PCA9450C on iMx8Plus custom design OTP programming

suvrat_chaturvedi — Wed, 15 Oct 2025 08:41:46 GMT

So we are developing the a SoC with iMx8plus MPU , taken reference from iMx8mplus CPU board so it is having a PMIC on the board which is needed to be one time programmed. So can we get any documentation or reference for OTP for PCA9450C PMIC also are there any software/tools to program the PMIC on the board?
Thanks in advance.

For the reference board you do not need to do any things

Thanks @Rita_Wang for the support, so i have verified the power rails from the PMIC and they are powered up.
