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 ...

The circuit was designed to formulate a timer that can provide an alert method with the use of a buzzer while the presence of the optocoupler will make it possible to drive an external circuit. 4060 – ...

Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. The ...

Dusseldorf, Germany: The PS9402 insulated gate bipolar transistor (IGBT) drive optocoupler from Renesas Electronics integrates IGBT protection. It comprises a gallium-aluminium-arsenide (GaAlAs) LED ...

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 ...

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 ...
