Hi team,

I want to know OPT3101 IOVDD power requirements.

Will OPT3101 IOVDD be damaged if the power in IOVDD are not monotonic power up?

Thank you,

Hello Yishan,

If this is at start up only this should not be an issue.

Thank you,

Hi Joseph,

Do we recommend add ESD/TVS devices in IOVDD?

Thank you,

These devices are not specifically required but I would recommend them, especially true if you are using a Lazer emitter of any kind as these are especially sensitive to esd in this application.

For reference our EVM which utilizes led emitters also uses TVS devices it its design as shown in the OPT3101 Evaluation Module User's Guide (Rev. A)

Thank you,
