The light output of LEDs can be controlled by varying the amount of current flowing through the LED( within defined limits) or by turning the LED on and off via pulse width modulation( PWM). LED drivers like the ALD6 series can provide “ dimming ” by both of these popular methods. The drawing above shows the two light-dimming styles included in the ALD6 LED driver. It's permitted to use a combination of both of these methods simultaneously in  Opto Electronics . The “ Rbr ” is an external variable 10kohm resistor input. By varying this potentiometer from 1k to 10k ohms, analog dimming control is achieved. In this case, the maximum LED brightness occurs when the pot is set to 10k ohms. This same input can operate with variable analog voltage ranging from1.6 to3.8- volts. In some applications this input can be connected to a temperature sensing device which could reduce the current inflow through the LEDs as the temperature rises, providing a means for temperature compensation. The ...

A microcontroller is an integrated circuit( IC) device used for controlling other portions of an electronic system, generally via a microprocessor unit( MPU), memory, and some peripherals. These devices are optimized for embedded operations that require both processing functionality and agile, responsive interaction with digital, analog, or electromechanical components. The most common way to refer to this order of integrated circuits is “ microcontroller" but the abbreviation “ MCU ” is used interchangeably as it stands for “ microcontroller unit ”. You may also occasionally see “ µC ”( where the Greek letter mu replaces “ micro ”). “ Microcontroller ” is a well-chosen name because it emphasizes defining characteristics of this product category. The prefix “ micro ” implies smallness and the term" regulator" then implies an enhanced ability to perform control functions. As stated over, this functionality is the result of combining a digital processor and digital memory ...

Do you know what passive devices are? While engineers and designers within your association know, procurement personnel may not be up to speed with passive devices. However, you’ve come to the right place! If you’ve been involved with-procurement or supply chain processes and your curiosity about passive electronic components is anything but passive. At Rabyte, we empower purchasing departments and procurement specialists every day. And a little extra knowledge about those items on a Bill of Material( BOM) or invoice benefits everyone. Passive vs. Active Understanding Electronic element Functionality Most electronic devices and parts are distinguished by how they interact with electricity. In this regard, there are two main types Active components- Active electronic devices are suitable to manipulate electricity, plain and simple. suppose of diodes( basically, one-way electricity conduits) and LEDs as active electronic components. Transistors are another great example of an active de...

The semiconductor device electronics technology that drives all the devices in our factories, cars, homes, and pockets dates from the early Fifties, when the first bipolar transistors entered production. Transistors were fundamental structure blocks for sense circuits and computers because they could be used as binary devices that could be switched ON and OFF. They were equally useful in analog circuits similar as audio equipment or data acquisition systems because of their modification capabilities. The first electronic designs comprised transistors and other separate components, including diodes, capacitors, resistors, and inductors, assembled onto a PCB which could give electrical connections between the components as well acting as a mounting base. Simple circuits could be connected to achieve larger and more complex functions – but as complexity increased, so did cost, size, temperature, trustability issues and manufacturing challenges. This problem, occasionally known as ‘ the t...

Two factors that are essential to the operation of a vast range of electrical devices are diodes and rectifiers. Without them, the electrical current could flow back into other components, causing damage or total system failure. This article looks at the difference between diodes and rectifiers, their separate workings and operations. Diodes the protection of ultramodern electronics As the simplest semiconductor device, diodes are generally two-pin components made from silicon or germanium. Their purpose is to allow current to flow in one direction while preventing it from flowing in the other. When installed in a larger system, the diode protects sensitive electronic parts from being subjected to the wrong amount or type of current. An introductory example is a television remote that has a compartment for two AA batteries. When the batteries are fitted rightly, the diode allows the current from the batteries to flow through the circuit in the remote, enabling the remote to be used ri...
