Part Number: TPS25750

Hi team,

Customer would like to design TPS25750 and they have some questions. Need BU's support to response.

1. why there is no 12V option in Application Customerization Tool (GUI)?

2. Customer needs 12V power source.

3. The mechanism asking power source from 5V boost to 12V is default configured by application customization tool or customer should program it by Host MCU?

4. Do we have any register can read USB input current in TPS25750?

Thanks

    12V is coming in a future update to the tool (currently scheduled to release at the end of the month). To get started, we included support the main PD voltage/power levels (5V-20V @ 3A, 20V @ 5A).

    Please be sure the system being designed is actually supported by the TPS25750. The device doesn't do high voltage source only, so make sure the customer is designing a DRP system. If it is a DRP system, then the TPS25750 automatically controls the BQ battery charger devices based on how the user configures the GUI.

    The customer can read the Operating Current back from the Active RDO Contract (0x35) register. The reference for that register is included in the TPS25750 HI Technical Reference Manual on ti.com
