Hi all,

I'm using TLI4971-A505T5-U-E0001 to measure current of H bridge DC motor. I want to use Aout in Analog output mode. But when motor start, sometime Aout jump in to Communication mode, that makes analog reading wrong.

Can you give me the troubleshooting?

Thanks!

Dear support,

I have got a couple of questions regarding the magnetic operating conditions of the device.

The IC will be used in a configuration with back-biasing. 

The following operating conditions are stated in the datasheet of TLE4953C:

1. Pre-induction: +/- 500 mT
   My understanding ist, that the dynamic range is maximum +/- 500 mT on all three channels (L, R, C) and for me as an integrator I have to ensure that this limit is not exceeded, even at the minimum possible air gap? Basically the flux density has always to be below +/- 500 mT for all three hall elements? Is this understanding correct?
2. Pre-induction offset between outer probes: +/- 20 mT
   Suppose the dB = L-R signal is non-symmetrical. The positive peak is 42 mT and the negative peak is 0 mT. The peak-to-peak value would be within the specification, but there would be an offset of 21 mT present. Does this limit refer to (max(dB)-min(dB))/2<20 mT? If my understanding is correct, I would not maintain the allowed operating range? 
3. Pre-induction offset between mean of outer probes and center probe: +/- 20 mT
   Basically same question as point 2.  I calculate based on this equation dBdir = (L+R)/2-C the differential directional signal and check (max(dBdir)-min(dBdir))/2<20 mT? Is this again the correct approach?  I attached some simulation results for a non-symmetrical Bdir case (upper plot raw flux densities, then dB and dBdir).
4. Differential: +/- 120 mT
   Does this value refer to the positive and negative peak of the dB = L-R signal?
5. Note: Limit threshold speed 0Hz ≤ f ≤ 2500Hz +1.5 mT. The stated condition is 50% missing pulses. Is there as well a flux density limit for which let's say 99.99966 % of all pulses are detected. I used guard banding by using dB >= 4 mT as the allowed lower limit for the simulation, but I am not sure what the expectation for the missing pulses would be.
6. Note: Limit differential direction signal 0Hz ≤ f ≤ 1100Hz +0.73 mT. The stated condition is: "just one pulse missing out of 100". Does that mean, there will be no directional pulse width shown on the output for this single pulse or the entire pulse is missing?

 Thank you for your support.

Hi

I am running

MCU V2.2 03/2020

Shield V2.0

RadarBaseboardMCU7_v2512.bin

SDK v3.4.0

RadarFusionGuide v3.3.0

I try using Matlab  MatlabWrapperConnectOnly.m

in the example files and get the error code "no compatible device found (IFX_ERROR_NO_DEVICE)"

I looked around here and read posts about version issues compatible to the SDK. I think my hard/firmware is up to date, 

I just uploaded the newest firmware

Any idea what could be the issue?

Thanks

Hello. The issue I inquired about last time has been successfully resolved, thanks to your previous advice.
I have one more question I'd like to ask.  /  (using sensors: TLE493D-W2B6 A0, A1)

When a magnet is placed near the sensor, the values are consistently received. However, when the magnet is not near the sensor, I believe values close to 0 should be measured.
But, values close to 0x00 and 0xff irregularly appear when the magnet is not near the sensor.
I don't understand why 0xff values are coming in. Is there a reason for such extreme differences in values to periodically occur when there is no magnetic presence near the sensor?
Or are there certain initial settings that need to be done to prevent this? Currently, I believe I can handle this through exception handling, but I'm curious, so I wanted to ask.

TLE493D-W2B6 A0  TLE493D-W2B6 A1 

I am using the Arduino IDE's Cartesiar sample program, but it cannot effectively detect the position. I don't know where the setting is wrong. The execution result is as follows:

Hello,

I have KIT_CSK_BGT60TR13C and I want to test the sensor for presence detection. There are some parameters to set, shown in the following tables:

I've understood  that hight sensitivity could be good for detection micromovements, max_range is the limit in terms of meters for the detection and the thresholds allow to detect the presence or not.

Moreover with setting the mode you could see only micromovements, only macromovements or both.

1.Do you have any experience with this component?

2.Could you suggest me an example of setting for detection face micromovements?

3. Is there a report after the test (with all the information that I have used)?

4.Do you know if on Modus Toolbox and for KIT_CSK_BGT60TR13C is available this : 

Thanks a lot for the support.

Best regards

Hello,

we are planning to use the upcoming BGT60UTR11AIP in a new development project. Is there any information regarding countries that do not allow the deployment of 60GHz radar sensors or just allow certain frequency bands/ranges? This seems to be the case for 120GHz radars if i am informed correctly... I have also heard of countries that require radar sensors of certain frequencies to be registered. Regarding this is there anything to keep an eye on with this new chip?

Thanks.

 Regarding the BGT24LTR11N16,
please let me know if the VCO output can oscillate when the input range of V_TUNE is 0V to 3.3V(Vcc).
Alternatively, please tell me the input voltage range of V_TUNE for BGT24LTR11N16.
　In fact, when I applied 0 to 3.3 (VCC) to V_tune in the environment of -30℃ to 75℃ and observed the BGT24LTR11N16TX output with the spectrum analyzer, I was able to observe the oscillation output at any temperature.

On the other hand,
In the datasheet of BGT24LTR11N16,
at the section 2.4 TX Section, it is stated that "Tuning voltage to cover VCO frequency range" is 0.7V to 2.5V.
Another specification item "VCO frequency range" was 24.05 to 24.25GHz.
As an interpretation of the above specification,
I interpreted "Tuning voltage to cover VCO frequency range" as the voltage range specification to cover the "VCO frequency range" specification.
Is this interpretation correct?

In addition,
For my application,
There is no problem with lower TX output level.
There is no problem due to the temperature characteristics of the oscillation frequency, and it is a good use as long as the oscillation output is produced.

I don't have the sufficient information of the VCO internal circuit of BGT24LTR11N16,
but it is a BiCMOS  MMIC,  and is estimated to be an LC Voltage-Controlled Oscillator using a Variable Capacitance Diode.
If so, V-tune would be able to oscillate in the range of 0 to 3.3V (VCC), and the experimental results would be understandable.
Please support me regarding the above.
