In the schematic, the TMCS1133 Hall-effect current sensor is connected through the nets PPL_P1 and PPL_N3. However, I am unable to determine how these nets are connected to the LLC transformer and what current path is being measured. Could you please explain the connection relationship between PPL_P1, PPL_N3, the resonant capacitor network, and the transformer primary winding(s)? I would also appreciate an explanation of how the transformer secondary winding(s) are connected to the rectification and output stages, and how the secondary windings are configured. Thank you for your support.

Investigation: Upon debugging, I found that the target hsdiv2FreqHz is hardcoded to 50 MHz in the SOC_clocksEnable function ( soc.c ). When the system tries to configure this, the code execution halts at the following assertion inside the SOC_rcmConfigureHsDividerClocks function ( soc_rcm.c ): DebugP_assert(dividerVal &lt; 32); It appears that configuring the PLL for a 450 MHz DSP core clock requires a divider value larger than the maximum allowed (31) to step down to the 50 MHz target for HSDIV2. Workaround applied: As a temporary workaround, I modified the target hsdiv2FreqHz to 100 MHz. This successfully bypasses the assertion and allows the firmware to boot properly. Please note that my application does not use the LVDS interface . Questions: Is my workaround (changing hsdiv2FreqHz to 100 MHz) safe and acceptable, given that I am not using LVDS? If not, could you please provide a better or recommended workaround to run the DSP at 450 MHz?

Once the calibrations are performed, application will retrieve the calibration data from FECSS and save it to FLASH. User need to specify valid value. option should be set to 0. 0 - Save Disabled 1 - Save Enabled Restore enable - When Restore enabled option is set, application will check the FLASH for a valid calibration data section. If present, it will restore the data from FLASH and provide it to FECSS while configuring it to skip any real-time factory calibrations and use provided calibration data. User need to specify valid value which was used during saving of calibration data. option should be set to 0. and arguments will be ignored when restore option is enabled. 0 - Restored Disabled 1 - Restore Enabled RX Gain - Recommended value is 30db to 40db. Units: db Backoff - T X channel power calibration. Valid Range: 0db to 26db. Units: db Flash offset - Address offset in the flash to be used while saving or restoring calibration data. Make sure the address doesn&#39;t overlap the location in FLASH where application images are stored and has enough space for saving factory Calibration data. This field is don&#39;t care if both save and restore are disabled.Flash address range is 0x0 to 0x1FFFFF (16Mb) Actual Factory calibration data is of size 128 bytes. It is recommended to use last sector of flash memory starting with address 0x1FF000. Note: The flash offset should be greater than 1MB (0x100000h) for EVM. This check is only to make sure Appimage and ATE calibration data is not corrupted. For reference, this information is available in the SDK API guide linked here . We&#39;re having trouble using the Motion and Presence Detection demo with the I WRL1432 on our end, but we&#39;re still trying to solve this. My guess is that there is an issue with the firmware patch for the device. We&#39;ll get back to you in two days when we know a bit more.

I have some interesting observations regarding this problem. We noticed that the Vout analog instability occurs when the IC or its traces exceed a temperature of 50 degrees Celsius. To test this, I sprayed freeze spray (electronic refrigerant) to keep the Hall effect sensor and its traces at approximately 35 to 40 degrees Celsius. With the lower temperature, we experienced neither overcurrent false tripping nor analog output instability. We repeated this test several times, and the results were consistent, even when we increased the switched voltage. The instability or false tripping only presented once we stopped cooling down the Hall Effect sensorhttps://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1687297/tmp119-tmp119-temperature-accuracy-verification-methods-for-a-fully-assembled-product/6503196Tue, 06 Oct 2026 21:12:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9915328d-550f-4270-9b4e-404d080e0de8HarryGHello Shota, A temperature-controlled chamber or oil bath are ideal for using the most thermally uniform environment possible, especially if your system requirements follow stringent accuracy specs and you need to test the finished board across an entire temperature range. However, depending on your application and production/test flow needs, a routinely calibrated reference probe can be sufficient for ensuring the finished boards are meeting the system accuracy requirements on/near the assembly line. As long as the room the devices are tested in has a consistent temperature throughout the day, the calibrated reference probe should be sufficient.

Long-term drift characteristics of TMP119 during reel storage before assembly. Is there any data available regarding temperature accuracy drift after long-term storage on a reel? While there is no data on long-term storage, as long as the devices are kept within an environment below temperature defined in the datasheet, there shouldn&#39;t be any drift in device accuracy. Are there any recommended storage conditions or storage-duration-related considerations? Aside from storing in appropriate temperatures, there are no strict guidelines on storage aside from common practices such as avoiding ESD-heavy environments, etc. 2. Long-term drift characteristics after the device is assembled into the end product. Is there any data available on temperature accuracy drift over the product lifetime? This is available in Table 6.5 of the datasheet 3. Long-term supply availability of TMP119. Is TMP119 planned to remain in production for the long term? Are there any concerns regarding future discontinuation or migration to a newer device? There are no plans to EOL the TMP119. Please let me know if you have any additional questions.

Could you please share what your current register settings are? Do you have Trigger_Mode set to Alert_Pulse? Also, what is RSLT_ALRT set to? Is it set to 0b or 1b? If it is set to 1b and Alert_Mode is left at 0b, the device will be configured to send an interrupt once a conversion is completed which would result in another conversion.
