DESCRIPTION
The IC is an optical sensor which provides a non-mechanical de-
tection of movements. The EEPROM allows a free configuration of
the sensor-structure and the detection algorithms.
The sensor measures the optical reflections of an object on a cov-
er above the sensor using a system so called HALIOS® (High Ambi-
ent Light Independent Optical System). HALIOS® is high efficient
suppressing ambient light and also has an inherent self calibra-
tion to eliminate disturbances caused by housing reflections such
as scratches.
The infrared emitting diodes (IRED, signal diodes) and the photo-
diode are placed on a PCB in a required formation. The ability to
detect the motion of an object on the surface depends on chang-
es in the optical path of the reflected signal, changing the relative
light intensity of LED pairs.
With 4k of EEPROM the customer has enough memory space for
even complex applications and an easy to use posibility to protect
his know how even in a ASSP.
For automotive, industrial and pc applications a version 909.03
with integrated IR diodes and photodiode is available in an ASIC^plus
package.
