TS3A226AE: C2 Pin NC

Part Number: TS3A226AE

HI ：

I am using TI TS3A226AE, and I have the following questions to consult, please help to solve them, thank you.

TS3A226AE's datasheet C2 Pin TIP function is involved in independent identification, which is detected and identified by comparing the impedance between TIP and ring2 and TIP and sleeve Pin.

My question:

1.Will there be any problem if C2 Pin is not used?

2.If we don't use the detection and identification function of C2 TIP.We write our own detection algorithm, and switch through our own software.Is C2 pin suspended, which will affect the normal use of chip analog switch?

thank you ,looking forward to your reply

CCS/CC1310: Sensor node clock synchronization with collector time

September 6, 2019, 3:31 am

Part Number: CC1310

Tool/software: Code Composer Studio

Dear TI,
we are trying to implement a clock synchronization (in the order of tens ms) between sensor node and collector, with the TI15.4 stack.

At this time we are using non-beacon mode and at regular interval we send a packet sync request from the sensor node to the collector. When the collector receives the sync request we send a sync response with a payload containing the local time in unit of 100us (linux).
So, using the clock offset from the collector and sensor node we are hoping to successfully manage the clock sync process as listed in your reference page: http://dev.ti.com/tirex/content/simplelink_cc13x0_sdk_1_00_00_13/docs/proprietary-rf/html/rf-proprietary/time-synchronization.html.

But, we cannot getting the expected result and the offset still be grather than tens of seconds.

Do you have any further documentation to implement clock synchronization at application level?

Thank you very much
Best regards

L.s.

I have few questions about the availability of TL5500 Low-Noise Pre-Amplifier for Magnetic Resonance Imaging (MRI).
Would you please send me some detailed information about this part.

Is this part still available or is it discontinued?

Is there a newer reference design, or a replacement for the TL5500?

What is the minimum order quantity and do you have reference pcb designs available?

Kind regards.  Corné Jacobs

BQ34Z100-G1: Internal temperature sensor losing calibration

September 6, 2019, 4:13 am

Part Number: BQ34Z100-G1

Hello,

I am using the BQ34Z100 device as part of a custom battery management system.  I am using the internal temperature sensor, and have set the pack configuration accordingly.  When I first calibrated the system using bqStudio, I noticed that the sensor was reporting the correct temperature, and did not require calibration (offset = 0).  However, after using the system for a while, including running a discharge cycle, the sensor started reporting an incorrect temperature.  I was able to re-calibrate, but the offset value is almost at its limit of -12.8 degrees C, and I am worried that any further shift will result in an unusable temperature sensor.

To remove any doubt, the sensor was originally reporting the ambient temperature of approx 25°C but suddenly switched to reporting approx 37°C, with no change in ambient temperature, and minimal current being drawn by the system.  The device is remote from the power supply.

Can anyone explain why the temperature sensor would suddenly shift by this amount?  It has now happened twice with two independent devices, and obviously I cannot have a sensor that keeps changing its calibration offset value.

Thanks in advance,

Julian

Hi Team,

          I saw the LM393 and LM2903 is the same datasheet. May I know what  the difference of supply power between LM393 and LM2903 is?

There is my point:

LM393 can support dual supply power, +18V to -18V, while LM2903 is singal  supply power, 0V-36V. 

Is it right?

Thanks!

Part Number: BQ24296

Hi,

Have  working BMS prototype board  using BQ24296  Battery Charger, BQ27542 Fuel Gauge, BQ29701 protection IC. Functionally all the ICs are working fine.

Charger IC/Inductor is getting heated up when current limit is increased to default   max ( Ilimit R = 120 ohm), with charging current at its default value of 2A.  On a few boards charging IC failed.

Part of the schematic is below. Please review and suggest what could be wrong.  Inductor used is  IHLP2020BZER2R2M01 / Vishay make

Also, please review the ground path. All ICs ground are connected to  B- now. Is it OK ? 

Would like to send entire schematic for review in a private message.  

Thanks in advance for help.

