DESCRIPTION
The TSSP77P38 is a compact infrared detector module for
proximity sensing application. It receives 38 kHz modulated
signals and has a peak sensitivity of 940 nm.
The length of the detector’s output pulse varies in proportion
to the amount of light reflected from the object being
detected.
FEATURES
• Up to 2 m for proximity sensing
• Very low supply current
• Photo detector and preamplifier in one package
• Shielding against EMI
• Supply voltage: 2.5 V to 5.5 V
• Visible light is suppressed by IR filter
• Capable of side or top view
• Insensitive to supply voltage ripple and noise
• Two lenses for high sensitivity and wide
receiving angle
• 940 nm peak wavelength
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Object approach detection for activation of displays and
user consoles, signaling of alarms, etc.
• Simple gesture controls
• Differentiation of car arrival, static, car departure in
parking lots
• Reflective sensors for toilet flush
• Navigational sensor for robotics

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 TSSP77P38
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.

ESD PRECAUTION
Proper storage and handling procedures should be followed
to prevent ESD damage to the devices especially when they
are removed from the antistatic shielding bag. Electrostatic
sensitive devices warning labels are on the packaging.
