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!

Best,
Manuel Chavez
