Q: TPS74801 vs TPS74801-Q1 by 1123732

The crux of the question I am facing is whether TI does anything different in design or test of the standard catalog IC and the automotive qualified Q1 IC

 

e.g.

 

1) Does the part have a different process?

2) Does it have a different (thermally enhance?) package?

3) Is it 100% tested?

The Q1 device meets the requirements of AEC-Q100 through both "binning"and testing per AEC-Q100. http://focus.ti.com/download/auto/newsletters/autosolutions_04-09.htm provides a general explanation. See below from that web page:

AEC-Q100 is an industry standard specification developed by major automotive manufacturers and suppliers, which outlines the recommended new product and major change qualification requirements and procedures. It details a set of stress tests, defines the minimum stress test driven qualification requirements, and references test conditions for the qualification of integrated circuits.

Features:

—Qualified at -40°C to 125°C (represented in the part number by the

"Q" designator) —180-day PCN period versus standard 90-day PCN meets

automotive minimum requirements —Q100 qualification data available on

request —Single fab and A/T site help avoid shifts in performance or quality
