TPS2596: Inquiry About Alternatives for eFuse Board Development

Ömer Bektas

Part Number: TPS2596

Tool/software:

Dear Sir or Madam,

I hope this message finds you well.

I am currently working on the development of an eFuse board for fuse distribution in automotive applications. The specific requirements for this project are as follows:

  • Manual solderability
  • Output current (I_out) of at least 20A
  • Input voltage (V_in) of 12V

While reviewing the product catalog, I noticed that the only available option is the QFN package, which is not suitable for manual soldering.

Could you please advise if there are any alternative packages that meet these requirements? Your assistance in identifying suitable options would be greatly appreciated.

Thank you for your help.

Best regards,
Ömer Bektas

    Hi Ömer,

    Generally eFuses are not used for automotive fuse distribution applications. We don't have many automotive (Q1) grade eFuses. I am also unable to find good match in load switch or integrated ideal diode portfolio.

    Are you open to external FET + Hot-swap controller for this application?

    Best Regards,
    Arush

    Hi Omer,

    We think High side switch will be better solution. Let me add my colleague who can help in this.

    Hi Arush,

    Thank you for your prompt response and for suggesting the high-side switch as a potential solution.

    However, I prefer eFuses due to their diagnostic capabilities and features such as overvoltage clamping, programmable ILim, and Moniroing Courrent and Temperature. These functionalities are essential for the requirements of our project.

    I appreciate your assistance and look forward to any further recommendations you may have regarding suitable eFuse options.

    Best regards,

    Ömer

    Hi Ömer,

    Is 20A the nominal load current or does that account for inrush current?
