i have implemented this circuit using IRF9540 Mosfet that is P-channel. when i connect a load of 6.8 ohm it gives current almost 3 A. but current value is constantly decreasing with time .. i think its becoz of MOSFET heating..can u suggest me any other P-channel MOSFET,,
Thanks

Thanks for the help.. will ask you some more things when needed.. one more thing can u please give me the working link of spice software ... cracked version... i want it for my simulations..
Thanks again ..
:smile:
Thanks.
i have simulated this thing .. you use R4 of 4.3 K and Rsc 0.15 ohm. i have calculated the values of these resistors using the equations. Rsc comes out to be 0.14 ohm and R4 is 10k. i simulated it at load values of 0.1 to 10 ohms. at 4.9 ohm it reaches peak value of 5.2 amp while at o...
Thanks for the help.. i have implemented the same circuit and it works fine but the problem is that in my case vin - vout is zero or not? My input and output are almost same that is 28 volts. also i want to know that can it fold back current from 5Amp to 3 usi8ng the same configuration or i have...
i have tried this circuit but it doesn't work .. m a little confused about fold back.. the equation 1 given in the reference says (Vin -Vout) . in my case they are same almost. if u have any circuit simulation kindly give me that ..
Thanks ..
i want to know that in my case i connect my load in parallel with the capacitor? the simulation results are missing in the attached file .. i try to simulate this but it doesn't satisfy me.. also i want to tell u that the part numbers of transistors and Mosfet's are interchanged.. kindly help me...
basically i want to do is that i have a 28 volts bus and other systems that are acting as load. now i want to design a system that fold-back the current after it reaches a limit of 5 Ampere. i dnt want the other systems to be shutdown just to foldback the current to a suitable value that is not...
can u plz tell me the name of this book and the author of the book . i want to design fold back current limiter circuit up to a range of 5 Ampere.. Thanks in advance
THNx for replying but i dnt knw any thing about this sensor i have read all data sheet but i cannot find any thing..CAn u tell me how to calibrate it and if u have any idea about its coding then plz tell me ....
