I see many complains about Hall mode misoperation. I guess, at least part of that problems is due to the missing decoupling capacitor at VDDEXT pin. According to the TLE9879QXA40 data sheet, the capacitor 1..2.2uF is mandatory to ensure a proper 5V external voltage regulator functionality. This voltage is used to power Hall sensors.

Hello, 
This question has been already asked, but since there is no answer, creating new thread.

I am running a bldc motor Infineon TLE9879 chip. Now I want to measure the current flowing through the motor. so I use the current sense amplifier where the motor current is converted to a voltage by means of a shunt resistor RSH(0.005 ohms).
Question: I want to measure current for the lowside which gives the voltage drop at RSH.
I have calculated the offset in SW mode with gain 60 ensuring that MOSFET bridge is off(0 current flowing). After that, I switch back to SQ mode and check for ADC value in Ch1. It always shows a constant number when the CSA gain is set to 60, when the motor is running at any speeds. We tried to measure the voltage levels across OP1,OP2 which are nearly 0.

Please suggest the configuration for Current sense.

Hi everyone, 

We are working with a BLDC motor (see attached below) and the BLDC shield TLE9879. We are using the Hall sensors. 

When can spin the motor fine in one direction (low current consumption) but in the other direction current consumption is too high (we've tested with no load and load on motor). We also found a phase (U, V, W) configuration where when we switch cables for Hall sensors the problem reverses (the direction that had low current consumption has high consumption and direction that had high consumption has low consumption). 

We've tried playing with the parameters of the board (delay angle and HALL_INPUT_A/B/C) but we haven't seen any improvement during operation. 

Does anyone have an explanation for this problem? Is it possible the board doesn't support bi-directional control (there is nothing about this in board documentation)?

Also, is it possible to get a clear explanation of the different parameters for the BLDC Shield?

Kind regards

Hi，

请问以下三个型号的TLE9877有什么区别？该如何选型？

另外，BF和UH代表什么呢？谢谢

Hello ,

When we installed Config Wizard for MOTIX MCU, the Config Wizard option in Tools menu of Keil was not automatically added.
We had to configure it in the Customize Tools menu options explicitly:

As per the Getting started guide the Config Wizard should automatically be added in Tools once all settings are done.

Also for some members(different location) the procedure worked as expected.
Why did it need configuration on my Keil?

I just bought a TLE9879 Evalkit to evaluate BLDC motor control. And I want use J-scope to monitor the variables of FOC demo. I download the j-link V7.82, but the j-scope didn't work.  Is my Evalkit onboard XMC j-link inmatch with the j-link driver or something else wrong?

I use the Mode 2 command when programming, and the  programming   range is 0x11000000-0x1101FFFF.

 

And I originally wanted to program all the addresses at once, so I first sent the Header Block and set the Block Length to 0x82, then sent the Data Block in sequence, and finally sent the EOT Block, but after sending the EOT Block, the IC will reply me 0xFF.

However, the commands before the EOT Block are very normal and reply me 0x55. 

Why is the IC replying 0xFF after sending the EOT Block after I program all the addresses of the Flash?

 

So the way I can normally program at present is to send the Header Block and set the Block Length to 0x83, then send the EOT Block and include the data of a page, and then repeatedly send the Header Block and the EOT Block containing the data of the next page until the last page programming is completed.

 

Although it can be programmed normally at present, I still wonder why the first programming method fails.
