The TSOP 37556TT1 (hereon referred to as TSOP) is a remote receiver dedicated to infrared systems. It should be classified under Optical Sensors - Photo Detectors - Remote Receiver and is the ideal component for designing wireless remote control systems. This article explains the working principle and application field of the TSOP in more detail.

Working Principle

The TSOP 37556TT1 is extremely sensitive and is suitable for a variety of applications. The device consists of a phototransistor, resistors, common-emitter amplifier and output driver. When the infrared source is activated, the TSOP acts as an active component which amplifies the weak infrared signal through the integrated circuitry, before connecting it to the user\'s appliance.

The amplifier draws its current from the power supply. The phototransistor draws very little current and activates the amplifier. The signal is then amplified by a common-emitter amplifier within the device. After passing through the amplifier circuit, it is fed into an output driver, which helps to protect the device from power spikes and overvoltages.

The output driver then filters and amplifies the signal before it is sent to the user\'s appliance. The TSOP\'s integrated circuitry ensures that the signal is transmitted accurately and reliably. This allows the user to control their appliance from a distance of up to 20 meters away.

Applications

The TSOP 37556TT1 is suitable for a variety of infrared applications that require longer range reception. It is commonly used in remote control systems and is especially suitable for digital television and satellite receivers, garage door openers, remote controlled toys and lighting systems.

The device is also used in robots, where it is used as a photodiode to detect objects. By using the TSOP in combination with a microcontroller, robots can sense incoming signals from infrared sources and adjust their behavior accordingly. This allows the robot to sense its environment and navigate obstacles.

In addition, the TSOP 37556TT1 is used in combination with an infrared LED to detect motion. By using an infrared LED and TSOP sensor, an electronic system can be designed to detect movement or the presence of people within a certain distance. This is commonly used in security systems, such as door entry systems, where it can be used to detect intruders.

Conclusion

The TSOP 37556TT1 is a remote receiver dedicated to infrared systems and should be classified under Optical Sensors - Photo Detectors - Remote Receiver. The device consists of a phototransistor, amplifier, output driver and resistors, making it ideal for designing wireless remote control systems. The TSOP is suitable for a variety of applications, ranging from digital television and satellite receivers, to door entry systems and robots.
