TPS25990: About MFR_MODEL (9Ah) of TPS25990

Gary Yang

Part Number: TPS25990

Tool/software:

Dear Sir：

Refer to the datasheet, read MFR_MODEL (9Ah): Read the part number of the chip. Block read ASCII values – “TPS25990” = 0x54, 0x50, 0x53, 0x32, 0x35, 0x39, 0x39, 0x30.

But my IC reads 0x54, 0x50, 0x53, 0x32, 0x35, 0x89, 0x80, 0x30.

Could it be a faulty IC?

I don't have TI tools to verify

Is there any other way to test it?
