Hello NXP Community,

I'm working on the PMIC OTP, MC33FS8530A0-ES. I came across these questions. Please help me with these.....

Q1. How do I determine the appropriate power sequencing and delay values for my PMIC ?

Q2. What are the key factors that determine the power sequencing and delay values for my specific NXP PMIC ?

Q3. What are the risks of not following the recommended power sequencing and delay values ?

Q4. Can you please provide me with some general guidelines on how to set the power sequencing and delay values for my PMIC ?

For your Q1-3,the power sequency and delay value is depend by your MCU requirement not the SBC side.

Q4 you can download the OTP FS84 / FS85 OTP Configuration tool for setting the delay and slot:
