Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a tube-like sound. It is known that the main feature ...

In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through ...

Southwest Research Institute has developed a high-reliability, high-voltage optocoupler for spaceflight applications. NASA has selected the device as a power interface between the Europa Clipper ...

Optocoupler biasing is a critical yet often overlooked aspect of isolated SMPS design. Ensuring proper biasing of both the LED and phototransistor sides of the optocoupler is essential for maintaining ...

The importance of signal isolation in high-voltage design The difference between optocouplers and opto-emulators Details on TI’s silicon dioxide (SiO 2) isolation technology Isolation is invaluable in ...

The above button links to Coinbase. Yahoo Finance is not a broker-dealer or investment adviser and does not offer securities or cryptocurrencies for sale or facilitate trading. Coinbase pays us for ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

Ludwig Zeller is a science-fiction author, except instead of words, his medium is product design. His latest creation, the “Optocoupler,” is a kind of miniature digital spa for future-frazzled brains.

VMI’s new High Voltage Optocoupler design allows for low voltage LED control of a high voltage diode. In a convenient surface mount package, VMI has minimized the size of an optocoupler with up to ...
