Part Number: LSF0102
Hi,
For the schematics as shown in the attached word file
While connecting only the 3.3V side (pin 7 and 8), we see 0.8V on pin 2.
Is this normal behavior or malfunction?

SRC4382EVM-PDK: digital audio recording
Part Number: SRC4382EVM-PDK
Hello
I have an src4382/92EVM kit and want to use this for digital audio input so that i can record input using software tool like ffmpeg. when i connect the board using usb with my centos (linux) pc it shows audio card for input and out put and using arecord command i can find device in list. i want to take input from XLR input port (balanced digital audio) which is J5 and using command line i want to record audio but the thing is that when i run the command i can see that some thing is recording but when i playback that audio file i could not be able to here any sound. i am running following command - ffmpeg -f alsa -i plughw:1,0 -c:a mp2 1.wav

TPS65910: TPS65910:About the output waveform of VAUX2
Part Number: TPS65910
Hi
I use a combination of TPS65910A31A1 and AM3354 in the product.
The output of VAUX2 of TPS65910 as shown in the attached figure Output with timing and voltage different from the setting.
The settings of TPS65910 are the same as Table 2 of SWCU093F. (VAUX2 = 3.3 V)
1.Is this a specification of this IC?
2.If it is not a specification, is there a way to improve it by setting etc.?

Please forget bad broken screen issue.
After comfirm , it's due to the cable wrong pin assign to edp lane.
I have replaced a new correct cable , but the semi-auto link failure issue is still as below dump :
2) After I did the DP training twice times , The display is normal work . please give advice ?

TPS65988: Status check
Part Number: TPS65988
Hello Eric,
I would like to confirm which profile was established as a result of negotiation.
I want to use SRDY to turn on the switch if the result is met with the intended profile.
And I want to supply power to the device in the latter stage. Which status register should I check to do this?
Specifically, I want to confirm that the source side has a 1.5A supply capacity.
For example, even though a manufacturer's product specification requires typeC to TypeC,
I am thinking of a situation where the user uses a typeA to typeC cable. At this time,
if only 500mA can be supplied, I would like to create a mechanism that prevents the latter system from starting up.
Best regards,
DDdoor

DRV8848: GUI cannot work properly.
Part Number: DRV8848
Hello Sir,
Finally, I can install the GUI successfully.
During the installation, I found my screen is different with sllu210b.pdf instruction.
In "sllu210b.pdf - figure11" show below:
In my installation, there is not the "Lauch DRV8848" as below. But is is not big deal, just let you know.
After installation, I executed the GUI program, it should the message below:
I try to link the file, by using "Browse..." to the below file:

DS90CF384AQ-Q1: Color Mapping data
Part Number: DS90CF384AQ-Q1
Hi team
Color mapping data of the DS90CF384-Q1 is not find in the datasheet.
Data sheet of the DS90CF386 was contain Color Mapping (Table 2 & Table 3).
Are the color mapping data of DS90CF384-Q1 and DS90CF386 the same?
If not, please share color mapping data for DS90CF384-Q1.
Thank you.

TPS92612-Q1: linear constant current LED driver with fast response
Part Number: TPS92612-Q1
Hello experts,
My customer is looking for linear constant current LED driver which has fast response (within 100ns) like NSI45020AT1G.
By using TI.com's cross reference tool, I find TPS92612-Q1. This device has same feature, but response scale is little bit difference.
Do you have any other suggestion?
Thanks and best regards,

TLV320ADC3140: What is the power consumption of ADC3140 if the power supply are all 1.8V
Part Number: TLV320ADC3140
Hi Team,
In datasheet we only have the 3.3V AVDDDVDD and 1.8V IOVDD power consumption data in the datasheet. Do you know if it was run in 1.8V mode, what is the power consumption level? The customer is looking for 5mW/CH ADC, could it meet? If Digital MIC could has lower power consumption, we also can provide them the data with the digital MIC.

BQ4050: Please help with the mass prodution
Part Number: BQ4050
Hi Dear,
I am working on bq4050(CEDV gauge) BMS for the last couple of months. I am able to get the required parameters for golden file creation and finally, I Updated the FCC value to the desired value.
I have gone through the steps in this video (https://training.ti.com/bq40z50-setup-and-going-production) for mass production of chips.
I have a few doughts :
1. Golen file used in the mass production can able to update the FCC value or not?
2. If the golden file is not able to Update FCC, then what are other alternatives to update FCC?
note: Our application is not suitable for the field update of the FCC.
3. Do I need to run the qualified discharge for each pack in the mass production also?
In order to run the qualified discharge for each pack, it is really too difficult and time-consuming process.
If possible, provide me with a chip number, that should reduce the all-over headache mentioned above.
Thanks & Regards

Hi Team,
Is there any spec of sequence about VCCX and VIN?
For reducing power consumption, I'd like to use external supply for VCCX but this maybe applied faster than VIN.
In this case, Is there any concern?
