BJT Output Stage

[cyntrex]

Hello.

I need some help with this little BJT circuit. Its meant to switch the load at the Q3 collector on and off. Q1 &Q1 are controlled by 5V. Q1 should be able to limit the voltage at Q3 base, or in the other case, get it up to 24V, so that there is no voltage at Q3 base-emitter. Would this circuit work like this and do i just have to adjust the resistors, or am i completely off guard here? I'm kinda stuck here, so any help is appreciated.

Kind regards

Hi.

Looks like some part of your schematic is missing.

You're in great risk of making a shortcut through Q2 and Q3.

The rest of the schematic is just my logic circuit, which also assures, that Q1 and Q2 will never be active at the same time. So no shorts there.

That circuit will blow up. Good luck.

Not if the op can ensure that Q1 and Q2 are never "On" at the same time.

What is the load being switched. Also, what is your question? Does the circuit not work as intended? If so, in what way?
