TXU0304: UQFN 12Pin, how to know Pin1 when part populated

Mark Bolduan

Part Number: TXU0304

Tool/software:

Regarding version TXU0304RUTR with UQFN 12pin package: How do I know where Pin1 is, when the part is populated? There is just the Device marking 1J6 and some points visible. I do not find the information in the datasheet.

One remark: A Pin 1 Index Area as shown in the datasheet is not visible on the package.

There is a point at the bottom left (when the text is upright) that indicates pin 1. (The other points are a binary date code.)

Thanks! Is there any documentation from TI regarding the marking of Pin1 and the binary date code?

Hello Mark,

As Clemens said, Pin 1 will be located at the bottom left where the text is upright. See image below
