TPS2595: PS for storage disk

Part Number: TPS2595

Tool/software:

Hi Team,

The customer's board has multiple memory disks, and they are concerned that when a memory disk is inserted into the slot, an overvoltage will be generated on the output side of the efuse. Therefore, want to confirm whether TPS2595 is suitable for this occasion? Are there any other recommended devices? Thanks.

Regards,
Hailiang

  • Hi Hailiang,

    My concerns: 

    • Reverse current can flow due to that overvoltage 
    • Abs max of device can be violated.

    What are the operating conditions? If Vout overshoot is concern, we can clamp the overshoot using TVS diode. Also reverse current blocking might be required and TPS2595 doesn't provide that. Is customer fine with reverse current flowing? 

    Best regards,
