Dear Infineon family,
Can someone please let me know how to check if TLE9879QXA40 chip is good?
I have three boards based on TLE9879 (bldc arduino shield) with me in which when I connect the first two to the 15V power supply I am getting a power consumption of 250mW however in third one the power consumption is only 5mW.
In datasheet it is mentioned that the device sleep current is in range of uAmps, if that is the case then is third chip in sleep mode?
Show LessI have tried to replicate TLE9879QXA40_BLDC_BEMF example program for TLE9893 BEMF IMPLEMENTATION but interrupt is not enabled in TLE9893 BEMF IMPLEMENTATION code
Please give me solution for above interrupt issue if you want code the I will share you.

After following the procedure to port the code for new device we are facing a new problem.
The Program runs fine in Debug mode, but in Release/Run mode the program doesnt operate as expected.
Its difficult to analyse the issue as in Debug mode it runs totally fine.
When we run without debug, as we could observe the code is running as per our commands, some states in code are viewed on LIN. But the BDRV is not operational, means we dont see any output from the driver unit to motor.
What could possibly go wrong? any hints to debug the issue?
update:
Some times even in Debug mode (very rarely) the program got stuck.
I collected some snapshots of register status when the program was not running correctly
We need to fetch two signals from ADC channels; one is from External ADC input channel and second is Bridge Current which should depend on the PWM duty cycle. Could you please help us configure the ADC for both signals. We used the "BDRV_EMO_DC_LIN_EXAMPLE_TLE986X" package as our base.
Show LessI'm currently trying to use a development board to drive a sensorless brushless DC motor (BLDC), requiring the use of reverse EMF to determine the motor rotor position. Are there any demos or tutorials related to the TLE9893 series of chips?

Show Less目前我正试图用开发板驱动一个无传感器类型的无刷直流电机(BLDC),要求使用反电动势法确定电机转子位置。有没有TLE9893系列芯片相关的的DEMO或者教程呢?
TLE987x系列的电机库的使用中有几个问题请教。
1,如何获得相匹配的demo板?最好是风机类的。
2,
Ifx FOC oneMatchCallback是通过重定义得来的
而CCU6_T12_OM_CALLBACK是在CCU6SR1_IRQHandler中断服务函数中调用?
CCU6SR1_IRQHandler是timer中断。
我的以上理解对吗?
3,真正的FOC计算是在Ifx_FOC_oneMatchCallback这个函数中,我这个理解对吗?
4,下图99,100行这里是在CCU6SR1_IRQHandler中再次触发PendSV?如果是这样的话,为什么要操作内核中断PendSV?而不是直接在CCU6SR1_IRQHandler中完成foc的计算?
5,电流采样部分是单电阻采样?有没有双电阻采样的代码?
6,我的以上疑问在下面这个文档里是否有说明?可能是篇幅原因,找了几遍没找到。另外,我看到文档里是用的id,iq表示。但代码里是用real,imag?
以上,谢谢。
