I have a dual coil relay. The coils are rated for 12v. The coils set (or reset) at 6v, and require a pulse of between 15 and 100 milliseconds.

The relay is TE Connectivity, part # V23130-C2021-A412.

I am trying to make a driver that will pulse the set coil when the driver's input is high (12v) and then pulse the reset coil when the driver's input goes low (0v).

I have found the following circuit that would work for a coil that accepts continuous current but it does not give a pulse:

(Note: the diodes will not be required because my relay has internal flyback diodes).

Simply adding a capacitor between the voltage supply and the coils would give a pulse but there would be no way for it to discharge.

I would also consider some kind of IC if that is required but would like to avoid an IC.

I would be grateful for any suggestions.
