Hello 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.
你好!
在NORMAL状态下,我用WriteRow写NAR时报0xF00000AA(Writes are disabled in safety register)错误,
请问是什么原因?另外,可否提供使用WriteRow的例程?谢谢!
补充一点:这部分代码我是放在CM4里的,这可以吗?
Show LessTi gave a link to Cypress telling to download the driver, the link is as follows
https://community.cypress.com/docs/DOC-12366 but the link says it's archived and can't be downloaded
The normal FX 3 driver won't work again, can you share this driver with me?

Show LessHi, I am using the ICE2HS01G in a high voltage application.
Sometimes, the IC does not go into burst mode and keeps switching continuously even with the LOAD pin pulled down to ~0V by the feedback control based on the TL431 IC.
Is this a reported issue with noise, perhaps on the Vsense line?
Thanks,
SS1
Show LessHello,
I am looking for the Firmware project (Eclipse Project) for the OV7251 Image Sensor. Even a simple implementation that offers the following functionalities will be sufficient:
- UVC-compliant output
- 640x480 pixel resolution
- Raw video
Does anyone have a project that can be shared?
Thanks in advance,
Mo
Show LessHi,
I am programming the IR35204 Chip.
Loop1 Vout is successfully shown our setting.
But Loop2 Vout has a low level and looks like a noise.
is there a any solution about Loop2 Operation successfully?
Please Let me know
Thank you for your help
Show LessHi,
I want to translate the following article to Japanese. Please confirm to my work.
