VR5510 OTP

[ajnas-c]

Anyone please let me know the procedure for OTP on VR5510 PMIC? Is this programming done by I2C via a microcontroller, or is there another method?

Hello,

I hope all is great with you. Thank you for using the NXP communities.

In this case, you need Entering Debug mode.

The VR5510 provides a means of evaluating the device in Debug mode. Debug mode allows users, via the I2C interface, to access the OTP register set, modify the registers, and test device functions.

Please find further information at chapter 8.12 from datasheet.

I hope this information helps.

Regards,

David

Hi David,
Good Day!
In the debug mode, I can change the register values using the I2C interface, right?

Hello Ajnas,

You are correct, the debug mode allow you, via the I2C interface, to access the OTP register set and modify them.

I hope this information helps.
