hello
we have designing Dual Port Automotive USB Charge Port .but we are using TPS2513A-Q1 and TPS2561-Q1 . in this configuration design output voltage is drop. (2A load voltage drop)
is there is any difference between TPS2561-Q1 and TPS2561A-Q1
some difference found TPS2561A-Q1 ( Accurate 2.1A Min / 2.5A Max Setting)
Part Number:WL1807MOD
Dear all,
During the laboratory tests to check the compliance of our device integrating the WL1807MOD with the RED directive, we used the calibrator software, as described in "WL18xx_TX_Testing" document and we had to set the tx power with the command
calibrator wlan0 wl18xx_plt set_tx_power 10500 0 0 1 0 0 0 1 0 0 0 0
The power in this way was set to 10.5dbm in order to be compliant with the standard.
Now it's not clear to me what are the parameters to change in .ini file in order to have the same power limitation set during the test also in normal operation.
Someone can help me?
Best regards

I need such a device - 3.3v input tolerable while powered by 2.5v but with 10 outputs and not just one.
Part Number:TMDSHVMTRPFCKIT
Hi,
The test bench set-up for our motor control activities are realized with TI High Voltage Motor Control and PFC Developer's Kit (TMDSHVMTRPFCKIT) and TMS320F28035 MCU. The Motor used is PMSM from ESTUN motors - EMJ-04APB22. Our area of interest is the FOC speed control of the PMSM motor.
We are trying to run the motor using example projects available in the mathworks website. The program, we use to flash is 'c28035pmsmfochvkit_ert' available in the following link.
Part Number:IWR1443BOOST
Hi,
We want to develop a people tracking application using the mmWave sensors available.
This involves dividing an area into different zones and calculating the time each person spends in a particular zone.
Zone detection or people counting, which is better suited for the application?
And also is there any pre-built demo for calculation of time?
Which sensor is better suited for this application?
Regards,
Prabanj
Hi Ti,
We are evaluating different wireless technologies (which support Mesh network) and different manufacturer for same.
Our application is low power so want to develop solution with SoC instead of using ready module.
Solution will deploy in floor area of industries so noisy environment, Range is not that much matter (20-50 meter will be fine in PoC, we can tune Antenna for further).
To narrow down my search result, I would like to directly ask that does TI has relevant solution for that? please suggest SoC for that, Also It should be licence free band. Also advise its EVM if available.
Thanks in advance for your support.

Hi All!
I've found bug in Keystone II PCIe driver. Looking at the function ks_pcie_setup_mem_space (drivers/pci/dwc/pci-keystone.c:601 in PSDK 05.01.00.11):
val = ilog2(OB_WIN_SIZE);
ks_pcie_app_writel(ks_pcie, OB_SIZE, val);
/* Using Direct 1:1 mapping of RC <-> PCI memory space */
for (i = 0; i < num_ob_windows && (start < end); i++) {
ks_pcie_app_writel(ks_pcie, OB_OFFSET_INDEX(i),
lower_32_bits(start) | OB_ENABLEN);
ks_pcie_app_writel(ks_pcie, OB_OFFSET_HI(i),
upper_32_bits(start));
start += OB_WIN_SIZE;
}
Here OB_WIN_SIZE is declared as 8, so outbound index start address is incremented by 8 instead of 8M.
Consider following patch:

