Default Abusing a 555.

It means he started with wanting to use an NE555 to drive a push pull
MOSFET stage but the MOSFET supply is more than the NE555 Vcc rating.

So, he has to regulate down for the NE555 but now the 'normal' OUT
line, being a totem pole, can't go high enough to turn off the top P
MOSFET.

Well, that's a major DUH - just use an NPN on "out" or "disch" or
whatever,
and let the NPN do the level shifting.

Why do these people insist on making these things so difficult?



That was my point exactly!!!
