UA9638: UA9638 with Digital Isolator functions

Part Number: UA9638
Other Parts Discussed in Thread: ISO7720, ISO7820LL

Do you have any product supported "UA9638 with Digital Isolator functions"?

  • Hi Mark,

    To provide isolation protection with a UA9638, an ISO7720 can be used in between your microcontroller (MCU) and UA9638 for a two chip solution as pictured in the block diagram below.

    Is this a good solution for your system?

    Thank you,
    Manuel Chavez

  • Mark,

    If your application is for driving isolated differential signal lines, the ISO7820LL has internal receive and transmit buffers separated by an isolation barrier. This would reduce the solution to a single chip.

    I hope this is a helpful comment!
