Part Number: TPS659037 Other Parts Discussed in Thread: AM5728 On the startup timing, when I2C access on several times by system side (AM5728), SMPS1 and SMPS2 output (AM5728 VDD_MPU input) voltage are changed at all such times.
(ex. 1.2V → 1.09V →…
Hi Livia,
Thank you for the additional information. To confirm, from the scope shot, is the VRTC voltage correct until it increases after RESET_IN? Does that correlate with any other regulators turning on?
Also, have you looked at the voltage on VBG during…
Hi Sudhanshu,
Can you clarify if this scope shot was taken any capacitance on SMPS6? All of the power regulators on TPS6590377 must have output capacitors for proper function.
Are the other rails in the power sequence enabling properly? Can you take another…
Part Number: TPS659037 Other Parts Discussed in Thread: AM5728 Intro:
We have a board based around Phy-Tec's AM5728-based SOM which contains the recommended TPS659037 PMIC. We are using Phy-Tec's kernel (4.19.79) and u-boot (2019.01) which are from the…

I have two questions: THIS IS VERY URGENT
1.) Pin K9 - RESET. Can I leave it unconnected or needs PULL-UP/PULL-DOWN?
2.) Pin F8 - REGEN1. Can I leave this pin unconnected or needs PULL-UP/PULL-DOWN?
Please advise
Thank you

Hi,
When using a supervisory circuit to initiate the power down sequence of the TPS6590379 should it be connected to reset pin (K9) or the enable pin (J5)? I want to ensure the proper shutdown of the PMIC (and the attached AM57xx…
Part Number: TPS659037 Hello Ti,
This is Milav Soni From Teq Diligent, India.
We have build a custom board which have " AM5716AABCXA " processor and " TPS6590379ZWSR " PMIC available.
I have one question regarding designing.
As per H…
