TPS65987D: not recommended for new design and alternatives

Josko M
Intellectual 950 points
Part Number: TPS65987D
Other Parts Discussed in Thread: TPS25751, TPS55288, PMP40801, TPS65987, BQ25758

Tool/software:

Hi, 

in the meanwhile, the TPS65987D part has become status "is not recommended for new designs" and the TPS25751 is proposed as replacement for new designs. 

However, currently available information and reference designs suggest that the TPS25751 supports external battery charger controller ICs only.
Since the TPS65987D was paired in some reference designs with the TPS55288 and initial idea was to use and adopt the PMP40801 reference design with TPS65987D I have several questions:

  1. Can the new part TPS25751 be paired with buck-boost converters such as TPS55288 or it supports solely battery charger controllers?
  2. Can we get the roadmap information for the TPS65987D part and other USB-PD controllers from TI?
  3. When it be the End-of-Lifecycle for the TPS65987D?
  4. Can the battery charger controller be used and operate as standard buck-boost converter, it means without connected cells?

 We need the solution for the USB-C PD, 65W, 10~28V input voltage with following roles:
- power mode role: DFP (Source only)  
- data mode role: UPF (Device only)

Do you have any suggestions how this can be implemented with TPS25751 device?
If the TPS25751 is not suitable for this application do you have any other part that fits here?

    Hi Josko, 

    Thank you for reaching out!

    1- The TPS25751 does not have integrated I2C support for the TPS55288. The TPS25751 is best suited for DRP, sink-only applications, and battery charging applications. 

    2- Unfortunately, we currently do not have a direct alternate mode capable replacement available on TI.com at this time, and will keep you informed on any new updates for this portfolio. If you have more questions, please reach out to your local TI sales representative for information.

    3- The TPS65987/8 will not EOL. See TI's policy here.

    4- I will loop in our BQ experts to help with this question. 

    Best Regards, 

    Aya Khedr

    Hi Josko,

    BQ25758 is a dc/dc converter only.  It very similar registers to the BQ2575x devices.  There is firmware for TPS25751D and one of the BQ2575x devices.

    Regards,
