Part Number:TPS25942A
Hi,
Could you please tell me the recommended schematic if using a couple of TPS25942As as the constant current source(the current limit : ~10A) when the large current such as 10A flows to the load ?
Please provide me the material as the following post.

Hi,
I am trying to build eve sw.
When i build eve sw, the procedure display build fail log as blow.
I just modified the makefile of eve sw.
I can't fine "algframework.h" file in the "C:\PROCESSOR_SDK_VISION_03_00_00_00\ti_components\algorithms\eve_sw_01_16_00_00\kernels\imgsiglib\BlockAverage2x2\inc".
How can i fix the build fail ?
Thanks.

Part Number:RF430CL330H
To whom it may concern,
I am Binh, Now I am using RF430CL330HTB controlled by a MSP430 MCU to read data from some sensors, so I want to ask you about the problem that I am confusing, could you please let me know:
1) Did TI make any measurement about the power received from a NFC-enabled smartphone using the on-board antenna of the RF430CL330HTB. Because I would like to know whether it is enough to drive the MCU and sensors whose total power consumption is approximately 3 mW.
2) If I want to use external antenna for this board, does TI provide any reference for consumers to determine the appropriate antenna geometry? Thank you so much.
Sincerely,
Binh Nguyen Thanh
Part Number:OPA244
Hi all
Would you mind if we ask some opamps?
About below amps, which amps are JFET or bipolar type?
We are sorry that we could not judge correctly.
As our recognition, it seems that OPA244 and TLV2451 are bipolar type because of low bias current.
-TLV2381
-OPA347
-TLV2451
-OPA348(OPA348-Q1)
-OPA244
Kind regards,
Hirotaka Matsumoto
Part Number:TPS730
Hi,
The block dig arm of TPS730 has one 59K pull down at the output. is it for discharging the output voltage when LDO is disabled?
Can I test this resistor value as per below procedure.
1. Put LDO to shutdown more (EN=0)
2. Force voltage to output and measure current and calculate the resistance from this value.
Regards

Part Number:CC2640R2F
Hello All,
II am using CC2640R2F from scanning BLE tags and sending data to other MCU.
While testing, i have observed that CC2640R2F resetting after some interval.
I have removed power signals of CC2640R2F while testing, but still its working, only UART pins from other controller which is powered.
So MCU is getting powered from UART pins only, (power pins not connected to 3.3V supply)
So please guide in this regard.
Regards,
Sharad.
Part Number:SN65LVDT100
Hellow support team
I have two questions.
1. When restarting the SN65LVDT100, SN65LVDT101 and SN65LVELT23, how much required time from power OFF to power ON ?
My customers are considering operations at less than 1 ms.
2.When turning on the power after turning off the power (SN65LVDT100, SN65LVDT101 and SN65LVELT23), what voltage is required falling voltage?
The customer is considering lowering it to 1V.

Part Number:TDA2EXEVM
Hi,
I am using vision sdk version 2.12. And below is my usecase,
Capture -> Select -> VPE_HD -> Merge
Merge -> Encode -> IPCIn(A15) -> Nullsink (A15)
Select -> VPE_D1 -> Merge
One HD capture in "SYSTEM_CAPTURE_INST_VIP1_SLICE2_PORTA" and two CVBS capture in "SYSTEM_CAPTURE_INST_VIP1_SLICE1_PORTB".
The usecase is working fine with 3 channel capture. I enabled 2 more CVBS channels and it is giving the following error,
"[HOST] [IPU2 ] 64.176264 s: In VpsCore_vipPathCreateDesc() pathObj->numChannels = 1, pathObj->numStreams = 1
[HOST] [IPU2 ] 64.176477 s: 53071: Assertion @ Line: 1703 in hal/src/vpshal_vpdma.c: NULL != memPtr : failed !!!"
please suggest.

