Part Number:BQ51050B
hi dears,
a customer of mine is interesting in evaluating our wireless charging solutions.
For this purpose, he is looking at BQ51050BEVM, but I couldn't find any.
is it possible to get a spare board of a reference design using the BQ51050B?
also, may you point me out some app notes on Qi coil design and/or better combination of NFC+Qi coils?
thanks a lot in advance

Hi,
Is there any way to disable the feature of emergency shutdown triggered by pressing power button (driving PWRBTN low)? The purpose is not triggering emergency shutdown no matter how long that PWRBTN is driving low.
Thanks!

Dear Champs,
My customer faced I2C line hang and resolve it referring below. They are trying to apply recommendation 2 in below.
But, they failed to resolve I2C communication hang with method 2 and requested to let them know how 'free data format' should be set to resolve issue.
Could you please let me know exact sequence to set 'free data format'?
Or could you please check below my customer's code to set 'free data format'?
They set FDF bit in ICMDR register as below, and they found it worked well in normal IDLE case(data=0xff).
In issued situation, they failed to resolve 'SDA Low' issue and there is no SCL even after 100 retries.
voidi2c_free_data_format(PI2C_REGS_T i2c) { unsignedint icmdr, irq_status; unsignedint retry = 0, timeout = 0; unsignedchar data = 0;
while( data != 0xff ) { icmdr = I2C_ICMDR_IRS | I2C_ICMDR_MST | I2C_ICMDR_STT | I2C_ICMDR_STP | I2C_ICMDR_FDF;
/* i2c mode register set */ writel(icmdr, &i2c->ICMDR);
for(timeout = 0; timeout < 100; timeout++) { udelay(100);
irq_status = readl(&i2c->ICSTR);
if(irq_status & I2C_ICSTR_ICRRDY) { data = readl(&i2c->ICDRR);
for(timeout = 0; timeout < 100; timeout++) { udelay(100);
irq_status = readl(&i2c->ICSTR);
if(irq_status & (I2C_ICSTR_SCD|I2C_ICSTR_NACK)) break; } break; } }
/* clear interrupt status register */ writel(0xffff, &i2c->ICSTR);
/* clear mode control register */ writel(0, &i2c->ICMDR); writel(0, &i2c->ICMDR);
retry++; if(retry == 100) break;
mdelay(1); }
console_printf("\nFree Data format SDA [0x%02x] Retry [%d]", data, retry); }

Hello TI
What is the minimal off-time for the upper FET needed to recharge the bootstrap-C?
To calculate this, I would need a inner R of the charge path, so I can calculate a RC-time-constant of the charge-circuit. I will be using a 0.1 uF bootstrap C as recommended in the manual.

i'm using dm8148 and dvrrdk_04.01. when running, how to find out which range of physical memory address linux is using(e.g. 0x80000000-0x90000000 or 0xa0000000-0xb0000000)?
Part Number:EVM430-F6736
Hi,
I have received an EVM430-F6736 Kit as my final-year project in my University. My project is to combine the smart meter with the Arduino Uno WiFi to send the necessary data to the Thingspeak cloud.
I found the schematic diagram of the EVM430-F6736 and it has the EZ-RF connect. Will it be possible to connect the Arduino Uno WiFi board to pin 1 (TX0) and pin 6 (RX0) of SV3? If yes, what is the method?
Hope to hear from you soon and many thanks!
Best regards,

Part Number:TCI6630K2L
What’s the correct and current EVM part number to support TCI6630K2L? ESP suggests that it’s XTCIEVMK2LX, but that’s NOT OK TO ORDER and NOT OK TO SHIP.

