TMAG5173-Q1: Part experienced a periodic failure, 11 sequences of ~50ms then recovered

Hi Brett, 

Thanks for posting to the Sensors forum!

Would it be possible to get a waveform (preferably from a logic analyzer) of the described behavior?

Best,

~Alicia

It is not a friendly environment for a logic analyzer. Here is the data we read from the X-Axis of the 2 sensors (176 and 180) along with the CONV_STATUS RESULT_STATUS bit and CRC error detection bit. I have highlighted the recovery sections where no errors were logged or the new error sequence started. The rotation collections are happening every 1.282 milliseconds (780 Hz).

Hi Brett,

In you initial post, you mentioned that:

Brett Steinicke said:

The sensors could experience significant shock and vibration.

Could you please expand on what this entails? Does the part only start experiencing the behavior that you are seeing only start occurring after experiencing 'significant shock and vibration'? Or is it the case that this behavior is always being seen?

Started after significant shock/vibration. We have not reproduced this error yet, but we have not targeted nor applied specific tests to reproduce it. The sensor recovered at rotation 3358218 and operated without problems thereafter. We are curious about the periodic nature of the 11 sequences. This image shows sensor 176 in red with neighboring sensors.

Hi Brett,

Just to clarify, what is causing the shock/vibration, could you explain a bit more as to what you mean by this? Is the part undergoing some kind of electrical shock?

Electrical shock is not likely (a possibility, yes) this would be a physical event happening to the sensors shown towards the left of the chart. This is a pipeline inspection tool. The pipe wall is saturated with a permanent magnet and the sensors measure the decaying magnetic field. This vibration is where the sensors pass through a joint between to pipe segments where the thickness varies by 0.05 inches. 

Hi Brett,

Thank you for the additional information. I will discuss this with my team and get back to you by the end of Wednesday.

Hi Brett,

To clarify, is the behavior that you are seeing occurring only on the 1 device, or it is happening on other devices? Also, are the pullup resistors on the I2C line close to the sensor or the MCU? 

You mentioned that the sensor did not lose its configuration previously. Were you able to read the device register settings during this abnormal behavior? During this sequence, is it the case that all registers read back 0xFF? Including the DEVICE_ID and MANUFACTURER_ID registers?

Best,
