AWR1642: RFLDOBYPASS_EN for AWR1642

Guru 16800 points
Part Number: AWR1642

Hello,

RFLDOBYPASS_EN of AWR_RF_LDO_BYPASS_SB is found in the "AWR1xx_Radar_Interface_Control" document.
My customers want to use this function for AWR1642; however, I cannot find the way to set this and corresponding register in TRM.
Please let me know how to use this function for AWR1642.

Best Regards,
Nomo

  • Hello Nomo,

    You can set this through the provided API. The function to enable/disable LDO bypass mode is rlRfSetLdoBypassConfig. This function is one of the Radar Sensor Control APIs, found in section 10.2 of the AWR1xx_Radar_Interface_Control document.

    It is also one of the configurable options through the Radar Studio GUI.

  • Hello Adrian-san,

    Thank you for your reply.

    I'm referring the following doxygen; however, I cannot find the "rlRfSetLdoBypassConfig" API.
    C:\ti\mmwave_sdk_01_01_00_02\packages\ti\control\mmwavelink\docs\doxygen\html\group___sensor.html
    In rl_sensor.h in SDK, the rlRfSetLdoBypassConfig API is described.
    Does this API work properly?

    Best Regards,

  • Hello Nomo,

    You can find more information about this API in the  AWR1xx_Radar_Interface_Control in the DFP. I don't think it is mentioned in the Doxygen.

    Sure, the API works properly. If not, we would not include it. Currently, all of our EVMs are using LDOs but we do have some devices releasing in the future that will utilize the LDO bypass and be powered directly through the PMIC.
