Part Number:TMS320F280041
Tool/software: Code Composer Studio
Dear Mr./Mrs.,
I am from China. Now we use TMS320F280041 for one project.
For using its EPWM trip-zone function, we config it to one-shot trip event and know the trip-zone signals TZ1 to TZ6 (also collectively referred to as TZn) are active low input signals in the datasheet, but we want to use falling edge instead of low level for triggering TZ .
Could you tell us how can implement this?
Thanks a lot!
Best regards!

We are using Peak CAN adapter it takes 28 minutes for BANK 1 size 1.5MB download including delays , we do not have an idea of how much time is taken for Erasing and writing one Sector with NI CAN .
It would help us if we know how much time is taken for one sector using NI CAN and TI provided Boot loader.
It will help To have a Comparison between NI CAN adapter and PEAK CAN adapter and to optimize the code .
Part Number:UCC28780
Hi,
I am currently working on a Active Clamp DC-DC Flyback Converter based on UCC28780 and UCC27712. If I succeed we will use this topology and components in various designs. But I am struggling. When I power up the circuit, Vdd starts to go up and down between 10V and 18V. Meanwhile PWML sends a single pulse, waits a while (maybe 1 second) then sends another single pulse. What am I missing here? I have calculated all the components according to the equatins which are in the UCC28780 datasheet. Please help me out.
Here are the parameters:
Vin is in between 30V and 60V.
Vaux:15V, Vout1:36V, Vout2:18V, Vout3,Vout4 and Vout5:15V
Best Regards.
Part Number:CC2541
Hi all, I am the new for design the blue tooth RF product, when I design the dipole antenna to use on my product with cc2541, did I still need balun circuit?
1 pole for output and 1 pole for gound mirror? or directly connected with RF_P and RF_N by 2 poles? any related design can share for my reference?
thanks!

Hi,
I tried to download the DLMS/COSEM MSP430 library, but the link is not working:
http://www.ti.com/tool/DLMSOBJ-EVAL
How can I find the correct link? Is it possible?

Part Number:BQ4802Y
Why the BQ4802Y Clock is not keep clocking when system power down ?
I have setted /STOP=1 in cotrol register E and use CR2302 Li Battery for Vbc. but the clock is not continue clock while system power down.
I've checked the BVF flag in flags register D. The BVF is 1.
I need somebody to help me solve the problem.

Part Number:TUSB422
Hi team,
According to the datasheet, the only difference between PD3.0 and TUSB422 specification is PD 3.0 Get Source Capabilities Extended Message. Is that correct? Are there any differences with PD3.0 specification and TUSB422 specification?
If possible, could you explain the reason why TUSB422 can't support "PD 3.0 Get Source Capabilities Extended Message"?

Part Number:SN75DP130
Hello
The topology is NB-> typec connector -> Mux -> DP130 -> Monitor. If NB output four lane DP, the monitor will be light up normally. But if NB output two lane or one lane DP, monitor fail to light via DP130.
After bypass DP130, Customer use Google NB output 2 lane and 1 lane DP, the monitor will light up normally. If use Astro VG-870 (DP to Type C cable Pin assignment E), the monitor still light up normally.
Why two lane and one lane not light up monitor via DP130? Thank you.
Google NB(Chrome book)
1366x768@60Hz
Astro VG-870 (DP to Type C cable Pin assignment E)
800x600@75Hz(HBR 1 lane)

Hi team,
My customer is considering to use the device with TIDA-01582 reference design.
Could you tell me what the revision and the version TUSB422 is supporting?

Part Number:TPS54620
Tool/software: WEBENCH® Design Tools
In my project,I used TPS54620,And in unit test,I found that ,the startup ware form increases with the oscillatory behavior(I have seen this problem in WEBENCH simulation too).
parameters of my design :
Vin = 10~14V;Vout = 1.1V;Iout = 6A
How to avoid this,and why?
Part Number:TMS320F28027
Tool/software: Code Composer Studio
When using chip 320F28027 serial port online upgrade, set GPIO37 low and GPIO34 high.
Restart the chip and send the hex file to the chip via GPIO28 and GPIO29 via the serial port tool.
The serial port tool will receive the same data stream as the sent data.
Restart the chip again. The sent program did not update successfully.Online updates look like a postback mode。
why？
Part Number:PCA9518
Hi TI team,
We are using the PCA9518 with TI translator (TXS0101, 3.3V to 1.8V) to access the PCIe switch through Micro-controller in our board and PCIe switch needs clock stretching support. When PCIe switch does clock stretching, then a glitch happens on I2C bus with TI I2C expander which causes the wrong access to PCIe switch. if we use the PCA9518A from NXP, then we do not see any glitches and no errors on I2C bus.
As per latest PCA9518 datasheet, PCA9518 does not support clock stretching and having issues with high rise accelerators.
Does TI have any plan to fix this errata for the PCA9518?
Does TI have an footprint compatible part (with PCA9518) that does not have this errata?

Part Number:TUSB4041I
Our customer asked a question. When an individually port-power-controlled hub senses an overcurrent event (OVERCURz asserted), the hub reports the port's overcurrent event to the USB host and then the host sends Set_Feature(?) to switch off its downstream port's VBUS. When this happens, what is the D+ and D- pins state? H-Z state?
