Ok, here you go madmike. I think this will be exactly what you want. Check the following link out.

Complete schematic.
I am dealing with the same issue and I was shocked to see this post. I am using MAX202CDR to read RS232 from a 0-5V source. "Block diagram" would look like: Source goes to MAX chip then to PC via HeadPhone Jack. The headphone jack converts to DB9. Anyways, with RS232 fading away, I want to...
I agree that you have a point. But, I also think you forgot the question.
"Why are these in parallel?"
The answer:
They're not...they're considered to be in series.
Errr...what? This is a basic question asked in a circuits class for the soul purpose of learning about the functionality of the BJT. You find the voltage for the Base region and in order to do that...voltage divider. Of course...if this circuit was a piece of a much larger one...i would...
My Circuits I class covered the basics of resistors, thevenin equivalence, op amps, and I believe we touched on the time domain of RLC circuits. Circuits II focused more on your complex equations, filters, and bode plots. I think we touched on transformers as well. Electronics (which was...
Hey all,
This newb needs help understanding the posted circuit. Real quick, I'm going to post what I understand from left to right.
R53 and R62 = Voltage Divider
D2 = Clamping Diode (Clamping to 3.3V)
R45 = R1 in basic (R2/R1)Vin = Vout op amp formula
This is where I get stuck.
Let's...
You need to follow the nodes. Always best to redraw the circuit in a manner that is "more obvious" to you. And like I said, this is best done by following the nodes. KVL should give you the answer. However, make sure you've drawn the circuit correctly.
Yep, sorry, probably should have done that in the first place.

I am thinking the term is bypass capacitor. But still, an explanation would be great.
Hello,
I feel like I know the answer to my question, I am just having a lot of difficulty putting it into words. The questions is the following:
I have a BLDC driver chip that has a pinout called PBAT and a pinout called VCC. The PBAT is tied to 12V and the VCC is tied to a 2.2uF cap...
Your protection may actually be more than necessary for our applications. But 30V for a second I would say is bare minimum...least that is what first design is capable of.
@Berkeman, you're right the second is ridiculous. But the first, I got a decent explanation as to its purpose and it is protecting transients after dsp. I believe you were referring to right before comm w/ PC.
@DragonPetter, I would greatly appreciate that schematic if you are willing.
Thank you for quick response. The second is meant to protect from any shorts...which I believe is really the only main concern. But the first, I have no idea what it is doing. Why is second wrong?
