MPQ4242 OTP programming

DC-DC Power Converters

Hello,

I’m trying to program the MPQ4242 using a separate microprocessor which has I2C. I can read and write to it, however the trouble I run into is getting the clock to run and checking that it’s on. I can bypass this by plugging in a sink device but I’d like to be able to do it with coding.

I’m also at a roadblock for actually confirming the configurations, register 0x2F in the datasheet says a password is required. Can anyone share the password and how to use it? Do you do a separate write before doing the confirmation?

Hi Abraham,

Just got an update on this email from one of our sales, I will be following up on that via email to you. Apologies for the delay in getting back to you, I am working to draft a response to you.

Thank you for the patience.

Regards,
Adhish
