Optoisolators provide an interface between a low-voltage signal and a high-voltage system. The ACPL-071L-060E device is an optoisolator device with a logic output, specifically designed to switch high voltages with very low output current with very high immunity to email interference. In this article we will discuss the application field of ACPL-071L-060E and its working principle.

Application Field

The ACPL-071L-060E is suitable for use in telecommunications equipment, powerline communications, industrial systems, and other precision applications. It is a highly-efficient device that can be used to convert low-voltage digital signals to higher-voltage digital signals. The device offers excellent electromagnetic noise immunity, and features a low input current (<1 μA) and low capacitance (<10 pF).

The device is designed to provide reliable operation in applications with high current density, high voltage peak values, and fast edge rates. It can be used in applications involving remote control, telecommunications, and industrial automation, as well as in embedded systems, where it is required to provide higher reliability and immunity to electromagnetic interference.

Working Principle

The ACPL-071L-060E optoisolator utilizes light-emitting diodes (LEDs) to generate an electrical signal when the input voltage is applied. When the input voltage is below the forward threshold voltage of the LED, the device does not generate any output. However, when the input voltage is above the forward voltage threshold, the LED is triggered and the device emits a light signal. The light signal is then detected by a photodetector, resulting in the generation of a digital logic level at the output.

The device incorporates an enhanced technique for resistance to electro-magnetic fields, which is achieved by shielding the light emitting diode with current limiting resistors, which provide additional noise immunity. The device also incorporates a supply lead to provide isolation from power supply noise.

The ACPL-071L-060E optoisolator features a low current input version, which can be powered directly from digital signals or with an external supply voltage. The high frequency, low power, and low voltage logic outputs make it ideal for use in embedded systems where high-speed signals are required.

Conclusion

The ACPL-071L-060E optoisolator is a highly efficient, low input current device that is ideal for interfacing between low-voltage digital signals and high-voltage digital signals. The device features excellent electromagnetic noise immunity and is suitable for use in high current density, high voltage peak values, and fast edge rate applications. The device is specifically designed to provide reliable operation, and can be used in a variety of applications, such as remote control, telecommunications, industrial automation, and embedded systems.
