MOTIX™ MCU Forum Discussions

  目前我们在使用 TLE9853时，想配置一下 LIN通讯的 LDF文件，下图是 vector的一个 LDF文件编辑器，不知道咱们英飞凌是否有相关的开发工具呢？

感谢支持！

Hi 

I am currently working on a project involving the TLE9879 MCU, and I am facing an issue with erasing a page of the code flash in my code. Strangely, I am able to program it successfully, but encounter a failure when attempting to erase it.

I would greatly appreciate any insights or suggestions regarding the potential reasons for this discrepancy. Your expertise and guidance in this matter would be immensely valuable.

Thanks

Hi,

I am currently working with the TLE9877 controller, and I am encountering an issue when attempting to run motor operation within a high-temperature range. Specifically, when I commence motor operation under these conditions, the motor enters a driver fault state, accompanied by the indication of a Phase 1, Phase 2, and Phase 3 short to Ground error.

When i start the motor without diagnostics(phase Open or short detection) then motor starting and running properly. but when i start the same with diagnostics function given by infineon then motor not starting attaching code snip. 

Observation :  This all test i'm doing at high temperature. This issue i'm facing when internal temperature is above 130 degree Celsius and if internal temperature is below 130 then motor working fine. Also attaching config.icwp file 

I kindly request your assistance in resolving this issue.

Best Regards,

Mohit

Hello I have a question about the low level driver for the TLE987x Microcontrollers. 

The following link shows the infineon web page and the information of the low level driver for the MOTIX Microntroller. 
Low Level Driver - Infineon Technologies
There the following sentence is written:
The free package contains the source code, the documentation, the API documentation and release notes.

I got the source code from the config wizard for MOTIX. Also the release notes can be seen in this application.  
So my question is where can I find the documentation and the API documentation for the free MOTIX Low level driver 

Thanks, 

Stefan

 Hi,

What are the requirements for power supply (VDH) ramp-up? Unfortunately, I didn't find such either in the Users Manual or in the devices's data sheets. 

I noticed a different behavior depending on the VDH ramp-up. Under slowly increasing voltage seems that some of the microcontroller's modules are not reset properly, because they do not work as expected, the BDRV for example, or LIN.

Are there any reference designs for Reset Pin, that may help the device to start up properly on a slowly increased VDH?

The TLE9853QX is configured in bi-directional design similar to the evaluation board.

My question is about repeatability, accuracy, of the CSA value after gain at ADC1_OUT_CH13. 

I have the PCB assemblies configured in a controlled environment where I can generate a fixed load current while operating the processor in Debug. I recorded A2D values while setting the load at fixed current values. I record the values in 5 Amp increments from 75 Amps to 165 Amps. The hand written values attached were recorded. I then repeated the test an hour later and all the values are 5% higher. What accuracy can be achieved? 

Will the TLE9853QX always generate the same A2D value at ADC1_OUT_CH13 on a particular TLE9853QX every time the same input value is applied in the same environmental conditions? Or, will the A2D value at ADC1_OUT_CH13 always fluctuate within the tolerances of the part each time?

I have not been able to achieve any A2D values close to the calculated values in the attached document.

In Config Wizard Channel 13  (CSA) is Calibration enabled. See attached.

Table 80 in the TLE9853QX data sheet list a 5% tolerance for differential gain, uncalibrated.

Enabling calibration in Config wizard leads me to Table 57 in the TLE9853QX data sheet. Are these tolerances listed for the values read at OP1 and OP2 or the ADC1_OUT_CH13?

Table 57 in the TLE9853QX data sheet values are for a gain of 40. Are the values the same when using a gain of 60?

I have attached a partial schematic of the current sense circuit for reference. Shunt is 1%, 200uOhms. 

Please provide any guidance possible guidance. I am only using the differential amplifier to protect the design from over current in the application and I need to know how to properly use the feature.

Hi All,

Is it possible to control one or two outputs only? For example, let's say I would like to turn on GL1 only. What shall be the CCU6 configuration then? 

Judging by the existence of all bits LSx_ON and HSx_ON on BDRV->CTRL1/2, it shall be possible. But no matter how hard I tried, I didn't succeed. 🙄

Thanks to all in advance,

The question description of IAR software to develop TLE9879 chip

Question：
When I use IAR software to import Infineon pack, l find that the pack of Infineon can not be imported, please tell me which kind of Infineon pack l should to import to develop TLE9879.if you can give me an example, l will very appreciate you.

IAR version：8.32.1

In IAR software Release Notes，l check the device support，ensure that 8.32 version support TLE9879.

Infineon pack ：Version 1.6.0(2022-12-22) and Version 1.5.2 can not import success.
