This document gives focus on optocouplers including its basic principles, operation, and common applications. Suggested techniques in order to maximize the device’s efficiency are included. Cases ...

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 ...

Standard optocoupler speed is limited mainly by the relatively slow response of the phototransistor. This Design Idea adds components to the LED drive side to speed things up. Figure 1 The speed-up ...

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 ...

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 ...

Debuting as the first in a series of isolated gate-driver optocouplers from NEC, the BiCMOS PS9552 optocoupler delivers up to 2.5A of output current with reportedly high common mode transient immunity ...
