MOTIX™ MCU Forum Discussions

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.

Hi, 

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

Hi

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

Hello, everyone.

TLE9879_EvalKit development board comes with the program, if in the initialization, add a long time delay, such as more than 2s, the system can not work properly.

A delay of 1s is normal. I don't know where the conflict is, please advise.

int main(void)
{
/* Initialization of hardware modules based on Config Wizard configuration */
TLE_Init();
Delay_us(1000000);
Delay_us(1000000).
TIMER2_Start();

for (;;)
{
(void)WDT1_Service();
}
}

Hey,

I'm writing to discuss an issue I'm encountering with the TLE9879QXA40 controller for sensorless FOC motor control. Specifically, I'm having trouble reading the MCU internal temperature accurately.

To provide some context, I conducted tests with the MCU operating at room temperature (40°C). Under normal conditions, with the motor running at 12V, the total current drawn by both the MCU and the motor amounts to 2.5A, resulting in a power consumption of 30W, and the MCU temperature stabilizes around 54°C.

However, when I increase the applied voltage to 17.5V, while the total power consumption remains approximately the same (30W), with the system drawing 1.3A, and the MCU temperature stabilizes around 59°C.

I'm noticing a puzzling increase in MCU temperature by 5°C.

This discrepancy is perplexing, as the total power of the system remains constant. I'm reaching out to seek clarification on why this temperature elevation is occurring under these conditions.

Your insights and assistance in resolving this matter would be greatly appreciated.

Best Regards,
