Part Number:TPS54232

Dears:

From datasheet I can see the power input is from 3.5V to 28V.

But I can not simulate design based on power input is from 3.8V to 24V and output is 3.3V using Webench.

Why can not set the lower than 4V about input?

Pls. kindly help to give some advice.

Part Number:DAC80508

Does the \CLR pin behavior (i.e. set all outputs to zero-scale level) require any part configuration or does it take effect immediately after power on? If we hold \CLR low at power on do all the outputs come up at zero-scale or are some SPI transactions required before the outputs reset to zero-scale? Appreciate your help - thanks.

Part Number:DS90UB936-Q1

Hi,

    I used DS90ub936 with sensor ds90ub933 input port0,only set ds90ub936 0x33(0x01)  enable CSI output, then test DS90ub936 Lock Pin is High,but CSICLK no output clock,always is high voltage

whether need to set other more registers?

      the DS90ub936 Mode pin set to RX mode RAW10

Part Number:TM4C1290NCPDT

Hi all

I have a custom board with a TM4C1290NCPDT microcontroller. After loading my second program (the LED blinking worked) I tried to load a UART testing program, which required me to set the system clock. Though the board does not have an external oscillator, I set the code as follows:

  //
  // Set the clocking to run directly from the crystal at 120MHz.
  //
  g_ui32SysClock = MAP_SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ |
					   SYSCTL_OSC_MAIN |
					   SYSCTL_USE_PLL |
					   SYSCTL_CFG_VCO_480), 120000000);

Since that time the board no longer appears to JTAG ("failed to connect") and I'm assuming that the clock setting above is to blame.

I've tried the LMU programmer erase via an ICDI launchpad (TM4C123GXL eval board) with out luck.

Any suggestions on how to recover the board?

Thanks

Peter

However, the board does not have an external oscillator (oops) and now I can no longer load the board 

Part Number:EK-TM4C1294XL

We are developing a product with firmware based on the reference design enet_s2e example.

I wanted to add and remove item from the left menu but when I do the daughter pages do not load correctly.
I tried removing the CSS sheet since I thought that might be part of the problem but problem remains even with out any stile sheet.

I can duplicate the problem in the example project with a single modification to the file index.htm in the FS folder.

I commented out the line in the list for config2.shtm. Screen shot to follow.

Once I comment out the line, save the file and refresh the web page the navigation to the link misc.shtm malfunctions. Normally you select the link and the contents of the file misc.shtm is opened in addition to the index.htm. But after the change the link loads the misc.shtm file completly replacing the index.htm. .  Screen shot (with out cascaded style sheet function) to follow.

Part Number:OPT3101EVM

Hello,

I am trying to install the drivers for my OPT3101 but encounter the following problem (see picture below).

I also added the picture of the OPT3101 if that helps.

The control and data remain under other devices in device manager.

I followed the manual installation as in the guide.

And it's the latest GUI software.

How can I solve this?

Kind regards,

Scott

Part Number:TM4C129DNCPDT

Hello everyone,

For a required spec in our project, the clock on our processor (Tiva TM4C129DNCPDT) must be very accurate, within 10 milliseconds of the UTC, and must be re-synchronized periodically. Because we must also have the RTC running while powered down, I'm using the Hibernation Module's RTC (the module runs off our battery while not powered).

I need to be able to set the sub-second value in the Hibernation module in order to achieve the required accuracy, but the register appears to be read-only. I've even tried writing 0x00000000 to reset the register, but that doesn't seem to work either. I'm also following the steps that are used when calling HibernateRTCSet, locking and unlocking, and waiting for each write to complete.

Is there any way at all to set the sub-second value? Or do I have to go about getting this accuracy some other way? The main alternative I can think of is applying a sub-second offset to all of my timestamps, getting this offset while synchronizing. But it would be easier just to have control over this register.

