AMS-AS5600 Contactless Potentiometer

Message:

Hello, I am working on a project that requires position feedback. I chose the AS5600 for this task. To start with I used the circuit that was provided in the manual (option B) which consists of a connector, 2 capacitors and the 5600 IC. For some reason I can’t get the unit working in the analog mode. I get 5v on the output at all times regardless of magnet position. I got this value before the magnet was placed anywhere near the IC. I’ve moved the magnet away from the IC with same results. Important note I should mention is that the magnet is a lot stronger then what was specified in the data sheet.

Magnet spec:

Dimensions: 1/4" od x 1/8" id x 1/4" thick
Material: NdFeB, Grade N42
Plating/Coating: Ni-Cu-Ni (Nickel)
Magnetization Direction: Diametrical
Surface Field: 5299 Gauss
Brmax: 13,200 Gauss
BHmax: 42 MGOe

Is this simply a problem of too much magnet or something else I’m missing?

Regards

Hello @ROVguy,
Sorry for the delay in getting in touch. Since I have not worked with this chip I have forwarded your question to my Engineer and Product Manager who work with AMS to see if we can get an answer. As soon as I hear back i will update this post.
Thank you
