SN75LVCP412: need a device with operating temp from -40 to 85
Part Number:SN75LVCP412
hi,
we have selected this for our design. but, after completing the PCB fabrication we came to know that it is operating from 0 to 85. Now, we want the same device for operating at -40 to 85.
or equivalent pin to pin compatible device.
please suggest as soon as possible.

UCC256304: OUTPUT Waveform
Part Number:UCC256304
Hello
I am evaluating using UCC 256304.
Because I want to correspond with 100 V input, because EVM can not be used, I am coping with changing parts of EVM. (Transformers, change the devices around)
When I changed parts and evaluated it became the waveform as attached.
It looks like a switch that looks like a switch, but there is no output.
Circuit diagrams can be sent.
Please tell me the destination.
Thank you.(Please visit the site to view this file)

Part Number:BQ76PL455A-Q1
Hello,
OWD cannot occur during balancing? As this IC has external MOS to balance, all the cells will be balanced at a time ,then why the squeeze function occur only on alternate resistors ?
Thank you,

SN65HVD251: about building network for SN65HVD251
Part Number:SN65HVD251
hi dear supporting team,
for SN65HVD251, each one of it could support 110 nodes, now customer need support 250 CAN nodes, could they use below way to build the network?
the yellow portion is CAN repeater brd, there are two CAN circuits inside. using one MCU to do CAN communication internally and the CAN repeater with external, CAN transceiver are all SN65HVD251. there are 50 nodes in each repeater. totally 250 nodes. is it ok to do this way to enhance the CAN signal? tks a lot!

UCD3138: I don't know what init_pmbus(0x58) means
Part Number:UCD3138
Hello
I recently learned the firmware of UCD3138's 29th full-bridge hard switch development board.
I read the subfunction init_pmbus(0x58) in the void main() function.
The firmware told me that 0x58 is a pmbus_address, but I don't know what pmbus_address is, what data I should learn, or where pmbus_address is defined in the firmware. I don't know what 0x58 means. Maybe there are other address numbers?
Thank you

Gate Drivers for Solar Inverter Application
Hi.
I hope someone can answer my queries regarding my 3.5kW grid -tied dual stage solar inverter design. Currently, I am using IGBTs and ISO5000 for isolated gate driver supplies. I want to know what is the best gate drive supply.
Firstly, GaN FET are starting to replace silicon based IGBTs and MOSFETS. Also, you have suggested a possibility of using GaN FET in solar inverter application in the blog "Rethink your solar inverter with GaN". So, should I replace IGBTs with GaN FETs. If so, what would be the gate drive solution for GaN FETs.
If I continue using IGBTs (switching frequency is 15-20kHz), is ISO5500 good or would you recommend some other gate drive solution.
There are plenty of options available on TI's website - for single channel,, dual channel and full-bridge gate drive supplies. Which one would be ideal to use. Can you please suggest with relevant reasons?
I would be grateful for your response and suggestions.

DAC8820: the question about the output of DAC8820
Part Number:DAC8820
I would like to ask how the DAC8820 outputs. When the DAC is converting the digital signal to an analog signal, what is the output of DAC8820EVM Evaluation Module? Is there an analog switch structure inside the chip?The DAC can output the voltage only when the the DAC has converted the digital signal to an analog signal.

RS232 WITH hydreon (rain gauge)
Hi all,(am a new user here,so if there is any mistake pls do tell)
anyone of you all know how to decipher this meaning?
"
Frames start with the transmission of an ASCII 's' character. Each data byte is then sent as ASCII-Hex over , meaning that the upper nibble of the byte is converted to a single ACII character, 0-9 or a-f. The lower nibble is then similarly transmitted. For example, if the data byte is a decimal value 108, this would be hex 6C. This is transmitted as an ASCII “6” followed by ACII “c”. (Yes, lower case is used.) There is no end-of-frame character. 's' Data Byte 0 upper nibble Data Byte 0 lower nibble Data Byte 1 upper nibble ... Data Byte 9 lower nibble
"
newbie here
if anyone could please kindly assist me ?? appreciate it alot & thanks a million!

Hi all,
I have a custom board with DM385 and I am running 2.6.37 kernel.
My problem is that the kernel doesn't detect the SD Card when its booting.
Following are the debug messages for MMC.
Could someone point me to which file to modify? or Is there a flowchart of kernel file chain that would show me which file/function linux kernel calls?

RTOS/TDA2P-ACD: Required hardware and software to run fusion example
Part Number:TDA2P-ACD
Tool/software:TI-RTOS
Dear Champs,
My customer would like to develop camera/radar fusion on TDA2Px. The wan to know the required h/w and s/w to run fusion example.
1. So far I know the required h/w are below. But what is the required radar module? I can not find the info for required radar module from both TI and SpectrumDigital's web site.
a. TDA2Px EVM x 1
b. Fusion Card/EVM x 1
c. TIDA OV2775 cameras (with Fakra cables) x 1
2. Is there any SDK that supports camera/radar "fusion" use case? If no, when will TI support this use case?
Thanks.

TM4C123GH6PM: Code Composer Studio Simple Codes using Tivaware

Hi. I have been working with the TM4C123GH6PM Microcontroller for the past three years. I'm a laboratory Instructor for San Carlos University in Guatemala and I have developed simple codes (tested) using TivaWare that anyone can use. I would like to share these with all here, as when I first started working with it, it was a little difficult to find material.
I even have some material in Spanish in case someone needs it.
Hola. He estado trabajando con el microcontrolador TM4C123GH6PM por los últimos tres años, enseñándolo en el laboratorio de electronica en la Universidad de San Carlos de Guatemala.

De igual manera cuento con material en español para comprender la teoría detrás de los códigos por si alguno esta interesado.

DAC38RF80: Internal block level diagram
Part Number:DAC38RF80
Hello,
I want to confirm the internal level diagram.
There are roughly blocks which interpolation, IQ mixer, SINC filter and DAC. When Input digital signal is assumed x [dB], I would like to know the output level of each block.
1. Interpolation output
Frequency response is in figure 58 to 65. The gain is typically 0dB so output power would be x [dB].
2. Mixer output
When Mixer Gain = 0, summed IQ power is 3dB loss. In this case, the output power is (x-3) [dB]
When Mixer Gain = 1, summed IQ power is 0dB. In this case, the output power is x [dB].
3. inverse SINC filter
Figure 67 is the frequency response. Roughly gain is 0dB if the RF frequency is below 0.4 x fDAC. so the output power is x[dB], mixer gain =1 case.
4. DAC
when default, DAC gain is disable case, DAC will ouptut the power as same as the digital signal so the output power would be x [dB], mixer gain = 1 case.
Please correct me if my understanding is incorrect.
Best regards,
Toshihiro Watanabe

Hello experts,
I have a u-boot.bin file that needs to be written to location 0x40000 on a NAND device (happens to be exactly where MTD partition 1 begins). Here's how Linux sees the NAND partitions:
Creating 7 MTD partitions on "davinci_nand.1":
0x000000000000-0x000000020000 : "u-boot env"

0x000002400000-0x000020000000 : "filesystem_large"
How can I take the u-boot.bin file and get U-Boot to load it in from location 0x40000 ? (Don't think just using AISgen will do it)
Any help would be greatly appreciated. Consultants are welcome (we're in a time crunch..)
much thanks,
