Optoisolators, specifically Logic Output optoisolators such as HCPL-2601#060, are devices used to protect sensitive systems and prevent signal feedback in on/off control applications. They are composed of a light source that is typically a Light Emitting Diode (LED) facing a photo sensitive device like a photo detector or a transistor combined with a complementary output as necessary for applications. In this article, we will be looking at the applications and working principle of the HCPL-2601#060.

What Are the Applications of HCPL-2601#060?

Optoisolators are designed to isolate either control or sensing devices, providing efficient and reliable operation in harsh industrial environments. The HCPL-2601#060 can withstand 3,000 voltage isolation without any signal degradation. This allows it to be used in standalone low-power applications for equipment ranging from factory automation systems to building security systems.

The tiny package of the HCPL-2601#060 makes it suitable for mounting on smaller surface and height. Its wide 6.35mm pitch with four contacts makes it easier to insert and mount, and it also complies with UL and IEC standards for high voltage isolation. It is ideal for applications where the power characteristics of the system require tight voltage isolation and high temperature stability.

The HCPL-2601#060 can also be used in automotive systems such as remote key-less entry applications, vehicle immobilizers, and tire pressure monitoring systems (TPMS). Its high current transfer ratio (CTR) of up to 100% at full power ensures reliable operation and reduces system integration complexity, which makes it an ideal solution for secure automotive control systems.

What is the Working Principle of HCPL-2601#060?

Optoisolators work by converting electric signals into light signals, and using photoelectric effects to isolate the two systems. The HCPL-2601#060 works using a principle called Coupled PhotoEmission or CPE. In this process, a power transfer takes place between two electrically isolated copper surfaces. The input signal is used to drive current between the two electrically isolated surfaces. The current flowing on one of the surfaces creates a light signal that is transmitted through an optical waveguide to the other surface.

Once it reaches the receiver side, the light signal is converted back into current, allowing the output circuit to be fired. The photo sensitive receiver is then used to detect the light signal and convert it into a control voltage. This voltage can then be used to control other devices and circuits.

The HCPL-2601#060 is designed to provide isolation between electrical systems from 3,000v. It also features current transfer ratios of up to 100%, as well as fast switching speeds of 10 nanoseconds. It can operate at temperatures from -55 °C to +125 °C, making it ideal for use in harsh industrial environments.

Conclusion

Overall, the HCPL-2601#060 is a reliable, high voltage optoisolator ideal for use in harsh industrial environments. Its wide range of applications makes it suitable for low-power and automotive control systems. Its working principle of Coupled PhotoEmission makes it an efficient solution for conversion between electric signals and light signals. By providing up to 3,000 voltage isolation with fast switching speeds, the HCPL-2601#060 is a great solution for both control and sensing devices.
