AWR1642: Thermal shutdown function on AWR1642

Nomo

Part Number: AWR1642

Hello,

Does AWR1642 have thermal shutdown functions?
In case AWR1642 has thermal shutdown functions, are these operated by the hardware or the software?
My customers want to know they can change the threshold of the temperature for the function.
If they cannot control the threshold, please let us know the what temperature is set.

Best Regards,
Nomo

    Hi Nomo,

    Please checkout the AWR1xx Radar Interface Control (ICD) document:
    software-dl.ti.com/.../AWR1xx_Radar_Interface_Control.pdf

    If you go down to 7.2.1 Sub block 0x01C3 – AWR_MONITOR_TEMPERATURE_CONF_SB. You can see that the temperature reporting mode supports three different modes of operation:

    REPORTING_MODE = 0 - Report is sent every monitoring period without threshold check
    REPORTING_MODE = 1 - Report is send only upon a failure (after checking for thresholds)
    REPORTING_MODE = 2 - Report is sent every monitoring period with threshold check

    Below that are the various TEMP_ THRESH_MIN and TEMP_ THRESH_MAX both for the analog and digital subsystem temperature monitors. Going to a REPORTING_MODE = 1 setting and setting the various TEMP_THRESHOLD fields should allow for the voltage temperature monitoring you need.

    When commanded to do so (through interface commands) this monitoring is performed by the ARM R4 core of Radar Sub-System (RadarSS).

    Please let me know if that answered all of your questions on this topic.


    Thank you,
    Randy
