Part Number:BQ76940
Hi,
To read the voltage value of V5 and V10, we see the voltage are unstable, and we think that should be the voltage drop on the resistor R18/R30 due to power sink from V5 and V10.
And the voltage become stable after modify resister to 100Ohm.
Please check the link below for schematic detail, thank you.
Thank you.

Part Number:TPL5110
Dear everyone,
Recently, I have a project to make a control board for LED driving.
I need to make a timer to turn on and off LED light.
Want to adjust its total period time and turn-on time with resister or dip switches.
So, I decided to use two TPL5110 to make this pulse signal to turn on the LED driver.
Would you recommend if it works?
I am concerning if M_DRV works with a falling edge signal coming from the other one's DRV.
Thanks.
Part Number:DAC8881
Hello,
To perform a reset, /RST pin must be asserted to low level. (datasheet page 28).
I don't find the information about the minimum duration needed to be sure that reset is perfomed into the chip before asserting /RST to high level.
Best regards,
Flavien
Part Number:LM5170-Q1
Hello!
I meet some issue when debug my LM5170-Q1 board. the schmatic is refer to LM5170EVM-BIDIR, and the Design Calculator . the condition is 50Vin, 12Vout1/50A, 12Vout2/50A.
the DC source is the battery model.
1. I set the OVP point is 17V on the 12Vout, But it can't protect when reach the point.
2. It only can load 1A each channel.

Hello
every expecter
I have use a usb_serial_device of StartWare , when I connect to PC (windows 7) , there "unknown device" pop up.
and then pull off usb cable, connect again there are corect message of " StarterWare USB serial port".
Could you tell me how to set the register, when connect PC first time that show me the "StarterWare USB serial port" ?
wait your help.

Part Number:CC1310
Hi,
Could you please let me know if there is any way to find out the exact time CC1310
is consuming to erase and program?
In our application Flash will be updated through bootloader(UART) from an external MCU,
and we want to calculte the wait time required for the total Erase/program of the new program
so that we can set a timeout period at the external MCU.
Total program size would be 128KB.
As per the datasheet erase time TYP is 8ms and write time 8us,
So we are thinking about setting the timeout period of 1000ms, will this be a feasible time?
We are worried about the Note: mentioned in the datasheet saying "Flash write/erase time is dependent
on Flash aging and will increase over time and erase cycles".
We are not sure how much would it increase over time.
Best Regards

Part Number:AMC1301
Hi Team,
My customer is considering to use AMC1301 to replace ACPL-C790 and he has a question regarding safety certification.
ACPL-C790 pass the certification of EN 60747-5-5, AMC1301 pass VDE V 0884-10. What is the difference between these two certifications?
Does AMC1301 need to pass EN 60747-5-5 to help his product pass UL certification?
Thanks a lot.

Question about configure the DIG_IF_CTRL status register.
When after activate I2C communication, can I2C configure DIG_IF_CTRL register?
MCU have only I2C interface(SDA and SCL), I hope to configure all setting by I2C interface only.

hi,
i want to implement a central device using the simpleBLECentral project which can be connected to a keypad running keyfob project in it. i was able to connect to the device, but couldnt make data transfer from the keyfob to SimpleBLECentral. how can i make use of simplekeys profile in simplleblecentral (gatt client) to receive button press event from the keyfob(gatt server).how to do this?
Part Number:MSP-EXP432P401R
Tool/software: Code Composer Studio
Hi,
I'm trying to find a MCU fit for my application. Now, I use the MSP432 launch pad.
I wonder where I can find the memory size information from the CCS?
I looked at the.map file, so:
The flash size is: 7434+329+1074 (kByte), right? But where to get the RAM size occupation information?
Part Number:DRV8871-Q1
Hi team,
Greetings. I have a question about the VM bulk cap of DRV8871-Q1.
The parameter is that VM=12V coming from automotive battery, normal working current=1A, stall current=2.5A.
Duty cycle is 100% only using high or low voltage level to controll.
Can I just use a 1uF ceramic cap here? Is there any drawback?
What if I use 10uF ceramic cap or a bulk cap? Any problems?
Customer said they used 0.1uF cap on VM pin when they used two half bridge chips before, there was no problem.
Look forward to your reply.
Thank you.
Best Regards

Part Number:TMS320F28377D
Tool/software: Code Composer Studio
Hello.
I build the project in CCS 7.1.0 and generate a HEX-file using standart C2000 utility.
Here are first two lines of HEX-file:
%1263980008000048E6
%4E68C800082000C6080C0814081C083A0858087808A808B408D308E708F708070817083B084C08
Then I go to debug mode, load the same project to flash and look at Memory browser. I expect to see the same bytes which I see in HEX, but what I see is (16-bit HEX TI style):
0x00080000 0048 B1E6 FFFF FFFF FFFF FFFF FFFF FFFF
...
0x00082000 77C6 0008 780C 0008 7814 0008 781C 0008
0x00082008 783A 0008 7858 0008 7878 0008 78A8 0008
0x00082010 78B4 0008 78D3 0008 78E7 0008 78F7 0008
0x00082018 7907 0008 7917 0008 793B 0008 794C 0008
It looks like the data bytes from the HEX-file (48 E6 C6 08 0C 08...) are interleaved with 00 B1 77 00 78 00...
What is the origin of these unexpected bytes? How to consider them when doing Flash API programming/verifying?
Hi,
When I am using versión SDK v2, I am getting this error:
error #10008-D: cannot find file "/home/antonio/ti/simplelink_msp432p4_sdk_2_10_00_14/source/third_party/fatfs/lib/fatfs.aem4f"
error #10010: errors encountered during linking; "TFG_0.002.out" not built
But if I use SDK 1.6 I am not getting any issue.
If I check directory structure in SDK v2:
:~/ti/simplelink_msp432p4_sdk_2_10_00_14/source/third_party/fatfs/lib$ ls
ccs gcc iar
and in SDK v1.6
~/ti/simplelink_msp432p4_sdk_1_60_00_12/source/third_party/fatfs/lib$ ls
fatfs.aem4f fatfs.am4fg fatfs.arm4f
Any idea?

Part Number:TMS320F28377S
Tool/software: Code Composer Studio
Dear Sir,
I've used the reference code given in adc_soc_epwm01 or adc_soc_software01 of v200 for TMS320F28377S in CCv7.0. I'm getting the adc_values in result registers. But if i run the code using continuous refresh, it hangs at asm(" ESTOP0"). Therefore, it doesn't notice any change of voltage at adc pin Ao. Please help me to resolve this issue that is update of adc value. 
Part Number:TDA2
Hello,
The customer would like to know the min/max height of TDA2 ABC package after soldering.
They want to know exact thickness of TDA2 ABC to attach thermal pad.
In TDA2 ABC data manual, min/max height is 2.62/2.96 and seating plane is 0.15.
Hence, the min/max height after soldering TDA2 should be 2.47/2.81. correct?
Thanks,
Lloyd
