This white paper discusses the use of hermetic optocouplers in military and space electronics applications. The use of hermetic optocouplers provide a highly reliable result compared to its plastic ...

In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through ...

For example, the PC817D optocoupler offers CTR ranging from 50% to 600%, depending on the specific part number and operating conditions. Designers must account for the minimum guaranteed CTR to ensure ...

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 ...

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 ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...

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 ...

Hybrid-electric vehicles must operate reliably under harsh conditions that demand special qualities on the part of power-conditioning electronics. Consider the electrical system for a hybrid-electric ...
