Reading PMIC PF0100A OTP registers

[florinmaticu]

Hello !

We have OTP programmed the PMIC with the configuration attached in the picture.

However when we try to read one of the OTP registers and check the value we get different output

For example we have programmed the 0xB8 OTP register (SW4) with the value *0x72* and we read *0x7F*

Same for the 0xDC OTP register (VGEN6) where we wrote *0x0D* and we read *0x0F*.

Any help appreciated.

Best regards,

Florin

Hi florin maticu

You can double check your actual value of SW4/VGEN6 output voltage in you application circuit to check its right or wrong.
