TLMB3104-GS08 LED Indication - Discrete

The TLMB3104-GS08 is an innovative device from the variety of optoelectronic devices from Texas Instruments which combines a chip scale package with a long life gallium arsenide infrared LED and a sensitive integrated photodetector in an exceedingly compact and reliable package. This device offers a range of potential applications, most significantly in the field of LED indication, where size and low power requirements can often be a challenge to designers. By combining the LED emitter and detector within the same package, the TLMB3104-GS08 significantly reduce the size, complexity and soldering involved in implementing a discrete LED indicator solution.

Applications

The TLMB3104-GS08 is a highly flexible device with wide ranging application possibilities. Examples include:

• Mobile device indicators. This device can be an ideal replacement for the traditional discrete LED indicator on small portable electronic devices, significantly reducing the power and physical space requirements compared to other products - small size is key in the mobile market and the TLMB3104-GS08 helps create a sleeker finished product.
• In-line indicator. On any automated process or manufacturing line, where indicators for input or output signals are required, the TLMB3104-GS08 acts as a true plug and play device. The small size, LED integration, and ease of connection make this device a suitable choice for any in-line indicator.
• Barcode readers. The integrated LED and detector are ideal for use in barcode scanners and other optical data input devices.

Working Principle

The TLMB3104-GS08 is an integrated device which contains both the LED emitter and photodetector within the same package. The LED emitter is a long-wavelength Gallium Arsenide infrared LED which is powered by an external source. The LED produces light which is detected by a sensitive integrated photodetector which then transmits a signal to the output pin of the device. This output pin is then connected to a microcontroller or other input device where the signal is processed and a series of actions are triggered.

Conclusion

The TLMB3104-GS08 is an innovative device which provides designers with significant improvements in terms of size and power requirements compared to other discrete LED indication solutions. This device is suitable for use in a range of applications including mobile device indicators, in-line indicators, and barcode readers. The device integrates an LED emitter and detector within the same package, which simplifies wiring and increases the device’s sensitivity. This device is sure to be a valuable addition to any designer’s toolbox.
