Functional security analysis

Other Parts Discussed in Thread: OPA388

I need to do functional safety analysis (TI), but the failure mode and failure rate distribution can not be provided by the TI. Do you have any suggestions on how to perform functional safety analysis?

Hello Meng,

In general, for any device you have selected, go to the Product Folder page and click on the Quality & packaging tab. This will bring up a page with DPPM/MTBF/FIT Rate, click on the View link, the reliability data will be displayed. For example, here is the OPA388 page: www.ti.com/product/OPA388/pinout-quality .

Part number	ELFR-DPPM	MTBF	FIT	Conf level (%)	Test temp (°C)	Sample size	Fails	Usage temp (°C)	Conf level (%)	Activation energy (eV)	Test temp (°C)	Test duration (hours)	Sample size	Fails
OPA388ID	16	5.03x 10⁹	0.2	60	125	57882	0	55	60.0	0.7	125	1000	58737	0

I think this is the information you are looking for, based on your inquiry. You will have to perform this process for each device you have in your design.

Regards,

~Leonard

What I need is the failure mode of a chip and its percentage distribution.
