Hi Sir,
想請問6EDL7141 OCP 與current amplifier 的位置關係
datasheet 的方塊圖OCP是在current amplifier之前
application note的方塊圖 OCP在current amplifier之後
請問何者是正確的呢?
謝謝!

Dear Infineon support team,
Development environment
OS: Windows 10 pro
Compiler: ARMCC V5.06 update 6 (build 750)
Tool: Keil v5
Device: TLE9879QXA40
Board: Custom
Motor: IPM BLDC Delta connection
Power spec. : DC 12[V] 80[A]
With the off-state diagnosis function, I want to diagnose before starting the main statement, and after starting the main statement, I want to turn off the off-state diagnosis function and ignore DS-sts.
The user manual also states to disable DS-current and ignore the DS-sts flag.
However, it is not explained how to ignore DS-STS.
Because of DS-STS, the PWM_EN function continues to be automatically turned off.
How can I ignore DS-STS and make PWM_EN function work?
Show LessHello everyone! I have some questions about tle9879 driver bldc, pwm frequency selection, and would like to get answers.
For the same motor, the motor inductance parameter is measured and the results are measured:
Frequency 1khz ------Ls-900uH Lr-0.8Ω
Frequency 10khz ------Ls-880uH Lr-5.4Ω
Frequency 15khz ------Ls-850uH Lr-10.2Ω
Frequency 20khz ------Ls-830uH Lr-16.1Ω
If you look at it according to impedance, the lower the frequency, the lower the impedance, then the greater the output capability of the motor; conversely, if the frequency is high and the impedance is high, then the output capability will be reduced.
But the actual test to see, the results are not so, ccu6- >T12 is also on the pwm setting frequency 10hkz when the carry capacity is very weak, a little bit of load may be held back; and 20khz than 10khz carry capacity is much stronger. Here may have something to do with the renewal current, but exactly what is not understand.
Anyone who understands the relationship between frequency and torque would be grateful for an answer!

Show LessDear team I need to wakeup MCU once its go below 3V, using LIN wakeup, if any sample code/ or configuration is available please let us know.
大家好 请问有没有关于TLE9879的CSA例程,BLDC电机控制里想加一个电流检测,官方例程里没有关于CSA的例子,希望有使用过这个功能的分享一下经验。 谢谢!
Hello,
I'm buying the TLE9879 from Digikey, do they come with pre-programmed BLDC Driver? (same as the one on the Arduino shield).
If not, where can I order pre-programmed chip?
Thanks in advance.
Best,
Thai.
Show LessHi,
I am using a malloc and calloc functionality for a DAQ implementation purpose. I am using TLE9893 series chip . the code compile well but seems to stuck while in debug mode on calloc and malloc function. I tried to set heap size to 16K but didnt work. Any suggestions/alternative method of using this. !!
I am not looking for any optimistic memory allocation, just need a basic memory allocation method.
Thanks
Prakash
Show LessHi,
I am trying to implement a RTC timestamp in the TLE9893 series. Can you give us a idea or example source project for a basic RTC example
Thanks

Show LessHi
One of my client is looking for flush door handle to drive 12V/1A motor with minimal circuitry using full bridge topology & required inbuilt LDO / LIN Communication & if mosfet inbuilt will be better.
I have chosen TLE9853QX + IPG20N04S4-18A to support here. Any other recommendation let me know.
Regards
Lucky Kumar
