TPS2553D: I think that the simplified schematic on page 1 of the device datasheet is not correct about Power Pad.

Hello guys,

One of our customers found one wrong point in TPS2552D/2553D datashet. It is simplified schematic on page1 of the device datasheet. The simplified schematic says the power pad of the device package is connected to GND. But the device package type is SOT-23(DBV) only and DBV doesn't have Power pad. We think it is forgotton to erace when TPS2552D/53D datasheet is made from TPS255X datasheet.

Could you please modify the wrong point when you update TPS2552D/53D datasheet?

Best regards,

Kazuya Nakai.

Hi Nakai,
Thanks for checking our datasheet , could you help to point out which page it is in the tps2552 datasheet?

Hi Michael,

TPS2552 datasheet is no problem. The problem is on page1 on TPS2552D/53D datasheet. I think SOT23 doesn't have power pad.

Hi Nakai,

We have check the tps2553 datasheet , I think your confuse is about the page 4 " pin function" . At the bottom of this table , we use "-" mean don't have power pad for these two part .
