Data Sheet – Alignment Mode
www.austriamicrosystems.com
Revision 1.80
19 – 36
14 Alignment Mode
The alignment mode simplifies centering the magnet over the chip to gain maximum accuracy and XY-alignment
tolerance.
This electrical centering method allows a wider XY-alignment tolerance (0.485mm radius) than mechanical centering
(0.25mm radius) as it eliminates the placement tolerance of the die within the IC package (+/- 0.235mm).
Alignment mode can be enabled with the falling edge of CSn while PROG = logic high (Figure 15). The Data bits D9-D0
of the SSI change to a 10-bit displacement amplitude output. A high value indicates large X or Y displacement, but also
higher absolute magnetic field strength. The magnet is properly aligned, when the difference between highest and lowest
value over one full turn is at a minimum.
Under normal conditions, a properly aligned magnet will result in a reading of less than 32 over a full turn.
Stronger magnets or short gaps between magnet and IC may show values larger than 32. These magnets are still
properly aligned as long as the difference between highest and lowest value over one full turn is at a minimum.
The MagInc and MagDec indicators will be = 1 when the alignment mode reading is < 32. At the same time, hardware pin
MagRngn (#1) will be pulled to VSS.
The Alignment mode can be reset to normal operation mode by a power-on-reset (cycle power supply) or by a falling
edge of CSn with PROG=low (see Figure 16).
