Part Number: TPS2549

When in the case of DCP mode only (1.5A), is TPS2549 have automatic ON/OFF control?

For example; when USB charging port is disconnect, customer want to change disable output without external pin control.

(EN and CTL1~3 pin are always fixed on first setting) 

Datasheet is described about DCP auto mode, but auto ON/OFF control is not described on datasheet. 

Best regards,

DLPA3005: Resonance frequency and Ripple

$

Part Number: DLPA3005

Dear TI employees,

I have 2 questions. It looks that EVM Lout/Cout parameters are different from datasheet specification.

1. DLPA3005 datasheet shows DLPA3005 design specifies resonance frequency as 15kHz. On DLP4710EVM-LC, Cout=2*22uF/Lout=1.5uH are used. The result of calculation is fRES = 19.59kHz.  Can we allow the resonance frequency?

2. Also, the ripple calculation of Cout=2*22 is VLED_RIPPLE=0.0227. The result is 3 times higher than datasheet 0.007. Can we allow the ripple?

Part Number: TMDSHVMTRPFCKIT

Tool/software: TI C / C ++ 컴파일러

Hello Dear friends, 

I recently bought the product about TMDSHVMTRPFCKIT and F2806x controlCard and PMSM,BLDC MOTOR..

but, It is suffering because it has not been implemented..

The error details are as follows.

Restarting Program Model...
Initializing target : D:\guicomposer\webapps\InstaSPIN_FOC_F2806xM\appConfig.ccxml
Connecting target: Texas Instruments XDS100v2 USB Emulator_0/C28xx
sun.org.mozilla.javascript.internal.WrappedException: Wrapped com.ti.ccstudio.scripting.environment.ScriptingException: Error connecting to the target: emulation failure occurred (<Unknown source>#14) in <Unknown source> at line number 14Restart Completed.

I used the following program.

(InstaSPIN_FOC_F2806xM)

However, it does not continue to run with the same error.

I'll attach the picture that I've compiled on the kit.

Please help me.

I unfortunately burned the same product kit. because It's the wrong way to connect..

Please help me. thank you..

TMP235: TMP235 and LM50

Part Number: TMP235

Hi,

Is it true that the only difference between TMP235 and LM50 is the voltage supply range?

The output voltage vs. temperature equation seems to be the same, and the accuracy is almost the same.

And is it true that we should promote TMP235 instead of LM50 as long as the customer is using 5V or 3.3V to power the temperature sensor?

I can't see any reason to use LM50 instead of TMP235.

66AK2H12: Navigator linking RAM

Part Number: 66AK2H12

Hi Champs,

According to data sheet (SPRS866G) table 8-1 device memory map , it has Navigator linking RAM area at physical address 0x02B0_0000 ~ 0x02BF FFFF.

If our system doesn't use Multicore Navigator , can we us this Navigator linking RAM area as normal RAM memory ?


ADS8588H: layout for the bypass capacitor

Part Number: ADS8588H

Hi

Regarding the layout guideline, the bypass capacitors of AVDD and DVDD is mounted in the bottom layer as it's mentioned at the datasheet.

I understand it's best way to place the bypass capacitor at the bottom layer when we place the bypass capacitor as possible as close to IC.

But is there any recommend layout suggestion if it can not be placed the capacitor at the bottom layer? (The parts can not be placed at the bottom layer in the customer's PCB.)

SN65C1167E: Data collision

Part Number: SN65C1167E

Dears,

Communication between boards using SN65C1167EPW.
Under certain conditions Receive abnormal data.

When I investigated it,
it was in the state of the attached file(schematic-SN65C1167EPW.jpg ).
(Abnormal data occurs when SW1 is ON.)

Below are the questions.

Q1.In the attached circuit diagram, when SW1 is ON,
What waveforms are received on 1R and 2R of IC-B.

Q2.Actual 1A and 2A became like the attached oscilloscope waveform(OscilloscopeWaveform.jpg).
Is it as expected?

When the 1D and 2D logic of IC-A is in the attached file(schematic-SN65C1167EPW.jpg ) state,

(IC-A 1D is Drive-L,IC-A 2D is Drive-H)
Pulses such as 90deg phase difference pulses continuously enter the IC-B side.
(The counter circuit after IC-B counts.)
However, if the combination is different from the attached file(schematic-SN65C1167EPW.jpg ) state,
(IC-A 1D is H,2D is H. IC-A 1D is L,2D is L. IC-A 1D is H,2D is L.)
It does not become a pulse like a 90 ° phase difference pulse.
(The counter circuit after IC-B does not count.)

