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

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 ...

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 ...

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 ...

Designers of switch-mode power supplies generally put a lot of care into selecting the placement of poles/zeros of the supply transfer function to ensure stable operation. However, many such designs ...

• 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 ...

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 ...

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 ...

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 ...

Avago Technologies has introduced a low power 10MBd digital CMOS optocoupler, which it claimed has the lowest power consumption of a device of its type. Supply current is under 1.5mA over the –40 °C ...
