Part Number:TPS650941EVM-116

Hi,

When evaluated by EVM, Vgs of low side FET (CSD87381P) was confirmed to be a voltage exceeding min (1.2 V).
I think this is due to the self turn on.

Is there any problem that EVM will cause self turn on?
The conditions are Vin = 12V, Vout = 1.1V, Iout = 15A.

Best regards,
Yuto Sakai

Part Number:LOG112

I want to give the output from a photo detector,in that case how we  provide  input to I1.using current source? or current generator? .can u plz explain the reason also.

Part Number:CC1200

Hi Team,

Can CC1200 support OFDM transmission?

I can not see the CC1260 datasheet in its product folder. Could you tell me how to get it?
It's nice if you can tell me the difference between CC1200 and CC1260 as well.

Hi,

regarding this question https://e2e.ti.com/support/processors/f/791/p/801262/2986630#2986630, sorry for the late reply, been busying with other project.

To reply to lding:

We are using SBL. Do you have any sample driver code for USB3.0 that works in Windows10?

Thanks.

Part Number:LM4950

Hi Sirs,

Would you please advise if the thermal pad under the LM4950TS device grounded? Is there concern of OCP if we connect the thermal pad to ground plans?


Thank you and Best regards,

Part Number:TPS65987EVM

To whom may it concern,

I will purchase TPS65987EVM.

Does it include a Cable-connector mated by J2 Expansion Connector?

If no, What is P/N of the cable-connector mated by J2 Expansion Connector?

Please reply for me.

Thank you.

Part Number:TLV755P

hello sir,

i have issue with tlv755p ic .i have fix 3.3 volt type.when i first time check i get proper output. but after switch off to on i am not getting my 3.3volt.i can't understand my problem.

please help me.

Part Number:CC2650

Tool/software: Code Composer Studio

After updating the flash file simple_np_cc2650lp_uart_pm_xsbl.hex with cc2650 launchpad, the Bluetooth module works normally, but the signal is a little weak. There are 2 2 pF to 11 pF load capacitors inside. Can it be configured as 9pf, you need to modify the ccfg.c file of the Bluetooth protocol stack. After the modification, the following two are all written to the Bluetooth module through the ccs connection cc2650 launchpad, but the Bluetooth module after programming is abnormal, there is no signal, use the cc2650lanuchpad connection to make the Bluetooth module, burn the above two folders, there is no In sequence, whether these two folders are burned is equivalent to burning the simple_np_cc2650lp_uart_pm_xsbl.hex file. Why is the Bluetooth signal sent by the cc2650 not detected after the dbug is burned? Is it missing?
Thank you!

The minimum switch peak current limit in the specification is 0.8A
The maximum load required for the backend may be at 800mA
Can you use it, what is the difference between the two?

Part Number:SN65DP159

Hi team,

Did we got any suggest solution to compare with MegaChips MCDP2900?

Not sure that SN65DP159 is suitable candidate or not.

Thanks

Part Number:MSP430F5529

Tool/software: Code Composer Studio

Hi,

I am currently using DRV8323RS with MSP430F5529 to run a sensorless BLDC motor.

I am trying to create a standalone program without the use of GUI.

When I supply voltage to the DRV8323RS board, I would like the motor to automatically run CW or CCW continuously without using GUI since I have to run a life test of 25 min ON, 5 min OFF and repeat.

With DRV8323RS, I downloaded the source code for sensored and sensorless for CCS.

I managed to create a program for sensored motor and is able to run the sensored BLDC motor

However, when I tried to replicate the codes for the sensorless BLDC motor, the motor doesn't turn on. I measured the voltage at the high and low gates and noticed that GLA, GLB, GLC is reading some voltage (~ 10Vdc) while GHA, GHB, GHC is reading 0V. I believe that is incorrect.

Is it possible to have a look at my codes? If yes, I can send you my codes in a separate email if necessary.

Please advice.

Appreciate your help.

Thanks,

Thena

Part Number:CC2640R2F

Dears：

Could you kindly help to give some advice about beacon data？

Now customer uses cc2640R2F to simulate beacon data to send on 2402 MHz, which can be received by mobile phone. 

But  the same data using frequencies are 2426 MHz and 2480 MHz, which can not be received by mobile phone.

And customer can confirm the mobile phone can receive beacon data under frequency of 2402 MHz, 2426 MHz and 2480 MHz by other device.

Could you kindly help to give some advice?

Part Number:DAC3482

Hi,

Below shows the normal floor noise and output signal of DAC3482 in this board.

But sometimes after power-up of the board, the floor noise of DAC3482 is much bigger and there is many spurs near the output signal. When this happens, it can be solved by tuning Reg_0x24. Could you pls suggest any method that I can try to avoid this issue? What is the possible root cause of this issue? There is another DAC3482 with same schematic and register setting in this system which is programmed later after power-on. I didn't find the same issue in this later one.

Thanks.

Tool/software: Code Composer Studio

Hello!

I'm trying to implement a bootloader in my project based on simple peripheral BLE example. I need to move the application program to pages 1 - 30 and let the reset vector be in the beginning of flash page 1. 

In cc26xx_app.cmd I changed:

#define FLASH_APP_BASE 0x01000 
#define FLASH_LEN 0x1F000 

Then in cc1350.cfg:

m3Hwi.resetVectorAddress  = 0x1000;

Then I got this error. But when i comment ROM lines, I'm getting compilation error:

"C:/ti/simplelink_cc13x0_sdk_3_10_00_11/examples/rtos/CC1350_LAUNCHXL/blestack/simple_peripheral/tirtos/ccs/config/app_ble.cfg", line 1

Part Number:CC2538

Hello,

I am using osal_GetSystemClock() function for a blocking timer in a while loop below is my code

osalTimeUpdate();
start_time = osal_GetSystemClock();

while(20000 >= stop_time )
{
osalTimeUpdate();
stop_time = osal_GetSystemClock();
stop_time -= start_time;
}

Here i want to achieve a blocking time of 20 seconds but actually i am getting 12 seconds time when i run a stopwatch using debug points before and after this code.

what can be the issue?

Regards,

Akshay

MOUT PIN IS GROUNDED THROUGH RESISTOR Rmo= 1.13k

Cao pin is at 0V. Gate pulse is not coming. Please suggest.

Part Number:AFE4404

Hi,

From the AFE4404 datasheet, the sequence for 3-LED mode is LED2 → LED3 → LED1 → Ambient.

And now I'd like have the sequence (LED2 → LED1 → LED3 → Ambient) with my custom board based on AFE4404.

Then I have modified the corresponding timing signal (LED1<->LED3)

But I found the signal is not what I want, the LED1VAL in register 2Ch seems to still be the 3rd lighting one.

So I just wonder what is the x in LEDx described in datasheet?

The order for lighting LED or the wiring to TXx pin?

Regards

Gary
