TPS25750: Questions of TPS25750

Part Number: TPS25750
Other Parts Discussed in Thread: TPS65988, TPS25751

Dear Team,

We have a product design architecture diagram as follows:
1. Under this architecture, power is supplied to two products, namely 5V and 15V USB-C IN, and USB-C OUT also outputs 5V and 15V respectively. When USB power supply is present, the battery will be charged at the same time.
2. When USB-C does not supply power, the MCU detects it and will be powered by the battery through the Charger IC. In Battery mode, the Vout is 5V.
3. This system requires uninterrupted power supply
I would like to ask if you have any recommended Chip (USB Sink, USB Source, Charger IC) that you can provide for reference. Thank you.

Many Thanks,

Jimmy

  • Hi,

    Depends on the port placement, suitable device for this will be 2x TPS25751 (single port controller) or 1x TPS65988 (dual port controller).

    Is this a power only design?

    If you don't have other question I can transfer this e2e to the BCP team.

    Regards
