DRV8256: reliability testing?

AnBer

Part Number: DRV8256

Team,

Customer would like to understand better the DRV8256 specific tests that relates to the our "reliability testing" TI.COM page:
https://www.ti.com/support-quality/reliability/reliability-testing.html
https://www.ti.com/quality/docs/estimator.tsp?opn=DRV8256PRGER&cpn=&partNumber=DRV8256PRGER#resultstable

Can we share some details about the actual "reliability tests" that have been performed on DRV8256?
Has some load been applied to output during those stress tests? What has been measured?
Can we share some number/figures of the test results?

Thanks in advance,

Hi AnBer,

The reliability tests are generic tests with device specific char and validation data. The two pages you linked provide all the information the customer needs to understand the reliability tests. The characterization test conditions are given in the electrical characteristic table.

Hi both,
thank you for bringing this question in the forum.

Looking in the links it is still not completely clear, or hard to understand the way testing is executed from functionality side.
To simplify the question, is there any load connected to the chip (as it is a motor driver), or just a powered chip? How is functionality of the chip validated?
Thank you!

For some reliability tests, the driver was loaded. An example would be HTOL (high temperature operating life). for other tests, the driver is not loaded. You can find the list of qualification tests performed for this device and the test standards used for each one (https://www.ti.com/quality-reliability-packaging-download/report?opn=DRV8256PPWPR)

The link above list all of he qualification tests and data for this device.
