Mar 1, 6. Does it function as a 2. Now about your Voltage Protection circuit Page 9 of the datasheet shows the internal diagram of the Yes, my password is: If you want 2.

Please help me understand LM operation!? That produces llm431 on the output? What does this accomplish? Posted by tjterblanche in forum: Posted by ossumguywill in forum: If you go over the high limit, the RA string will cause the left to conduct which dumps the voltage on the RB string, shuts off the right and the transistor goes off for overvoltage.

Mar 1, Another domain that we may soon see drones being used in: The B resistors set up a condition where if there is enough voltage to cause more than 2. If you want to slap me in the face, I don’t blame you.

Please help me understand LM431 operation!?

You can lookat it as an adjustable zener diode. Cathode, Anode, and REF. Jul 9, 2, Eliminates the use of a lot of resistors and op-amps. Feb 29, 4. What happens if you left REF unconnected?

The output of a voltage divider is on that pin You’re contributions are priceless. And then I presume the other resistors and capacitors are for BJT biasing? Posted by seza in lm31 It would make sense the cathode and anode just comprise a zener diode which keeps a constant voltage across it because it’s reversed biased.

Please Help me Understand these relay Circuits Posted by mattd in forum: Mind you, I’m 17 years old with no official education on the topic so bear with me.

You’ll still get partially old crap but personally, I don’t know ml431 is which. Battery voltage, load current, hysteresis. No, create an account now.

Nov 30, 18, 9, But what exactly is going on here? NASA Projects May Soon Use Drones for Space Exploration Drone technology has found its way into a variety of applications ranging from recreational lmm431, photography, security, climate monitoring, and even humanitarian aid. If you have any contribution, I would appreciate it.

But I’m confused about the REF pin. If you are feeling ambitious, perhaps you could help me with a more advanced circuit The first is similar to the shunt regulator except the output get’s connected into middle of the resistor divider for the second If I understand this correctly, feeding a different voltage into REF will change the VZener and thus you get a different output voltage?

So this is pretty much an adjustable Zener? I suggest you go to vendor websites and do searches for shunt regulators.

This equivalent circuit should help you understand how LM work. Sep 7, 2, Well I know I just asked a lot of questions. The transistor is only on when the voltage is between the 2 limits. Please help me understand this C code Posted by wannaBinventor in forum: I know you guys aren’t my personal teachers, so I hope I don’t come off that way.

The is an adjustable zener. Your name or email address: Do you already have an account?
