Optical Sensors have a range of applications within industries such as automotive, electronics and communications, as well as medical and environmental applications. Photo Detectors can be used to detect light and convert it into electrical signals. Remote receivers are an important part of the receiver elements of photo detectors and are used to receive light from a remote light source. The TSOP37356TT1 is an example of a remote receiver and this article will discuss its application field and working principle.

The TSOP37356TT1 is a miniature size remote control receiver IC which has a built-in photo detector. It is a high speed, ultra-low power, low voltage 4-pin CMOS device which has been designed to provide exceptional sensitivity for remote control applications. The device works on a 5V supply voltage and its photo detector is designed to detect infrared signals in the wavelength range of 940 – 950 nm. It is also able to detect signals from a wide range of distances, as far as 25 feet away, depending on the type of LED used. The device is highly sensitive, making it ideal for use in various remote control applications such as home automation, TV remote control, multi-function remote controllers, security systems, etc.

The working principle of the TSOP37356TT1 is based on the phototransistor effect. When the device receives infrared light from the remote source, the photodetector inside converts the light energy into electrical energy. This electrical energy is then used to switch the output transistor, which is connected to ground. When the current switched is high enough, it will pull the output pin of the IC low, which is then used to drive the processor or system.

The TSOP37356TT1 is highly reliable due to its low current consumption and low voltage operation, making it ideal for battery operated systems. The device also has a wide operating temperature range from -25°C to 70°C, allowing it to be used in environments where extreme temperatures are present. Additionally, it has excellent immunity to ambient light making it suitable for outdoor applications. It is also ESD protected, in order to protect against static electricity.

In conclusion, the TSOP37356TT1 is a compact and highly reliable 4-pin remote control receiver IC which is designed for low power and low voltage applications. It utilizes the phototransistor effect to detect low level infrared signals from a remote source and can detect signals from a wide range of distances, depending on the LED type used. It has excellent immunity to ambient light and is designed for battery operated systems, making it ideal for various home automation, TV remote control, multi-function remote controllers, security systems, etc. applications.