Part Number:MSP430F5659
Hi Team,
We are working on a custom board (second revision) with MSP430F5659. As per the flowchart in page 3 of slaa452c.pdf, when PUR pin it pulled high when Reset is pressed with the presence of VBUS, USB BSL is invoked.
But, we are seeing some different scenario in USB BSL invoke:
Case 1: By default, VBUS will not be available. VBUS is controlled through a switch, VBUS is available after 500ms of Reset is held low and Rest is released after 500ms. We have a 120E pull-up resistor at PUR pin to VUSB. In this case, USB is not getting recognized at the Host.
We also tried by connecting the device to Windows PC. The USB cable is plugged to PC while the reset switch is pressed. Still USB is not getting recognized at the Host.
Case 2: When the USB is getting enumerated, when we press the Reset switch, USB is still enumerated and once we release the switch, USB gets disconnected and USB is not getting recognized at Device Manager.
Case 3: We are controlling the BSL sequence from the Host processor. PUR pin is controlled by the GPIO of Host Processor present in separate board. In this case, there is no external PUR pull-up resistor present on the board. This GPIO signals travel from the Host Processor to MSP430 via a cable assembly of length 200mm. Hence, we have a ESD component TPD6E05U06RVZ near the MSP430 end.Even if the PUR is pulled up by the GPIO of Host Processor, USB is not recognized. We tried after removing the ESD component and disconnected the Cable then tried the Case 4 below.
Case 4: When VBUS 5V is made available in default and USB cable is connected to Windows PC even without pressing reset, USB is getting enumerated even without PUR pulled High externally. MSP430 is powered from 3V3 LDO and 5V is provided from switcher on board, both powered from external 12V supply. There is approximately 750ms delay between 3V3 generation and 5V generation. As per the recommendations, we have 2M weak pull down at PUR pin and when probed, PUR pin detected to be low. I am not sure how the USB is getting detected in this case.
Are we missing anything here? Have anyone faced similar issue and please let us know to fix this issue.
What modification to the circuit do you suggest?
Part Number:TLV320DAC3203
Hello.
We chose TLV320DAC3203 for high-resolution applications (24bit-96KHz sample rate, need good frequency response at 20~40Khz) but encountered some problems on EVM.
The EVM Line in input capacitor reference is recommended to be placed at 0.1uF, and the frequency response is very poor (-3dB points are more than 200HZ).
Changed to 1uF, the situation improved, but still not good enough, we hope that the target is at least -3dB point at 20HZ, currently added to 4.4uF, there is also 5dB attenuation at 20Hz.
Normally, the audio codec line in should have high impedance (the actual measured EVM input impedance is close to 70K ohm), Theoretically the input capacitor should not need to be added to such to high.
Please help suggest if there is a better way to Improve results.
In addition, the output capacitor EVM is 47uF, we increase it to 220uF, the BT I2S output low frequency response is not OK, and later adjusted to 440uF is closer to our demand,
but the 440uF MLCC capacitor is very large and very expensive (we can not consider Solid capacitor),
If need to put such a large capacitor, the price advantage of this codec no longer exists...
Is it necessary to replace the codec with cap free? Thanks for kindly help~

Part Number:TLC5951
Hi,
I'm trying to use TLC5951 with AMPMAFB-33.0000 MEMS oscillator for Grayscale PWM clock signals, connected to GSCKR/G/B in parallel. As soon as the oscillator is connected to the TLC's pins, the clock signal breaks down, recovering after opening the connection again. So I wonder if the input pin's capacitances might be too high. Could you tell me the capacitances of GSCKR/G/B pins? In the datasheet it's only stated that the input current is maximum 1µA.
If this doesn't lead to a solution, do you recommend any spedcific oscillator IC to be used with the TLC?
Thank you very much for the support.
Best regards,
Tino

Part Number:DLP9000
Hi, I have two questions regarding controls of multiple DMD boards (i.e. Lightcrafter DLP6500 or Lightcrafter DLP9000)
(1) Can I use DLP Lightcrafter GUI to control more than one DMD separately using a single computer?
(2) I am using a MATLAB code based on Programmer's Guide Manual to control a single DMD in a pre-stored mode. If (1) is possible, can I control more than one DLP Lightcrafter using a MATLAB code?
Part Number:TIDA-00056
Hi,
I am using Gas Sensor Platform with Bluetooth Low Energy (LMP91000 with CC2541). I found a project called SensorBLEPeripheral that supports both CO and O2 sensors. My problem is that I couldn't change Vbias value using the existed source code. There is a file called CO_Sensor_Settings.h where I have access to these macros:
// LMP91000 Settings for the CO Sensor #define SENS_OPERATIONAL_MODE OP_MODE_3_LEAD #define SENS_FEEDBACK_GAIN TIA_GAIN_7K_OHM #define SENS_RLOAD R_LOAD_10_OHM #define SENS_INT_Z_REF_DIVIDER INT_Z_SEL_20_PERCENT #define SENS_REF_SOURCE REF_SOURCE_EXTERNAL
if (!LMP91000_I2CWriteAndConfirmReg(LMP91000_I2C_Address, TI_LMP91000_REFCN_REG, (ref_source | internal_zero | BIAS_0_PERCENT | BIAS_SIGN_POSITIVE)))
As the question above, what are techniques that ePWM is able to provide in terms of PWM e.g. bipolar, unipolar, so on.
Thanks all.
Part Number:LMK04133
HI
I am not sure how to terminate the LVCMOS clock output from the lmk04133.
I need to connect it to a 50 ohm sma connector.
Do I just connect it with a 50 ohm pcb trace or do I need a resistor and/or capacitor to gnd?
If so, I guess the resistor should be 50 ohm, but I don't know about the capacitor. The clock frequency will be between 75 MHz up to 320MHz
