DESCRIPTION
The TSOP5P.. series are miniaturized receivers for
Mid range proximity sensor systems. A PIN diode and a
preamplifier are assembled on a lead frame, the epoxy
package acts as an IR filter.
The output pulse width of the TSOP5P.. has an almost linear
relationship to the distance of the emitter or the distance of
an reflecting object. The TSOP5P.. is optimized to suppress
almost all spurious pulses from energy saving fluorescent
lamps.
This component has not been qualified according to
automotive specifications.

IR Receiver Modules for Mid Range
Vishay Semiconductors
Proximity Sensors
The typical application of the TSOP5P38 is a reflective sensor with analog information contained in its output. Such a sensor is
evaluating the time required by the AGC to suppress a quasi continuous signal. The time required to suppress such a signal is
longer when the signal is strong than when the signal is weak, resulting in a pulse length corresponding to the distance of an
object from the sensor. This kind of analog information can be evaluated by a microcontroller. The absolute amount of reflected
light depends much on the environment and is not evaluated. Only sudden changes of the amount of reflected light, and
therefore changes in the pulse width, are evaluated using this application.
Example of a signal pattern:

Separation to avoid
crosstalk by stray light inside
the housing
There should be no common window in front of the emitter
and receiver in order to avoid crosstalk by guided light
through the window.
The logarithmic characteristic of the AGC in the TSOP5P38
results in an almost linear relationship between distance and
pulse width. Ambient light has also some impact to the pulse
width of this kind of sensor, making the pulse shorter.
