TPS659037: PMIC IC DEFAULT OUTPUT VOLTAGES

kalpana gogineni

Part Number: TPS659037
Other Parts Discussed in Thread: AM5718

WE ARE USING TPS6590379 PMIC FOR SITARA PROCESSOR (AM5718) IN OUR DESIGN.

WE HAVE PLACED BOOT0=0 (FOR DDR3L); BOOT1=1 THEN WHAT ARE THE DEFAULT OUTPUT VOLTAGES OF THE LDO'S AND SMPS'S REGULATORS OF THE PMIC(WHICH REGISTER VALUES IT WILL GIVE BY DEFAULT 0X96 OR 0X97)??

IN PMIC DATASHEET AND MANUALS THEY HAVEN'T MENTIONED ANYWHERE ABOUT SEL_0 AND SEL_1??

DOES THE PMIC TURN ON WITHOUT ANY PROGRAMMING? .

Hello,

The PMIC will not turn on if it has not been programmed but this should be done at Final Test prior to being shipped.

I have attached the configuration files for both the 0x96 and 0x97 OTPs which say what the voltages are for the various regulators as well as the power sequencing and some register content.

Hello,

I would recommend reviewing the TPS659037 User's Guide to Power AM574x, AM572x, and AM571x which covers this specific OTP variant for use with the Sitara processors.

Best regards,
