RE46C105E14F Application Field and Working Principle

RE46C105E14F is a type of tiny, integrated infrared receiver from ROHM Semiconductor, widely used in TV remote control, car remote control, automotive, telecommunication systems, and other related applications. It is designed to detect infrared emitted from an infrared LED, convert it into an analog voltage, and output the voltage for further processing. It has excellent infrared sensitivity in a wide range of operating temperature, and is compatible with both digital and analog circuits.

Application Field

RE46C105E14F infrared receiver is widely used in TV remote control, car remote control, automotive, and telecommunication systems. It plays an important role in receiving far-field, infrared signals without needing an additional receiver module. It offers excellent noise immunity by filtering the pulses, resulting in the reliable detection of up to 8-bit-resolution infrared communications.In the automotive market, RE46C105E14F infrared receiver is used in rearview-mirror dimmers and manual shift levers as a single-chip solution. It enables the operation of a car’s power-locks, power-windows, anti-lock brakes, and entertainment systems with reliable infrared transmission.In the telecommunications market, the device can be used as a dialer for smartphones and mobile phones. It makes the dialling of call numbers more convenient and user-friendly, allowing the user to dial the numbers from the phone by pressing the buttons of the infrared remote controller.

Working Principle

RE46C105E14F infrared receiver is a widely used type of infrared remote control device. It works by receiving an infrared signal from an infrared LED, converting it into an analog voltage, and outputting the voltage for further processing.The device is compatible with a wide range of operatingVolts and has an excellent performance in terms of sensitivity and noise tolerance in a wide range of operating temperatures. The device’s highly sensitive GaAs (Gallium Arsenide) PIN photodiode converts the pulses into 8-bit resolution pulses. These pulses are then filtered by the unique noise-rejection circuitry, which helps the receiver detect reliable infrared communications between digital and analog components.The voltage obtained from the diode is amplified by the internal amplifier and is compared to an internal reference voltage. This comparison yields an analog voltage representing the pulse width, which is then outputted. The integrated analog output module also provides an adjustable output voltage range and a wide operating temperature range.

Conclusion

RE46C105E14F infrared receiver is a widely used device for various applications, such as TV remote control, car remote control, telecommunication systems and automotive. It is designed to detect infrared radiation emitted from infrared LEDs and convert it into an analog voltage for further processing. The device offers excellent noise immunity, which helps ensure reliable detection of 8-bit resolution infrared communications. The device also features a wide range of operating volts and wide operating temperature range, making it highly versatile.
