In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials ...

One of the newly introduced devices from Vishay centers on a compact tricolor light-emitting diode developed for use in systems where space efficiency and reliability are essential. LEDs remain widely ...

It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

Toshiba is targeting automotive applications with a high-speed analogue-output optocoupler. Comms in electric and hybrid-electric vehicles is the main target. TLX9309 is AEC-Q101 qualified and ...

Circuit designers are very familiar with optocouplers, also called optoisolators (and sometimes called optorelays, if configured for on/off mode). They contain a photon-emitting LED with a ...

Over the years we’ve seen several attempts at adding Internet connectivity to the lowly wired doorbell. Generally, these projects aim to piggyback on the existing wiring, bells, and buttons rather ...

Utilizing the photo-sensitive nature of silicon, VMI has created a line of hermetically sealed, high voltage optocouplers and opto-diodes in versions that can be assembled in series configuration for ...

• Improve signal integrity and reduce power consumption as much as 80% with pin-to-pin replacement to optocouplers. • New opto-emulators improve performance over end-product lifetimes with TI's ...

For the first time, researchers of the University of Twente (UT) succeeded in connecting two parts of an electronics chip using an on-chip optical link. A light connection can, for example, be a safe ...

The compact TLP754 optocoupler IC from Toshiba Electronics Europe provides a 5-kV rms isolation interface between an intelligent power module (IPM) and its control circuitry. The compact TLP754 ...
