And if you don't have this, I posted this circuit example I just made for a delayed power turn on time above. Capacitor is about 5 cents, the transistors are about 6 cents each. If you need it you need it, but power good to the reset line is better.

Or just put a capacitor after the reset line pullup so that it effects delayed turn on during boot.

Oh, neat trick - thanks for sharing!

What is the voltage drop across D1 and Q2? Is that ever an issue?

[neltnerb → Tempest1981]

The drop across D1 can be significant, using a Schottky helps. Usually within the tolerance of the power supply in any case.

But a capacitor on the reset pin is pretty good ;-)