Part Number:MAX3221
Hi, im considering to use the max3221 for a project, but im a little confuse becaue i usually use not-shutdown power supply transnceivers and i didnt understand very well about UNVALID, EN, FORCEOFF, FORCEON, but as i understand the datasheet i did this diagram
i dont want to use the low power supply mode, i just want to use the disable power down mode, and in the datasheet says that if you put the forceon and forceoff to vcc it will be disable and EN to ground ROUT wil get a low impedance(that comunciation will be posible i guess)
so i want know that if this is correct to a comunication with a rs232 and uart port? also i want to add that my pcb only have a 5v power supply voltage, and no a 3.3v voltage supply.
thx for anyhelp
Part Number:DS90UB953-Q1
Are there any same package with DS90UB953(32 pin VQFN)?
which device is the same package with DS90UB953(32 pin VQFN)?
DENSO will test the mounting reliability of DS90UB953, but they can't get the enough number of the device.
so they would like to substitute IC of the same package. Electric spec is not care.
Best regards

Part Number:TPS560200
Dear Specialists,
My customer is considering aluminum electrolytic capacitor for input and output capacitance.
If yes, could you please advise the range of ESR.
Recently the delivery of the ceramic capacitor became tight, so they are thinking of using electrolytic cap.
I appreciate your great help.

Part Number:HDC1080
Dear Jose-san,
In the past, Fukasawa received Jose-san special support on the humidity accuracy of HDC 1080.
We are continuing QA with customers, but we have not solved it.
Please let me ask a question again.
<Situation>
An HDC 1080 is mounted on a mass production board of a customer.
This board is called a board A.
However, humidity accuracy errors occurred on some board A.
Therefore, exactly the same size as board A,
board B composed of the same parts was prepared.
The customer has identified the cause by comparing board A and board B.
※ Board size = 0.4 cm × 1.3 cm
Configuration = HDC 1080 + 1 capacitor only
However, an error of + 5% steadily occurs in the humidity accuracy
measured on the board B.
Also, as a result of allowing the board B to reflow again and then leaving it,
it was possible to confirm the result that the accuracy recovered.
(Reflow is recommended only once. Customer is known)
<Question>
① We don't understand why the difference between board A and B occurs although
both of their production conditions are same.
Could you list possible cause?
② If the reflow temperature is low, is there a possibility of an accuracy error of 5%?
Because accuracy restoration was confirmed when re-reflow was applied.
Best,Regars.

When visiting a free Wifi Hotspot, quite often a Wifi-Login page comes up automatically on my phone.
Do you have any Idea how I could tweak the internal DNS to do the same during provisioning?

Part Number:TPA3117D2
Hello
My client is currently working on a smart speaker with the TPA3117D2.
The current output is designed as Mono max 10W.
We will ask you to review the current circuit configuration.
(/ SD, PLIMIT, REG_OUT, FSEL, input, output pin)
Also, should / SD and FSEL be controlled by AP?
I will attach the circuit diagram and confirm it.
In my opinion, I need to reconfigure the output filter. Is there any relevant example?
(Please visit the site to view this file)
Part Number:CC1350STK
Hi,
noticed that the CC1350STK is very hard to come by overall nowadays, when looking at the common suppliers (Arrow, Mouser, Digikey, ...). Is it being phased out, or what are the plans if I may ask?
We commonly use the CC1350STK for demonstration and POC purposes in the early stages with customers, and as such the sub-GHz sensortag is an excellent platform. So, I'm hoping it will stay in business :) Perhaps there's a CC1352STK planned?
(I know it's possible to buy a handful of CC1350STK on ti.com, but when we'd like to buy more we often go via eg mouser).
Cheers,
Marcus
Part Number:TAS5751M
Dear Sirs,
My customer asked us about latency of TAS5751M.
He wants latency within a few milliseconds.
So I have the following questions.
1.How long is the delay time (latency) with no effect function (Through condition)?
2.How long is the delay of this function?
Of course I know that it will change with the number of BIEQ used.
Please let me know about above questions.
Best Regards,
Y.Hasebe
