AS5171 − Register Description

Customer ID

A specific identifier chosen by the user can be stored in the

non-volatile memory. This identifier consists of 4 bytes and can

be stored in the locations CUSTID0, CUSTID1, CUSTID2, and

CUSTID3.

Output Linear Transfer Function

A linear transfer function controls the state of the output in

response to the absolute orientation of the external magnet.

The parameters which control this function are shown in

Figure 21.

To calculate this settings into the corresponding sensor

settings, ams provides a programming tool, specific DLL or the

complete source code. For more information, please contact

ams.

Figure 21:

Transfer Function Control Parameters

As shown in the Figure 22, the parameters T1, T2, OT1, and OT2

define the input-to-output linear transfer function. The

dedicated programmer for the AS5171 uses the parameters

from Figure 21 to generate the corresponding settings CLMPL,

CLMPH, PPOFFSET, PPGAIN and BP (see Figure 22).

The clamping level parameters CLMPL and CLMPH define the

absolute minimum and maximum level of the output. Both

clamping levels can be set with the 12 LSBs out of the 12-bit

output resolution. CLMPL and CLMPH must always be set

outside of the lower and upper diagnostic failure band defined

by the output broken wire voltage (see Figure 22: BGPD and

BVPU).
