High voltage switching Posted by Mathijn Bernards in forum: If you switch the load off, so that 1A no longer flows, what happens then? Yes, my password is: How reliable is it?
Your name or email address: Equating complex number interms of the other 6. There will be voltage drop across any solid state switch, which then means it’s just a matter of how much resistance is acceptable. No, i dont think that it is acceptable that the load would turn on and off, then on then datasjeet again. Any suggestion on how to improve it? I would like it such that the circuits used to create the voltage regulation, the current sensing and the temperature sensing remains undamaged ie, the circuit allows the current to flow but the load is cut off.
Interesting enough, if i operated the comparator at 15V, instead of 20V, i got 3V instead of 50mV. This transistor has an on resistance of 5. These are the transistor i am looking at for Tr3: Transistors can fail either short-circuit or open circuit.

If the load current reaches 1A do you want the load to switch off and stay offor do you simply want the load current to be limited to a steady 1A? Vatasheet May Also Like: Oct 31, 3.
Nov 5, Each one of those transistors would receive a signal from the base to turn it on provided that the temperature is less than 40 degree and 1 amp.
At 15A, you can halve that drop, which is miniscule for many applications. Is there a way to do it better? Since little current was flowing, then there would be a diminished pd across the biasing resistor.
This is the diagram that i am using to turn the load on and off.

Nov 1, Input port and input output datasheeet declaration in top module 2. Datasheeh what should happen once the load temperature has dropped below 40C? Nov 6, I am currently thinking of ways that i can improve it.
Do you think these are good results? Similar Threads mosfet configuration doubt to control voltage 7. If the load current reaches 1A, i want the load to switch off and stay off until the current falls below 1A. Sorry about that, I did not show you the entire circuit. I am trying to use transistors as a switch that can be used to remove a load from the circuit at currents greater than 1 amp and datasheef greater than 40 degree celsius.
Discussion in ‘ The Projects Forum ‘ started by c1rcu1tsOct 31, I was hoping for it to be such that the circuit buz33 receive a signal such that if the current is too high, then it would isolate the load and remain off until the current drops below 1A. Next, the load would be placed closer to the high voltage rail.
Choosing IC with EN signal 1. By the way, my reasoning for why 50mV was observed could be because, the gate of the current sensing was soo negative that it inhibited the current from flowing through the 2 FETs.
