Hall-effect sensor based circuit design

[AEW]

Good afternoon,

Does anybody know a tool or a software to design a hall-effect sensor (A132X family from Allegro MicroSystems) based circuit in order to measure magnetic flux leakage?

Thank you,
Issam

Have you talked to Allegro?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

i recently used this or similar hall sensor... I just used the circuit shown as example in their data sheet. What is wrong with that? Why do you feel you need some tool or software product to make a hall sensor work when the data sheet shows how to hook it up and use it?

There are simply alternatives:

OK, but how to simulate the circuit and see the different outputs?

As described in the OP, you would need some sort of magnetic FEA program to correctly model the problem

Exactly, I am looking for a FEA program that could easily be obtained.
So any suggestions?
Thank you.

What you are asking for per your OP does not exist. There are no commercial programs that mate FEA with circuit design.

> What "design" do you think there is to do?


Why not just buy a magnetometer and try it, or even just use your smartphone?

First, Some of that series is now obsolete.

Second, that device has THREE pins: +5Vdc, common, and output.

Third, voltage output is proportional to the applied magnetic field. The A132X family has a quiescent output voltage that is 50% of the supply voltage and output sensitivity options of 2.5 mV/G, 3.125 mV/G, and 5m V/G.

So Fourth, measure the output voltage and you have measured the magnetic flux.

Exactly WHAT do you need to design?? I don't see how a hall could be more plug and play and require ZERO design?