Thanks,

- Tom

Is this the correct package dimension drawing for the DKD 36 pin package?  There are no dimensions on this document it is just a picture of the part.  Am I missing something here?  I was looking for a drawing specifying mechanical dimensions for this part.  This information is not in the part's datasheet either.

Part Number:TPS65917-Q1

Hi,

     Customer want to find a PMIC for AMBA CV22/CV25 platform, the competitor are DA9063 and DA9062.

I suggest they choose TPS65197-Q1 ,but in other e2e thread mentioned  the power sequence can't modify through i2c/spi by MCU.

So I want to know how can I found power sequence plot of each OTP revision , I didn't found in datasheet. Is it just for TI  platform like TDA/DRA/?

Or could you suggest me another PMIC part number ?

Customer need 4 channel buck (one of the four channel need 0.75V/5A rating, another  less then 1A) and 4 channel ldo.

Thanks

Part Number:TPS23523

A previous post tells that in the choice of the O-ring FET.

The OR-ing FET selection is based on the Ron of the FET.
The TPS23523 device will regulate the forward drop across the OR-ing FET to 25 mV. So, the selected FET should have Ron to result 25mV drop across the FET for proper regulation while delivering nominal load current.
For example for 10A load, FET Ron should be 2.5mOhm

But TPS23523 EVM is using 2x BSC320N20NS3GATMA1 FET, with a max 32mOhms rdson, so divide by 2 FET it's 16mOhms.  with a current load at 12.5A, this mean 200mv drop and not 25mV.

We are wondering where the 25 mV specification comes from. Is it an arbitrary value set by internal voltage references or does it come from somewhere else ?

What happens if the condition is not respected (i.e. 200mV drop like the EVM?) ?

Does it cause damage to the IC ?

What is the impact of not having 25mV drop?

In fact we are still trying to understand what the IC does to regulate the 25mV and why...

Thanks

I have a HWI that is linked to GPIO 12...inside the ISR, I trigger the DMA for PCIe transfer...everything been working great so far. We added a gps module to the spi interface and we noticed that if SPI is active (polling the gps data every second), the HWI doesn't run...my understanding is that the HWI is higher priority...how is the SPI priority related to the HWI priority.

My system interrupts are shown in the attached document

Part Number:MSP432P401V

Tool/software: Code Composer Studio

Good evening,

I am currently trying to reproduce the datasheet specifications for above MCUs. While successful with the 401R variant, I did not suceed with the 401V one.

I am using the MSP-EXP432P401R and a custom board for the 401V.

The following code goes to LPM3 with RTC sourced by LFXT, and enters LPM3.5 on RTC interrupt after 1 minute. On the 401R I measure 0.85 µA for the first minute, then 0.65 µA afterwards. But on the 401V its 1.3 µA at first (unexpected) and then 0.85 µA after transition to LMP3.5 (essentially as per datasheet). The datasheet states on page 44 a current drawn in LPM3 with RTC sourced by LFXT and VCORE0 of 0.82 µA, but I am not able to reach this value. Any suggestions?

For some reason it seems that the TI compiler isn't picking up the stdint.h header when building. This same process does work on another machine but not on this one. As you can see from the output, the linker is getting passed the correct directory as a parameter but is not finding the file.

Part Number:ADS8689

When performing an RSS of error terms, like it is outlined in the document: ADC Parameters Unit Conversion (SLAA587)

First question has to do with the fact that he Gain & Offset errors in the ADS8689 datasheet (min/typ/max) are at 25C. For a true TUE (Total Uncorrected Error) calculation using the RSS method - I assume that one can find the Min/Typ/Max TUE by using the corresponding values in the table. Correct?

The next part of the question is - I would like to find the TUE over temperature. What is the recommended method for doing so with this ADC?

Also for this ADC - since the System Performance numbers are using the internal VREF... I assume we leave the VREF (errors) out of the ADC RSS TUE calculation.

Basically - I would like to know how much TUE I have both at 25C, but also 'at temperature', to see if I can meet my specification targets without having to trim/calibrate the unit.

Thanks!
