ISO7741-Q1: Schematic review

Part Number: ISO7741-Q1

Tool/software:

Hi team,

Please help review whether the power supply of ISO7741-Q1 is reasonable. If there is any need for improvement, please point it out.

The two schematics are two independent power supply methods and the power supply ports of ISO7741-Q1 are marked in the figure.

Best Regards,

Jade Lan

    Hello,

    Thanks for reaching out. 

    Overall the schematic looks good, please make sure that the 100nF decoupling capacitors are no more than 2mm away from the digital isolator VCC pins on the actual PCB layout. The supply pins also look good. if you need future help for PCB review, please feel free to reach out!

    Regards,
