HI team.

My customer have a question about TPS659039-Q1.

How is the initial value of INTx_MASK set when TPS659039-Q1 is reset? (Reset is POR or HSRST)

The 'TPS659038-Q1 and TPS659039-Q1 Register Map' are marked with an X.

Please give detailed explanation.

Thank you.

Charles,

The fields that have an "X" in the reset column mean that those fields are defined in OTP. This means, depending on which part number you are using, the default will vary.

Resetting the device will restore it to the same settings as its initial startup.

Please let me know if you have further questions.

Thanks,
Nastasha

Hi Nastasha.

Thank you for quick response.

Is OTP required?

If the OTP setting is not made when the sample is provided, what data is entered in the initial state?

Thank you.

Charles,

OTP is required and completed at the TI factory before any units are shipped out. The settings are therefore already determined. On ti.com, you will see many different versions of the TPS659039-Q1 available for purchase. Each version has unique OTP settings.

Thanks,
Nastasha
