DRV8910-Q1: AEC-Q100-012 Short-Circuit Reliability Test Results

Hello again!

We do not have the results for the DRV8910.  The testing was never conducted to the standard.

These are the results for the DRV8244.

We pass up to 1 million cycles to meet grade A.

Hello again!

That is correct.  The "AEC-Q100-012 Short-Circuit Reliability Test" is a specific test.  We conducted normal short circuit testing on the device, just not to that many cycles.

HoJo-san,

We test over the operating temperature range of device over the entire recommended voltage range of the device.  <10 units are used in the testing.  <100 cycles are conducted.  

You will note that there are limitations on the deglitch time allowed for OCP based on voltage range.  These limitations were discovered during our testing.

Please see above notes in the datasheet.

Ryan

HoJo-san,

Sorry for the confusion.

Deglitch time is set in one of the device registers.  If expected device operation voltage is ever >28V, the setting for OCP deglitch must be 1us.  It is a manual write over SPI.  The device doesn't automatically switch.

Thermal shutdown is always operational.  It may be possible to go into thermal shutdown after repetitive shorts, but this depends on your board design and ambient temperature.  At higher ambient temperatures, it would be more likely to get a thermal shutdown with an output short.

Ryan
