TPS2660: OVP and reverse voltage protection

Part Number: TPS2660

On TPS26600, the datasheet only mentioned about overvoltage and reverse voltage protection at the input. Since there are back-to-back MOSFETs, can it also protect against overvoltage and reverse voltage at the output?

  • Hello Sharina,

    TPS2660 does not supoort reverse voltage at the output.
    For output reverse polarity protection, please have a look at TPS2662.
    "www.ti.com/.../TPS2662"

    This device is in preview and samples are orderable in small quantity from TI store.

    Could you please let us know what is application you require output reverse polarity protection.
    Is it on PXI system or other modules?

    This will help us to provide better feedback.

    Regards,
    Kari.

    I have looked into TPS2662, but the max current is only 800mA. May I know when is the release date for this part?

    I am planning to use something similar to TPS2662 for 5V 2A user power supply, which required overvoltage, reverse voltage and also overcurrent/short protection. Appreciate your suggestion.

    Thanks

    Hello Sharina,

    Could you please share your email so that we can share more details about TPS2662?

    Hello Sharina,

    For output reverse polarity protection >800mA, TPS2660 can be used with external protection.

    Please refer to the attached presentation capturing the output reverse polarity protection using TPS2660 at 2A.

    Can you please share where this output reverse and over voltage TPS2660 Output Reverse Polarity Protection Circuit_10282016.pptxprotection is needed?

    Regards,

    Kari.

    can you share yours instead? I will email you later on the details

    Hello Sharina,

    Send the application use case to "karikalan@ti.com".

    Regards,

    Kari.
