HCPL-5650 Isolators

The HCPL-5650 is an optoisolator manufactured by Avago Technologies in 2010. It is part of the Optoisolators - Logic Output category, and is designed to provide galvanic isolation for logic signals up to 100 Mbps speed. This design also allows for high speed response and enhanced noise immunity.

Optoisolators are electronic components that use light as a means of communication and electrical isolation between two subsystems. This results in high noise immunity without affecting the electrical characteristics of the signal. This makes them a useful tool for protecting against electrical noise generated from motors, relays, etc.

At its core, the HCPL-5650’s design is based on an LED optically coupled to an integrated photodetector. The LED provides the input to the device, while the photodetector provides the isolated output. In the device’s turn off state, the output from the photodetector is minimal which disconnects the two subsystems. When the LED is turned on, this process is reversed and the output from the photodetector is increased, providing a path for the logic signal to traverse between the two systems.

The HCPL-5650 is suitable for a broad array of applications in both industrial and consumer electronics. Its small footprint makes it ideal for space-constrained systems, while its high speed response time makes it suitable for logic signals. Its higher noise immunity also makes it ideal for more sensitive applications, such as battery-operated devices.

Potential applications for the HCPL-5650 include isolated data transmission, isolated power supplies, and systems with communications and signals from a variety of sources. It may also be used to protect sensitive circuitry from electro-magnetic interference generated from motors, relays, and other signals.

In summary, the HCPL-5650 belongs to the Optoisolators - Logic Output category, it provides galvanic isolation for logic signals up to 100 Mbps speeds, and its small size and high noise immunity makes it suitable for a wide variety of applications.
