following scenario.
I have a coil in my circuit. It has to be operated in 5V for 60 seconds. Then it must be operated in 1.5V for 90 seconds. This must be happening continuously. I have a microcontroller in my circuit. So the timing issuce can be solved with the controller. But the problem is i need 1.5V and switching between the voltages. If any one has and idea please share with me. It shouldn't be a complicated circuit. Since my PCB is almost complete and i am not in a position to add more components.
Thanks
Siva.
