Part Number:TPS7B7701-Q1

Hi ,

For TPS7B7701QPWPRQ1 , for short to battery condition , the output of current sense voltage remains low . Whereas , when there is short to Ground condition ,the output of current sense voltage is 2.55V .

Please let me know why it doesn't work for short to battery condition.

Part Number:AM4376

Tool/software: Linux

Hi SIr

We used AM4376 with DP83867IR for design and add external module in the MB,

we assume the harmonic of DP83867IR CLK(25MHz) impacts to module's 1575MHz.after doing some exerpiments

Does AM4376 support power control register for RGMII(TX, RX) and TDX ? or is there SSCG function in AM4376?

LM27762: How much current can the PGOOD pin safely sink?

$

Part Number:LM27762

I would like to directly drive an LED, if possible, at about 1mA when the regulator outputs are operating normally. e.g. wiring +12V through 10K to the LED anode and then connecting the LED cathode to the PGOOD pin of the LM27762. Will this be OK or do I need to add something else to drive the LED instead? (e.g. base/gate of transistor)

Part Number:CC3220

Dear, Experts.

1. If you have test data between CC3220SF and various APs, can you share it?
   because, I would like to know about the proven AP List.
2. There was a problem that TCP Socket was disconnected and reconnected while communicating with a specific AP.
    At this time, the firmware of the AP is updated and the phenomenon disappears.
    There are a variety of causes, but what are the big things that you can suspect & Opinion?
Please Help & Review.
Thank you

Part Number:TPS61021A

Hello,

My cosutomer is wondering what the accuracy of VREF is at the FB pin in PFM mode. I saw a similar question posted earlier last year on this topic for the foloowing condition:

 - measurement conditions

 ・Input voltage   1.8 V to 3.2 V
 ・Output voltage   3.3 V

Link: 

Does the 775mV to 825mV apply for all input and output conditions or just the ones Seishin asked about?

Thanks,

John

Part Number:ADS114S08

1) We need to configure ADS114s08 in bipolar input(+/-2.5) with inbuilt PGA. How to configure for REFOUT, REFCOM, REFP0 & REFN0. Also what should be software register settings.

2) Also we tried to generate internal +2.5V at REFOUT and -2.5V at REFCOM by configuring REFSEL[1:0] = 10 REFCON[1:0] = 10. But +2.5V was not measured at REFOUT pin and -2.5V was not generated at REFCOM pin.

DS90UB954-Q1: Sync Mode Question

Part Number:DS90UB954-Q1

Hi Expert,

953+954 with Sync mode, it can display 4MP/30fp imagers. If the CMOM I/F is DVP and 2MP, the solution should be 933. 933 didn't support Sync mode and the line rate support 1.9Gbps, 1.2Gbps video.

If we use 933+954, does it possible to display 2MP/60fp data? Thanks!

Part Number:TMS570LS3137

Hello QJ,

One of customer has the following requirements,

Unfortunately, the FMEDA v.1.0 for the RM48x can not be found, because this is updated.

I basically only see:

SPNU527C - Detailed Safety Analysis Report for RM48x v.1.2 as ZIP file. The corresponding FMEDA v.1.0 is not available for us.

TÜV Süd demands additional documents from us:

-          Category 3 (Cat.3) FMEA (ISO-13849)

-          IP Core FMEAs

Can you please provide the requested documents for my customer.

Thanks,

DRA75: Adding IPC to RTOS examples

Part Number:DRA75

Hi,

I am trying to add IPC to the MyExampleProjects created on running ./pdkProjectCreate.sh. This is done so that I can add the resource table and create an executable by building the example in CCS. I have followed the steps from the link  in which i'm trying to add IPC to IPU. The example I have tried to build is I2C_BasicExample_evmDRA75x_m4ExampleProject by including the procedures mentioned in the link but the CCS comes up with build errors. What might be the issue ? I have skipped the UART portions explained in the link since its not useful for this example.

HD3SS3220: USB3.0 Hub Connection Issues

Part Number:HD3SS3220

Hi Ti,

           

If we are going to use this part from TI, would the TX/RX be swapped on both sides or one side? Why it is swapped on HUB but not on MUX or splitter? We've checked that if we connect module USB to hub, then we should connect TX to TX, RX to RX, and the other side of the hub which connect to MCU should connect to TX to RX, RX to TX.

The above is just said that you should swapped two side of HUB, just need to swap the side that connect to MCU side. Is this correct?

