Part Number: TPS650864
Other Parts Discussed in Thread: TPS650861

Hi

Customers using Xilinx® MPSoC designs are looking for corresponding PMICs.

It seems that TI TPS650864 is specifically designed for this Can I discuss further. Clarify the design issue?

The power requirements are as follows:

1. PMIC for Xilinx ZU5CG (MPSoC) sequence tunning and reference circuit

2. 3-cell Li battery charger with power path

    Hi Gareth,

    Thank you for reaching out - you are correct that the TPS650864 variants are targeted towards Xilinx. TPS6508641 is specifically targeted for ZU2-ZU5 range and would likely be a good fit. The details of this NVM spin are covered in section 8.5 TPS6508641 Design and Settings of the datasheet, including connections and sequencing. 

    If a customer is looking for further customization, the TPS650861 is the user programmable version. There is an NVM generator for the TPS6508641 that they could adjust to make minor changes (or large changes) if desired: https://www.ti.com/lit/zip/swcc025 

    Arrow even offers programming services if the customer does not want to program the units themselves.

    For reference design, the TPS6508641 was used on the Ultra96-V1: https://www.element14.com/community/servlet/JiveServlet/downloadBody/91035-102-1-377563/AES-ULTRA96-G_2018-03-19.pdf 

    As far as battery charger - I would recommend starting a new post to be directed to the battery charging team.
