Optical Sensors - Photo Detectors - Remote Receiver

TSOP75440WTT is a discrete infrared (IR) remote control receiver that operates at a carrier frequency of 38 kHz. It is typically used in home entertainment applications to receive commands from a conventional IR remote control. It is packaged in a miniature surface-mount package so it can be integrated into space-limited designs.

Application field

The TSOP75440WTT is designed for applications that require low cost and wide range of reception. It is suitable for use in home theaters, DVD recording equipment, point-of-sale terminals, access control systems and security systems. It has the ability to receive standard Infrared Remote Control (IRC) protocol from up to 5m or 16.4ft away. It\'s widerange of sensing angle makes it a perfect choice for many environments as well.

Working principle

The TSOP75440WTT uses a dedicated demodulator integrated circuit, which encodes data received from the low-power, narrow-band infrared (IR) source into a serial 10-bit data stream. It has an operating frequency range of 38 kHz with a wide acceptance angle and a high reception sensitivity, allowing it to be used in a variety of applications.

The TSOP75440WTT has a built-in infrared filter that ensures that only signals sent from IR transmitters within its frequency range are decoded correctly. It also has a built-in synchronization circuit that ensures the data is only decoded when the carrier frequency of the signal is exactly 38 kHz. The component is mounted on a compact 7 pin SOP size package, making it ideal for applications where space is a premium.

The receiver will detect an incoming signal and convert it into a digital data stream. The data is then outputted via the active low pin, which sends the data to an external microcontroller or to a digital interface. The device also has a dedicated pin that is used to indicate if an active signal is present or not. This active low pin is pulled low when the receiver is not receiving an active signal and pulled high when the receiver receives a signal.

The TSOP75440WTT is designed to operate from a wide supply voltage of 2.4V to 6V and draw a maximum current of 5mA, making it an ideal choice for a wide range of applications. Also, the component is designed to operate in temperatures ranging from -25 °C to 85 °C for reliable performance in a wide range of temperatures.

In conclusion, the TSOP75440WTT is an ideal choice for applications that require a wide acceptance angle, low cost, and high reception sensitivity. With features such as built-in infrared filter, synchronization circuit, and operating in a wide range of supply voltage, it is an ideal choice for a variety of applications.
