Part Number: DS91M040
Hi,
One of our customer is using MLVDS buffer DS91M040 for backplane clock applications (ATCA compatible). Now when line card having DS91 is not powered then will there be any issue even if backplane clock is coming to this IC while it is not powered up? Will the internal ESD diodes will be creating any issues if the Input Signal is available but not the Power supply to this device? Please clarify.

Hi Team,
Could you tell me about the /BATDRV pin?
Data sheet describes the following.
”It goes 10 V below VSYS to fully turn on BATFET.”
Please tell me the reason why it is listed as 10V.
I think that it depends on the characteristics of use Pch FET.
Best Regards,
Yusuke
Part Number: BQ76200
Questions on the sheet titled FETs from the TIDA-00792 48V battery with gauge and high side switching reference design :
1) What does the symbol E1 denote?
2) What is the use of the diode D2, D3, D4? Doesn't the BQ76200 already have zeners inside?
Thanks
Part Number: LAUNCHXL-CC1352P
Tool/software: Code Composer Studio
Hi, I'm using LAUNCHXL-CC1352P-2 with BLE projects.
Recently, I need to use TRNG with the TRNG_RETURN_BEHAVIOR_POLLING behavior.
So, I tried to use TRNG like below:
static void SimpleCentral_taskFxn(uintptr_t a0, uintptr_t a1)
{
// Initialize application
SimpleCentral_init();
// Init the TRNG driver
TRNG_Params params;
TRNG_init();
TRNG_Params_init(¶ms);
params.returnBehavior = TRNG_RETURN_BEHAVIOR_POLLING;
// Open the TRNG driver to get the handle
TRNG_Handle trngHandle = TRNG_open(1, ¶ms);
if(NULL == trngHandle)
{
Display_printf(dispHandle, SC_ROW_CUR_CONN, 0, "TRNG FAILED!!!!!!!");
return;
}
...
}As far as I know, ble stack use TRNG with index 0, therefore I tried to use TRNG with index 1.
But, TRNG_open function always returns NULL.
How can I use this?
Best regards,
Inseob

Hi everyone,
i'm using the C2000 Launchpad XL to receive and transmit messages via CAN.
The problem i'm facing is the possible message ID's. I set up message boxes as follows;
CAN_setupMessageObject(CANB_BASE, CO_MSG_OBJ_ID_RX_TPDO1, CO_COB_ID_TPDO1,
CAN_MSG_FRAME_STD, CAN_MSG_OBJ_TYPE_RX, CO_COB_ID_T_MASK,
CAN_MSG_OBJ_RX_INT_ENABLE | CAN_MSG_OBJ_USE_ID_FILTER,
CO_MSG_DATA_LENGTH_TPDO);
Note:
* CO_MSG_OBJ_ID_RX_TPDO1 = 21
* CO_COB_ID_TPDO1 = 0x180
* CO_COB_ID_T_MASK = 0xF80
And i can get messages from different nodes 0x181, 0x182, 0x183...
But when i read the coming data with function, I only know object ID (21, 22, 23 etc.). I can not get message id.
I'm using C2000 Ware drivelib. How can i find which message id (node id) came?

hi,
we need support in PMP40441 software (we purchased it from TI direct through our US client),
Part Number: AM4372
Which compilers and debuggers can be used for the development of AM4372/6
Where to buy
Part Number: UCC28180
Dear team,
Colleague is using our UCC28180 as PFC controller, 220V AC input, 380V output, 1kW output power.
Can you help double-check the schematic and PCB design?
Thank you and best regards
Yunjing.
Part Number: TPS74401
Hi, team.
It will oscillate when sensing from the A point attached with TPS744.
It does not oscillate when sensing from point B or point C.
I want to remotely sense from point A because the IR drop is large.
Since an IC cannot be placed between the connector and the load, I think that it will not oscillate if the LDO has a slow response.
Are there 3A and 1A LDOs that support remote sensing and have a slow response speed?
Part Number: DP83822I
Hi team,
My customer used DP83822I design the board and the controlled is ST MCU. They wan't let ST communicate with PC by PHY.
But now DP83822I can't connect the PC and we read the (0x0001 Register) and found Link Status still 0.
BTW, SMI interface is ok because we read and write Register nomarlly.
Do you have any suggestions? Below is the SCH.
Part Number: MSP430F5524
The code running on my MSP430F5524 isn't responding to external inputs(such as a keypad) atter running for a short while. On certain occasions the code is able to enter the ISR(Timer, UART).
On putting the programmer, I am unable to pause the code. I am getting the message "Break at address "0xd00c4" with no debug information available, or outside of program code".
Any idea why this is happening and how can I resolve this? Could the code be getting into a "bad state" because of not handling an interrupt/doing an illegal operation like dividing by 0?
However, in case of not handling an interrupt the code should enter the "default" ISR provided by TI and enter into a LPM Mode( I have forgotten the exact name of this).
We are in a critical stage of our project. Any help would be appreciated.
Thanks and Regards

Hi,
I would like to add more PA TX power option for testing. like -1dbm. from smartrf studio, there is no any option for -1dbm to -3dbm.
Please let me know what this the TX power setting value for the above options.
As well as the lib we can modify to support the settings.
Thanks and Regards

Part Number: ADS8638
Hi,
There is an issue about the accuracy of ADS8638. The failure percentage is 40%.
Input : DC 5V from power supply to AIN0-7 => Output value 0-7: 5.012V
Input : DC 0V from power supply to AIN0-7 => Output value 0-7: 12mV
Is this related to input offset voltage ? Is it any possible to improve this issue by software or hardward ?

Part Number: TPS797
Hi,
We are considering to use TPS797, or more specifically TPS79733. One of its tasks would then be to act as reference voltage for some ADC measurements. Therefore we would like to ensure that we understand the accuracy details correctly.
1. The datasheet states an output voltage accuracy of +/- 4%. Is the expected behavior that each LDO unit typically ends up at a static offset from 3.3V within this 4% range, so that one could calibrate away the offset once for each board after building? Or could/will the output voltage for an inidividual LDO vary within that range from time to time so that the (unloaded) output voltage one time could be for instance +1% and another time -1%?
2. The load regulation is stated as 5% in amperes. Should the unit volts, or how should the value be interpreted?
Thanks!

I calculated Chem ID through the calculation tool of TI, and the results are as follows:
The best Chem ID is 217, but I can not find it in bqstudio. And I want to confirm whether ID 0217 is the same as ID217.
Can someone help me solve this problem?
Thank you very much!

Part Number: TAS5414C-Q1
Hi team,
We have made a board with B version DKD package in the past.
This time I will try to make a board again using TAS5414, but the C version has been released.
And C version doesn't have DKD package.
What is the difference between B and C?
Looking at the data sheets, there is no difference except that the ESD HBM is 2500V.
What is the reason why the DKD package disappeared?
Best regards,
Tomoaki Yoshida
Hi expert,
I need your help to selecting an AUX power controller or flyback IC for my customer. Better have TI design for them.
1. VAC input = 480Vac or VDC input = 400~1000V，V output =12V*4A = 48W
2. Stable frequency= 65kHz, have burst mode in light load condition
3. brown out protection function, pin protection.
Thanks
Sheldon
