    The hidden cost of optocouplers for isolated RS-485 designs

    Optocouplers, also known as optoisolators or photocouplers, have been used to achieve galvanic isolation in electronic circuits for more than 40 years. Optocouplers use an LED and phototransistor to enable signal communication without the transfer of current. Historically, optocouplers have been popular because they were a low-cost solution. However...

    Now that you have isolated your CAN signals, what about power?

    As I covered in my previous post , the use of the isolated Controller Area Network (CAN) standard is increasing in both industrial and automotive applications. With higher voltages being used in these end applications, isolated communications are becoming imperative when protecting the low-voltage microcontroller while also reducing noise. But just...