CC2530: ZCL Reporting Atrributes

Part Number: CC2530

Hi Guys,

I´m working to implement the message report attribute according to ZCL foundation, using the "push" method attribute reporting, the devices themselves send reports when the attribute changes. In my case, I using the ZCL_CLUSTER_ID_GEN_ON_OFF, but when I check the message sent by device, over the air,  I saw that has malformed ZCL parameters. It can be seen on PIC attached.

I have configured in my APP file the parameters as you can see below:

/*********************************************************************
 * GLOBAL VARIABLES
 */
zclReportCmd_t rptcmd;

Init was configured in the ZCL cluster parameters:
//reporting attributes configuration

rptcmd.numAttr = 1;

rptcmd.attrList[0].attrID = ATTRID_ON_OFF; // Attribute ID of OnOff included in the Cluster Gen On/Off is 0 (ZigBee Cluster Library spec)

rptcmd.attrList[0].dataType = ZCL_DATATYPE_BOOLEAN;

rptcmd.attrList[0].attrData = (uint8*)&zclTTa0003_OnOff;


ZCL Reporting CMD was inclued in My APP OnOffCB:
static void zclTTa0003_OnOffCB( uint8 cmd )
{
  afIncomingMSGPacket_t *pPtr = zcl_getRawAFMsg();

  zclTTa0003_DstAddr.addr.shortAddr = pPtr->srcAddr.addr.shortAddr;


  // Turn on the light
  if ( cmd == COMMAND_ON )
  {
    zclTTa0003_OnOff = LIGHT_ON;
	seqNumb++;
	zcl_SendReportCmd(TTa0003_ENDPOINT,&zclTTa0003_DstAddr, ZCL_CLUSTER_ID_GEN_ON_OFF, &rptcmd, ZCL_FRAME_CLIENT_SERVER_DIR, false, seqNumb );

  }
  // Turn off the light 
  else if ( cmd == COMMAND_OFF )
  {
   zclTTa0003_OnOff = LIGHT_OFF;
   seqNumb++;
   zcl_SendReportCmd(TTa0003_ENDPOINT,&zclTTa0003_DstAddr, ZCL_CLUSTER_ID_GEN_ON_OFF, &rptcmd, ZCL_FRAME_CLIENT_SERVER_DIR, false, 0 );

  }

I see in the ZigBee Cluster Library Quick Reference, as you see below, that All those parameters included in zcl_SendReportCMD are right but I cat in Wireshark, file attached, that has malformed parameters. 

Does someone, please, give an idea of how to fix it?

OS : Windows 10 Enterprise(April 2018 Update(1803))
Tool : simplelink_cc2640r2_sdk_3_10_00_15

<Question>
(1) Is the communication method Bluetooth 5 or Bluetooth 4.2?
(2) About the accuracy of AoA
　In my experiment, accuracy becomes worse when the distance between passive and slave exceeds 0.5m.
　How many meters and how many meters is the range of distance that can be calculated?

 

(3) About the calculated distance of ToF
　In my experiment, the distance between passive and slave is about 0.3m, but in the graph it is 5.0m to 10.0m.
　Is it necessary to edit the sample program necessary to calculate the correct distance?

(4) To accurately calculate the distance from passive to slave, we believe that both AoA and ToF are required at the same time.
Is it possible to output AoA and ToF as a graph at the same time?

Hi,

I bought a cc2642 launchpad from TI store. It is not getting detected, so after checking online i tried the below recovery method but still it is not working.

"Recovering a Bricked XDS110 without JTAG
In the case that your XDS110 fails to enumerate as a USB device, or it fails to enter DFU programming mode, you can attempt the following steps to force it into DFU mode to recover:
1. Ground the JTAG TDO pin of the XDS110's Tiva CPU. This is pin 97 on the 128 pin device. (Check the TM4C1294NCPDT datasheet for the pin location; it is located on a corner and easy to access.)
2. Unplug and re-plug the XDS110 into the host computer while the pin is grounded.
3. The XDS110 should now be in DFU programming mode.
4. Remove the connection to ground while the XDS110 remains powered.
5. Use the xdsdfu utility to update the firmware as detailed above."
