Datasheeets & Application Notes

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. The supply is a DC by the way. The load would buz30 2, 5 ohm 5 W resistors in series. How reliable is it?

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 temperatures greater than 40 degree celsius. If the load current reaches 1A, i want the load to switch off and stay off dqtasheet the current falls below 1A. At 15A, you can halve that drop, which is miniscule for many applications.

My original idea was to use the transistors to create an and gate by connecting two transistors by joining the emitter of an NPN transistor to the collector of another NPN transistor. I was hoping for it to be such that the circuit would 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. My apologies if i am not using the correct terminology. This is the entire circuit.


Must either independently or both simultaneously conditions apply to cause load removal? Nov 1, 9. Criticism with reason is very much welcome Thanks again. Thank you very much for your help. Do you already have an account? The voltage rail would be a regulated 9V instead of a 6V. Oct 31, 3. Your name or email address: Not necessarily limiting the 1A but it is a good suggestion thank you. Discussion in ‘ The Projects Forum ‘ started by c1rcu1tsOct 31, However i am encountering some problems.

Oct 31, 4. I shall clarify whatever you want. PIC16f configuration datzsheet doubt 9. The time now is I checked the data sheet but it is of no use. What applications does angular detection offer? AF modulator in Transmitter what is the A?

What would happen if the difference between the two terminals dataheet 0V? Dec 242: If you absolutely require a full 9V drop, and you cannot increase your regulated daatsheet, then you buz30 have to use a relay, or similar mechanical switch that will not cause a significant voltage drop. Distorted Sine output from Transformer 8. Any suggestion on how datashdet improve it?

This is the diagram that i am using to turn the load on and datashert.

How does it work? Yes, my password is: Sep 17, 8, 2, If any of these conditions are not met, then the load is disconnected. Heat sinks, Part 2: It is easy to arrange to switch datassheet the load when the current reaches 1A, then keep it off indefinitely.


Is there a way to ensure that the load remains off intead of on and off again, and again? Quote of the day. High voltage switching Posted by Mathijn Bernards in forum: If this is correct, or you agree, can you give me an idea on what kinda of transistor i should choose and why.

What has a 40C temperature?

I am going to try and use a lower potential than ground for Vee for the comparator bbuz330 see if the problem can be fixed for this circuit, i am using the BUZ n-channel mosfet and the MCP comparator ic. There are a number of problems with your post 13 circuit.

And what should happen once the load temperature has dropped below 40C? Just a thought, maybe Tr3 could be a low Rds on logic-level N-MOSFET, and to minimise the Rds, you could use an op- amp which saturates the voltage signal, going into the gate of the mosfet, to increase Vgs. When would you choose a relay over a transistor for switching? The problem being formed is that i want the pd across the load to be 9V, however the transistors would inhibit this.
