Pin Description
Figure 6 shows the description of each pin of the standard
SSOP16 package (Shrink Small Outline Package, 16 leads, body
size: 5.3mm x 6.2mmm; see Figure 4).
Pins 7, 15 and 16 are supply pins, pins 5, 13 and 14 are for
internal use and must not be connected.
Pins 1 and 2 are the magnetic field change indicators,
MagINCn and MagDECn (magnetic field strength increase or
decrease through variation of the distance between the magnet
and the device). These outputs can be used to detect the valid
magnetic field range. Furthermore those indicators can also be
used for contact-less push-button functionality.
Pins 3, 4 and 6 are the incremental pulse output pins. The
functionality of these pins can be configured through
programming the one-time programmable (OTP) register.
