LEDs are indispensable in modern life, especially when it comes to smartphone, television or car’s display. Not just providing beautiful and convenient display, but also a delicate decoration, making our life lightened. These applications sound very familiar for us now, but in the past, people had to use discrete LEDs for indicating purposes, especially for industrial ones. Using discrete LEDs usually need a special driver to control the lightings, and this is what the RPG1111C-11-TR designed for.

The RPG1111C-11-TR could be classified as a discrete LED indicator. It is designed to drive discrete LEDs on/off, usually used as indicators for industrial control panels. It supports a range of operating voltage between 4.0V and 35V, and wide operating temperature range of -40℃ to +85℃. This great feature makes the RPG1111C-11-TR suitable for even the most extreme applications.

Talking about the structure of this LED indicator, the RPG1111C-11-TR has a very compact structure, integrated with a MOSFET switch, which is used to obtain higher efficiency as compared to a standard LED indicator. This LED indicator also integrates circuitry over-voltage and over-temperature protection. And its high efficiency MOSFET protection supports a very low operating temperature of around -45℃.

The most important thing about this LED indicator is its working principle. It uses a library of standard logic gates, such as NAND, OR, NOR, and XOR, to control the lighting and extinguishing of discrete LEDs. Firstly, the input voltage is passed through the array of logic gates. Then, the output voltage is connected to a MOSFET switch, which acts as a buffer between the logic gates and the LEDs. When the logic output is "HI" or "LOW", the MOSFET switch will open or close, which will result in current flowing through the LEDs. When the LEDs lit up, the logic gates will be reversed, and the circuit will be ready to light up once again.

In conclusion, RPG1111C-11-TR is a discrete LED indicator with great performance and versatile functions. Not only it supports a wide range of operating voltage, but also integrateds circuitry over-voltage and over-temperature protection. It mainly uses a library of logic gates to control the lighting and extinguishing of discrete LEDs. It is a great choice for controlling industrial control panels and applications in harsh environment.
