Pin Configuration

The TSOP4433 module features a standard pin configuration with three pins: 1. OUT (Output) 2. GND (Ground) 3. VS (Supply Voltage)

Functional Features

The TSOP4433 operates by receiving modulated infrared signals from a remote control and converting them into electrical signals. It has a built-in photo detector, pre-amplifier, and automatic gain control to ensure reliable signal reception even in varying ambient light conditions. The module's active low output signal simplifies integration with microcontrollers and other digital logic circuits.

Advantages and Disadvantages

Advantages

• High sensitivity to infrared signals
• Wide operating voltage range
• Compact and lightweight design
• Low power consumption

Disadvantages

• Limited carrier frequency range
• Susceptible to interference from ambient light sources

Working Principles

When exposed to modulated infrared light, the TSOP4433's photo detector generates a corresponding electrical signal. The pre-amplifier then amplifies and filters the signal, while the automatic gain control ensures consistent performance across varying signal strengths. The module's output pin provides a logic low signal when a valid infrared signal is detected.

Application Field Plans

The TSOP4433 is commonly used in the following application fields: - Remote control systems for televisions, audio equipment, and air conditioners - Industrial automation for infrared-based proximity sensing and object detection - Automotive electronics for infrared remote keyless entry systems
