ACPL-K73L-020E

Optoisolators are devices that provide electrical isolation between two circuits by using light energy to bridge circuitry instead of a wire connection. The ACPL-K73L-020E is a type of optoisolator which is part of Avago’s optocoupler line, and is intended specifically for logic output applications. Its main features and capabilities, including its working principle, will now be discussed.

Application Fields of the ACPL-K73L-020E

The ACPL-K73L-020E can be used in a wide variety of applications, including:

• Light switches
• Joysticks
• Automotive control systems
• Home and industrial automation controllers
• Factory automation systems

The ACPL-K73L-020E is well-suited to these types of applications due to its robust construction and 5kV of isolation voltage, ensuring a safe and reliable operation.

Working Principle of the ACPL-K73L-020E

The ACPL-K73L-020E utilizes light-emitting diode (LED) technology to bridge a gap between two circuits. When a signal is input into the LED, it is converted into a light beam which is monitored by the photodetector portion of the optocoupler. The optical signal is converted back to an electrical signal which is output to the desired circuit, resulting in a signal that has electrical isolation from the input circuit. This allows for increased safety and reliability because the input and output signals are completely isolated from one another.

The ACPL-K73L-020E also utilizes a dual-channel photodetector to detect both the forward and reverse bias of the LED, allowing for more accurate signal detection and output. This ensures that the output signal is the same as the input signal, allowing for a more reliable operation.

Conclusion

The ACPL-K73L-020E is an excellent choice for logic output optoisolator applications. Its robust construction, 5kV isolation voltage, and dual-channel photodetector ensure that it is reliable and safe to use. Furthermore, its small size and low power consumption make it a great choice for applications that require a small form factor and low power consumption, such as light switches and joysticks.
