Optoisolators provide isolation between electrical circuits, allowing a signal on one side to be sent to the other side while having no physical contact. The HCPL-261N#060 has a variety of excellent features and advantages, making it an attractive choice for applications across many industries. This article will discuss the HCPL-261N#060 application field and working principle.

The HCPL-261N#060 is part of the Broadcom line of optoisolators, specifically in the Logic Output category. It is an 8-pin, high-performance logic output photocoupler with a galvanic isolation barrier between the gate A and the gate B. It is capable of operating at temperatures ranging from -40 °C to 100 °C and has a peak output current of 40mA. The input of the HCPL-261N#060 is an integrated light source, an IC containing a Darlington transistor, and the output consists of an optically coupled open collector output.

The HCPL-261N#060 is used in a variety of applications, such as controlling PLCs, controlling systems such as heating, ventilation, and air-conditioning, and controlling signals in motor drives. Its features include high isolation capacity, fast response times, long-term reliability, low power consumption, and UVLO protection. It is also compatible with most logic systems due to its low power consumption and wide supply voltage range from 3V to 30V.

The HCPL-261N#060 optoisolator works in a simple way. The input is supplied with a signal which is then amplified by an integrated Darlington transistor. This signal is then mirrored into the output side and meets the photo-diode and LED components. The LED component is then activated and produces a light signal that is received by the photodiode, resulting in current which then switches the output. The result is an extremely low power signal, safe from electrical noise, and with high isolation between the two circuits. This makes the HCPL-261N#060 the perfect choice for applications that require a reliable and robust open collector logic output optoisolator.

In conclusion, the HCPL-261N#060 is a versatile optoisolator with a variety of features and advantages. Its broad application range and simple working principle allow it to safely act as an electrical isolator in many different devices. It is suitable for controlling PLCs, systems, and motors, has high and reliable insulation capacity, fast response times, and compatibility with most logic systems. With all these features combined, it is no wonder why the HCPL-261N#060 is one of the more popular optoisolators in the market.
