TPS22964C: TPS22964

Part Number: TPS22964C
Other Parts Discussed in Thread: TPS22953, , TPS22963C

Hi Team,

I found in the data sheet of TPS22953 application note in the data sheet (page 32, 10.1.6 section) connection of 2 parts of TPS22953 with 2 USB inputs and one output.

Can I do it with TPS22964C instead of TPS2253? I asked because the size of TPS22964C is much smaller.

If not can you recommended other smaller part.

What the functionality different between TPS22964C & TPS22963C?

Thanks,

Shlomi

    Hi Shlomi,

    Thank you for reaching out to the E2E forum.

    I would first like to answer the difference between the TPS22964C and TPS22963C. The TPS22964C has the feature of Quick Output Discharge (QOD) which keeps a pull down resistor on the output when it is off. For this reason the TPS22964C is not recommended for this configuration.

    The TPS22963C in the other hand does not have QOD. This means that the TPS22963 could be used to power multiplex with a different configuration, but it would not be an automatic switchover. You would have to include an additional enable signal for the load switches. An article online that might be worth to look at would be Power Multiplexing Using Load Switches and eFuses (http://www.ti.com/lit/an/slva811a/slva811a.pdf). This article contains the configuration needed for this type of load switches explained in detail.

    I can suggest some parts for power multiplexing depending on your requirements:

    • Size
    • Switchover method(Manual or Automatic)
    • Acceptable output voltage drop
    • Current needed

    Regards,
