Compiler/CC2540EMK-USB: project hardware of semi-active RFID using 2.4Ghz blutooth cc2540
Part Number: CC2540EMK-USB
Tool/software: TI C/C++ Compiler
hello all,
now I am struggling to know the way I know to do my project.
I have 2 CC2540 USB dongle devices, I have already made them connect by using Btool. I have no idea to communicate like when one CC2540( master ) sends a notification to slave and the slave receives it and blink the led. additionally, I want them to connect automatically, for example, the master memorizes the slave's name and automatically connects when approaching
Thanks for reading my post !!

IWR6843AOPEVM: Connect but failed GUI application
Part Number: IWR6843AOPEVM
Hi,
I got two IWR6843 AOP Plug-in module today. I used uniflash to program the "aop_pplcount_lab_68xx.bin" of lab20 to both module. And use the "GUI_A_base_no_logic\main_pplcount_viz.exe" to execute the people count evaluation. I did install the "CP210xVCPInstaller_x64.exe" SICP2105 UART driver, set the UART port with Enhanced COM, set DATA port with Standard COM and reboot my PC before evaluation above. The result is I successfully execute "main_pplcount_viz.exe" people count on my first module but failed on the second one. The error message in console as following: Please help how to fix it on my second module, or the module is actually as NG module?

SN74LV4052A: Maximum continuous current through internal protection ESD diode when VDD is 0V
Part Number: SN74LV4052A
Hi Team,
May I know the maximum continuous current through internal protection ESD diode when VDD is 0V and input is 3.3V? Is input clamp current the maximum continuous current?
Because we want to protect SN74LV4052A by using a load resistor on VDD in case VDD is 0V. In the final design, we will use a mux with powered-off protection.

CCS/CC1352R: link quality and raw correlation
Part Number: CC1352R
Tool/software: Code Composer Studio
Hi All,
I am working with CC13252P collector. My requirement is along With RSSI level I need to print link quality of received frame and correlation value I did and found as follows:
As per my knowledge lower the values of link quality higher the strength of the frame and link quality varies accordingly with RSSI if RSSI is low then then link quality value should be less but I found that values that I got is RSSI value more hen link quality value decreases.Along with I found correlation value as 0. Please give me solution ASAP.

BQ27Z561-R1: BQ27Z561YPHR-R1 sleep mode input current probem
Part Number: BQ27Z561-R1
Hi TI team,
Could you pls help us help us confirm whether the input current 45uA/46uA is normal in Sleep Mode?
The datasheet only said sleep mode typical value 11uA,no said the Max value
The measured data was captured on Debug bench, the test condition on Debug bench as following.
- PSU set to +2.8V, DMM set to current range.
- Connect PSU “+” probe connect to DMM current pole.( PS: PSU accuracy isn’t enough, only show 4 bits, can read ma current but can’t read uA current. the DMM can show 6 ½ bits, can read uA current)
- Connect the DMM current probe to PCBA Vb, the PSU”-“ probe connect to PCBA GND.
- On PCBA power on beginning stage, the PCBA current will reach to about 6ma; after wait for 2S( entering sleep mode), the good PCBA current will drop down from 6ma to 15ua. However, the NG PCBA current only drop down to 46ua. The different value is 30ua between NG sample and good sample

BQ34Z100-G1: Higher capacity(>29Ah) & higher current(>29A)
Part Number: BQ34Z100-G1
I want to use BQ34Z100-G1 in one of my projects for battery gauging purpose but the battery capacity is >30Ah & current is >100Amps.
Battery Pack is 13s13p NMC(18650) cells of 2600mAh.
Battery Voltage is 54.6 Volts. Capacity is 33.8Ah. Max Discharge current 130Amps. Charging current 20Amps.
How to select the resistors for voltage divider circuit? In SLUA760 calculation is given with respect to voltage only.
How to design the translation circuit for higher current & capacity?
What should be the values & ratings of resistors, NMOS?
As it should not damage the IC and gauge will work properly.

TLV2462A: TLV2462 capacitive load driving capability
Part Number: TLV2462A
One of my customer is using TLV2462 rail-rail op amp for pressure sensing application in our product. As per datasheet if capacitive load more than 10pf then suggested to use min 20ohm resistor in series, what will be the maximum capacitive load that op amp can drive without degrading performance?. Initially they used 1K resistor in series for 0.1uf capacitive load but at some point of time op amp output limited around 3.5V even though change in input voltage. TheyImage may be NSFW.

tried tweaking resistor value for proper response and then we got expected results with resistor <470ohm(Finally used 100ohm and 0.1uf). Please let us know the op amp response here with high value resistor.

TLV9304: TLV9302/4 with DAC60096 or DAC43608
Part Number: TLV9304
Hi Team,
My customer would like to proceed with TLV9302/4 with DAC60096 or DAC43608.
See below:
1. DAC60096 – The output signal of DAC60096 is (-10.5v) – (+10.5v) square wave so need TLV9302/4 to amplify the signal to 0-40v square wave follow the input, does is ok?
2. DAC43608 – The output signal of DAC43608 is 0-5v or 0-3.3v square wave so need TLV9302/4 to amplify the signal to 0-40v square wave follow the input, does is ok?
What the Vcc need for the TLV930x if the amplify signal need to be 0-40v? Can you do preliminary schematic for both options?
Does TI can prepare amplify board of 256 outputs (if use TLV9304 I believe need 64 ICs) that it will connect to DAC60096EVM or can prepare amplify board of 256 outputs (64 x TLV9304) with 32 ICs of DAC43608 because TI doesn’t have EVM for DAC43608?
Thanks,
