TSOP32338 Application Field and Working Principle

Optical Sensors are devices that detect light and convert it into electric signals for application in different fields. Photo Detectors are one of the key components in optical sensing, in which they detect modulated or unmodulated eletromagnetic radiation from visible to near infrared spectrum. Remote Receiver, part of the Photo Detectors, receive infrared (IR)signals transmitted from other sources such as remott controllers to initiate different actions.The TSOP32338 is one of the Remote Receivers from Vishay Semiconductors. It is of small outline package type with leadless leadframes (LLP). It features high sensitivity, wide supply voltage range, low power consumption and extremely low noise. It has a fast response time of 20µs. It is used as a close-range IR receiver for embedded applications.

TSOP32338 Working Principle

In the most basic sense TSOP32338 works by converting incoming IR signal into an electrical signal which is processed in embedded applications to initiate different actions. They have a filters built-in that allow them to filter out unwanted information in a signal to remain with only the communication.The main components of TSOP32338s are photosensors, integrated circuit processing part, signal output terminals, and a filter element, which are respectively housed in a plastic case with copper strip contacting points arranged on the outside of it.

Application Fields

The TSOP32338 is widely used in computer peripherals, smart TVs, home appliances, mobile phone, audio-visual equipment, LED lighting systems, air conditioners, and alarm systems as a close-range IR receiver. It acts as a transceiver of controlling signals with associated embedded devices. This allows the users to interact with their devices wirelessly. Also, since TSOP32338 is can be integrated into smaller packages, it is used in the automotive industry where it serves as an IR detector in headlights for adaptive high beam, parking assist systems and night vision systems.

Conclusion

The TSOP32338 is a Remote Receiver from Vishay Semiconductors which features high sensitivity, wide supply voltage range, low power consumption and extremely low noise. It has a fast response time of 20µs. It has integrated filters to filter out unwanted information from the signals. The TSOP32338 is used as a close-range IR receiver in various fields such as computer peripherals, automotive industry, home appliances, audio-visual equipment, LED lighting systems, air conditioners, and alarm systems.