Q3.Why is the attached file(schematic-SN65C1167EPW.jpg ) combination
Will continuous 90 ° phase difference pulses be output?

Best regards,
Kanetomo Nozaki

Part Number: DAC8568

Hi dear 

I have some problems with the dac8568 datasheet. 

1- what does mean the Grade A,B,C or D in the datasheet. is it an option when buying the device or a setting that we could change it?

2-what's the difference between flexible mode and static mode when we power up internal reference? in both of them we have the same options in the datasheet. it just difference in bit's we should send to shift register.

3- how can we choose synchronous or Asynchronous mode for load data?

4- what does "Update selected DAC registers" do in psge 36 of datasheet? what's the different with writing to such a Register?

5- what's the different between 3 different power down mode?

DCPA10505D: Line Regulation

Part Number: DCPA10505D

Hi Team,

I would like to see my view of power reduction in the actual case.

I'm not asking for a guaranteed value so you can rest assured.

What I would like to know is the assumed worst case value.

I would like to know the voltage at which the output power is 5V no matter how much the input voltage is below 5V.

The conditions are as follows.

 Load 35%

 Temperature condition -15 ℃ ~ 85 ℃

I think that it will be a graph like the one attached, but even if the input drops to 4.9V in this case,

5V can be maintained even in the worst case.

Best Regards,

Kenji

Part Number: CC2652R

Hi Sir,

    What is the  RSSI effective range of 1 Mbps (LE 1M) ?

    thanks.

    Ex. 

    In LE 1M, RSSI dynamic range is 70db ,and receiver sensitivity is -97dbm.

    Is the RSSI effective range between -27dbm(-97+70)~-97dbm ? 

TAS5751M: What happen between UVP and minimum recommended PVdd?

$

Part Number: TAS5751M

Hello,

Our customer try to utilize TAS5751M with x6 AAA battery.  PVdd range would be 9.0V to 5.4V.

When look at the data sheet recommended operation condition PVdd mini is 8.0V. And UVP(falling) is 5.4V, UVP(rising) is 5.8V.

Can we expect that between PVdd 8V to 5.4V area, TAS5751M D-amp is still function-able and reliable but it is not guarantied Audio performance?

Is that correct understanding?

For example, the their TAS57xx family D-amp specified that Vdd mini is 4.5V and UVP(raising) also 4.5V as TAS5719 datasheet.

This specification is simple and easy to expect function.

Regards,

Mochizuki

 

 

[TDA4M] app_single_cam camera frame output question.

Hello.

I'm copy app_single_cam and make app_single_cam_clone application for our camera sensor porting at TDA4 EVM board.

I add our sensor driver at imaging for GPIO / I2C conrtol.

Camera reset / I2C initial setting write success.

But running application Camera Image is not came out.

Q-DQ is not working and print status log there are no FPS occurs.

I have a questions below.

(1) I know app_single_cam is for IMX390 sensor.

Is it working at PSDK version 0.9 and camera image is appears at DP-port or HDMI monitor ?

(2) In the app_run_graph function, there are two Enqueue is exist.

What is differences vx_object_array at obj->cap_frames / out_capture_frames ?

Why Dequeue and Queue twice ?

tivxGraphParameterEnqueueReadyRef(obj->graph, 0, (vx_reference*)&(obj->cap_frames[buf_id]), 1, TIVX_GRAPH_PARAMETER_ENQUEUE_FLAG_PIPEUP);

vxGraphParameterEnqueueReadyRef(obj->graph, 0, (vx_reference*)&obj->cap_frames[obj->num_cap_buf-1], 1);

vxGraphParameterDequeueDoneRef(obj->graph, 0, (vx_reference*)&out_capture_frames, 1, &num_refs_capture);

vxGraphParameterEnqueueReadyRef(obj->graph, 0, (vx_reference*)&out_capture_frames, 1);

(3) This app doesn't call vxProcessGraph( ) function.

Is it doesn't need to call this function to operating ?

Jukyeong
