Optoisolators, also called optocouplers, are an important class of devices utilized to provide isolation between two circuits, namely, an input circuit and an output circuit. Optoisolators accomplishing this task are typically made of two subassemblies, one being an emitter and the other being a photo-transistor, sharing a common optical interface. As such, optoisolators have a wide range of applications, including in industrial applications, logic circuits, and communication systems. One such optoisolator device is the HCPL2611SD. This article will discuss the application field and inner workings of the HCPL2611SD.
Applications
The HCPL2611SD from Avago Technologies is a 6-pin dual channel logic-output optoisolators that integrates two PIN photodiodes and two photo-transistor outputs at 1 MBd data rate into a compact SMD package. Due to its small physical size, this optoisolator can easily be used in fairly tight spaces. Its compact design makes it well suited for applications where board space is limited, as is the case in many consumer electronics and automation technology. This includes applications such as isolated analog signal conversion, thyristor gates, and logic circuits.
Given its compact size, the HCPL2611SD can also be used in automotive, energy, industrial, consumer, and LED driver systems. In the automotive domain, this optoisolator device finds its uses in vehicle diagnostics, and in lighting and power control components. This is because it possesses very low propagation delay and excellent high frequency response, which makes it an ideal choice for reliable signal transfer in automotive systems. In the industrial sector, the HCPL2611SD’s logic output optocoupler can be used for isolated communication, control and protection circuits, and for protecting low-voltage logic circuits.
Working Principle
The HCPL2611SD consists of an infrared LED emitter and two photo-transistors, hence making it a dual channel optocoupler. The two channels are isolated from each other by a galvanic barrier. The device can operate at a common mode transient immunity (CMTI) of up to 20 kV/µs, thus providing a high degree of signal isolation.
The LED emitter gets its current from the input circuit when the input signal is high. Thus, when this happens, the LED starts to emit a beam of infrared light which is then detected by the two photo-transistors. The light received by the photo-transistors causes the current to flow through them, which in turn produces the output signal. As such, when the LED is on, the two output photo-transistors turn on and off depending on the level of the input.
The HCPL2611SD optocoupler is designed to handle up to 1 MBd data rate, and is also compliant with IEC/EN 60747-5-5 (Class B) for logic output requirements. It can be used at temperatures ranging from –40°C to +105°C, and has maximum output current of up to 10 mA. The device also has very low skew between channels, which minimizes the risk of improper output signals.
Conclusion
The HCPL2611SD optocoupler is a high-speed device designed for logic output applications. It has a wide range of applications, including in industrial and automotive systems, logic circuits, thyristor gates, and analog signal conversion. The device is compact, making it ideal for space-restricted applications, and can handle data rates of up to 1 MBd. It also provides reliable signal isolation, low skew between channels, and excellent high frequency response.
