LDC1001: OSC status.

Kengo.Y

Part Number: LDC1001

Tool/software:

Hi team,

OSC status becomes 1.
What could be the reason for this status to be 1?
If the IC was swapped to another device, the OSC status is 0.

Hi Kengo-San,

Thank you for posting to the sensors forum.

Today is a holiday in the US and our team is out of office. We will do our best to provide a response by end of day July 5.

Best regards,

Jesse

Hi Kengo-san,

According to the LDC1001 datasheet, OSC status value of 1 indicates sensor oscillation timeout. This can be caused by a sensor with an Rp below Rp_MIN or setting Min Sensor Frequency too high.

Best regards,

Jesse

Hi Jesse-san,

Thank you for your reply.

When I replace the IC, the problem recovers.
In other words, I think the IC has broken, but I would like to know which circuit breaks and this bit becomes 1.

Hi Kengo-san,

Can you share a register dump of the device to show the configuration settings? Also, can you provide an oscilloscope capture of the INA/INB pins?

Best regards,

Jesse