Hi,
if you put a low frequency sinewave into two devices,configured as PBTL and with same load,same external components, what is the max output phase delay difference between them?
Thanks

Hi team,
Could you support below questions from my customer?
Initial state: Vsup=OFF, Vcc=OFF
Step1: Supply Vsup > Vsup_UV, and Vcc is kept OFF
Step2: Wait for more than tUV
Q.1) Does device shift to Sleep Mode with above scenario?
Q.2) If yes, which rout will the device pass?
Device directly shifts from Standby to Sleep mode by Vcc_UV detection?
Q.3) Is there any indication that device is staying in Sleep mode with above scenario?
Best regards,
Nobuo Fujihara
Part Number:LM6172
Hi all,
In the following circuit, when enable input is float, i see 700mV dc voltage at inverting input of opamp. Thus, there is 70uA current from inverting pin of the opamp. However, LM6172 datasheet states that max bias current is 4uA and max offset current is 3 uA. What is the reason of this current? Is this normal?

Part Number:TIDEP-0091
Hi everyone,
I'm currently experimenting with IWR1443BOOST board.
I need to modify the TIDEP-0091 source code to get high accuracy range measurement. Actually I need to modify the TIDEP-0091 source to get the accuracy of "Industrial tool box - High Accuracy Range Measurement - 14xx lab".
I understand that the power consumption may not meet the level transmitter requirements. I'm not concerned about the power consumption at the moment.
Since. the High Accuracy Range measurement lab requires the config data loaded from the PC each time, all I need is to get high accuracy range measurements without connecting to a PC.
I went through the source codes of the two projects, but I'm bit lost with understanding the order of configuration with CLI based config. of high accuracy lab.
How can I modify TIDEP-0091 source code to get high accuracy range measurements? Could someone help me with the steps I need to follow to modify the source code?
A guidance for this is highly appreciated.
Cheers,
Randy

Hello Team,
I have to design a USB Type C DFP and I decided to use TI Products.(USB1046 and TPS65981) One Basic condition in my design is that I must support industrial temperature ranges. (-40°C to 85°C)
Is this the best choice in reference to conditions like power consumption and space?
What I need:
USB TYPE C with:
+ PD max. 36W
+USB 3.1 Gen 1
+DisplayPort
+USB 2.0

Hi,
I´m facing a problem while using both, the ADC and the COMPB, in my Sensor Controller tasks.
For better understanding, here a brief description of my setup:
Like you see in the picture, i have 2 tasks on my sensor controller, one does some pressure measurement (DIO 23&24) and the other only measures the input of one analog pin (DIO30) with the COMPB and compares it eith an internal voltage. The pressure sensors are, at this time, replaced with potentiometers for testing purpose.
Now to my problem:
When I only run the comparator task, everything works as expected, the DIO30 gets measured, is compared with an intern voltage and i can read the comparator output via scifTaskData.comparator.output.charging in the main program.
When both tasks are activated, it seems like positive input of the comparator is using the value of the ADC, so it doesn´t compare DIO30, but it compares DIO24 (i first measure DIO23 and then DIO24 in the measurement task) with the reference. I think it has something to do with the shared input of the adc and the comparator. It also makes no difference, which task is the first to run.
Is there a way to fix this problem, or do I have to use the COMPA, when using the adc on the Sensor Controller?

Hi Kumar,
I am trying to compare the inference output layer by layer in normal bvlc caffe and TIDL Host Emulation.
Only first layer output of TIDL Host Emulation, I could match with bvlc caffe (Because it is just the input image as it is). Rest of the output , are not matching. Is there any proper way to validate bvlc caffe trained model and TIDL converted caffe model.
1. BVLC Caffe
- image.jpg
- deploy.prototxt
- model.caffemodel
- Here I have written a quantization code same as TIDL in python.
- Conv Layer output which will be in floating points , I am quantizing to 8 bit . To match this with TIDL Conv Layer Output
2. TIDL Caffe (Host Emulation)
- image.y
- deploy_net.bin
- model_param.bin
- During inference, let say i am getting conv layer output in out trace_dump_0_50x50.y
- This is already a quantized output. So, I am trying to match this with BVLC caffe quantized output.
I have also written python scripts for conversion of .y having shape (1x n ) to .data having shape (h,w, ch) and vice a versa.
I am not getting same output .
Is the above method correct ?

Sagar
