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 ...

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 ...

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 ...

Optocouplers are widely used in providing galvanic isolation because of their true isolation characteristics. The heart of a modern optocoupler is an input infrared-emitting LED and an output ...
