TPS25750:

GILFERD GONSALVES
Prodigy 10 points
Part Number: TPS25750
Other Parts Discussed in Thread: TPS25751

Tool/software:

1. If we are using TPS2575D as standalone PD source for smartphone charging, can the TPS2575D be used standalone in this application without using a battery or a BQ charger IC?

2. Is it mandatory to connect an external EEPROM or flash to the TPS2575D to define PDOs like 5V/3A, 9V/2A, 12V/1.5A, etc.? Or does the IC support default PDOs without EEPROM.

3. Can the TPS2575D be used as only source in a charging adapter application?

    Hi Gilferd,

    We do not recommend anyone use the TPS25750 for new designs. Please consider using the TPS25751, the direct successor.

    I will respond to the following questions with respect to the TPS25751.

    The TPS25751D currently only supports Source only with non-BG devices for 5-V source applications only. You are asking about higher voltages in question 2, so I think the answer to this for your use case is no.

    Yes

    No, the TPS25751D currently cannot be used as a source only in charging adapter applications.

    Thanks and Regards,
