App note: Optocouplers in on-board chargers and battery monitoring systems

App note from Vishay on how optocouplers play a role on safety for Electric vehicles. Link here (PDF) The number of electric vehicles on the roads is steadily growing, increasing the need for safe and reliable battery systems and high efficiency battery chargers. Modern electric vehicles use battery systems with voltages up to 1000 V […]

App note: Replacing traditional optocouplers with Si87xx digital isolators

Digital isolator from Silicon Labs app note shows pin compatible plus high performance replacment of incumbent optoisolators, link here (PDF) Opto-couplers are a decades-old technology widely used for signal isolation, typically providing safety isolation, signal level shifting, and ground loop mitigation. They are commonly used in a wide range of end applications, including data communication […]

Android / Arduino controlled remote wall socket

Mario B√∂hmer has informed us of his latest project, an Android/Arduino controlled wall socket. Mario writes: To show the basic principal I used a remote wall socket which normally is switched with a remote via a radio frequency of 433 MHz. What I wanted was to have an Arduino controlling the remote switch to turn […]
