QBLP655R-R

QBLP655R-R is an LED discrete indicator from Avago Technologies which is used in a wide variety of applications. It has a single output, with a maximum forward current of 20mA. The device is based on a standard red-green-blue (RGB) LED, but with a flexible and adjustable brightness level. The device can be used to indicate the status of a specific system or process through a single-color light, or to provide an adjustable spectrum of colors. The device can also be used to monitor temperature, or provide an effective solution for dimming or color control in any illumination application. This article will discuss the applications and working principle of the QBLP655R-R LED discrete indicator.

Applications

The QBLP655R-R LED discrete indicator is used in a variety of applications. It is commonly used in electronics and industrial markets, as it can be used to display the status of a system or process quickly and easily. For example, it can be used to show whether a machine is on or off, or if a system is stable or in the process of a breakdown. It is also widely used in indoor and outdoor lighting applications, as the adjustable brightness level can make it suitable for a variety of lighting needs. Additionally, the indicator can be used to monitor temperatures, or to indicate when a device is out of a specified temperature range.

Working Principle

The working principle of the QBLP655R-R LED discrete indicator is relatively simple. It uses a combination of photodiodes and resistors to create a current source, which is then used to control the brightness of the LED. The device also contains a number of address pins which are used to control the range of brightness, from a minimum value to a maximum value. The device is configured by connecting the appropriate permutation of the address pins, selecting the desired pulse width modulation frequency, and specifying the target voltage.
