Hello all,
Searched but didn't find the answer to this-
I have a 555 used as delay-on for a relay. The output is high for ~5 seconds then goes low triggering a pnp darlington and a large relay. The circuit seems to work great except that once in a while the output is stuck low when power is applied. Cycling power solves it, but is there a simple way to nearly guarantee the output is high on power up?
I can post a schematic if needed, but it's just the generic config with Trigger tied to Vcc via 10K and RC of 50K/100uF.
Thanks!