BQ76PL455A-Q1: Unable to Read Device Addresses in Daisy Chain Architecture

$

Part Number:BQ76PL455A-Q1

Hello All,

I am working on 2 bq76pl455a-q1 stacked configuration. Single IC works perfectly well by reading Voltages, Temperatures, Faults and balancing.

Now I am trying to interface 2 IC on the same PCB board. Both the IC have been waken up with VP,Vio voltages 5.3V with respect to local ground.

When using auto addressing method for addressing the bq76pl455a-q1, base board ID ids written 0 and Top board ID is written 1. While reading back device addresses, both base board and Top board reads 0.

So, i have a doubt in either Firmware code or Hardware design. But hardware design seems to be OK as TOP board gets waken up through Wake up tone on COMM+- lines.

I am attaching my initialization code below. Please let me know if i am missing out something.

nDev_ID = 0;
nSent = WriteReg(nDev_ID, COMCONFIG, 0x10E0, 2, FRMWRT_ALL_NR);    // set communications baud rate as 250KBaud

nSent = WriteReg(nDev_ID, DEVCONFIG, 0x19, 1, FRMWRT_ALL_NR);

nSent = WriteReg(nDev_ID, DEV_CTRL, 0x08, 1, FRMWRT_ALL_NR);			// Auto Address enable

uint8_t wTemp, wTemp1;
	// Set addresses for all boards in daisy-chain (section 1.2.3)
	for (nDev_ID = 0; nDev_ID < TOTALBOARDS; nDev_ID++)
	{
		nSent = WriteReg(nDev_ID, ADDR, nDev_ID, 1, FRMWRT_ALL_NR); // send address to each board
	}
	
// read device ID to see if there is a response
nDev_ID = 0;
nRead = ReadReg(nDev_ID, ADDR, &wTemp, 1, 0); // 0ms timeout
printf("Device id 0 : %d\r\n", wTemp);
	
nDev_ID = 1;
nRead = ReadReg(nDev_ID, ADDR, &wTemp1, 1, 0); // 0ms timeout
printf("Device id 1 : %d\r\n", wTemp1);

nDev_ID = 1;
nSent = WriteReg(nDev_ID, COMCONFIG, 0x1020, 2, FRMWRT_SGL_NR);	   // enable only comm-low for the top board
	
nDev_ID = 0;
nSent = WriteReg(nDev_ID, COMCONFIG, 0x10C0, 2, FRMWRT_SGL_NR);	   // enable comm-high, single-end comm port on bottom board

Thanks

Part Number:AWR1642BOOST

Hello

1) We are using AWR1642 for short range configuration

Scenario A :  Object(RCS of an adult) is placed  at a height of 1.5 m and radar is placed approx at a height of 1  , radar detects the object .

Scenario B :   Object(RCS of an adult) is placed  on the ground and radar is placed approx at a height of 1 m , radar does not detect the object .

We want to know the z coordinate coverage at a distance of 1.5 m from the radar .

2) In short range radar configuration , could you provide the details of the Tx and Rx beam width  and information on side lobes.

Will these parameters change when the profile is changed .

IWR1443BOOST: Interface with external MCU

Part Number:IWR1443BOOST

Hello,

I am new to IWR1443 sensor and my application is a fluid level measurement. I am trying to interface IWR1443BOOST with another MCU (similar to Arduino). I am confused on how to proceed solving this. My questions are:

1. After every power cycle does the BOOST board requires writing of Config file to make it start sending the data? If true another MCU can be made to send this data.

2. I can parse the UART output data in the MCU as given in this post  .

Is my understanding of the problem correct? Is there a much simpler way to get the range data to an external MCU?

Regards,

Prudhvi Sagar

BQ25601: AC adaptor violates VAC OV of bq25601

Part Number:BQ25601

Hi

Using AC adaptor voltages (10.5V) violates the default of VAC OV (min 6.1V).

MCU’s power is sys side. So it happens never wake up charge.

To avoid it, is it OK bellows connection ( Vsens is divieded by resistance from VBUS)?

UCC28951-Q1: UCC28951-Q1- not getting pwm from control IC

$

Part Number:UCC28951-Q1

Hello 

1. What are the minimum conditions to obtain PWM on pins 17-22?

2. I am doing an experiment on this IC and let me explain the setup. I am giving PWM to full bridge inverters by using microcontroller and gate drivers so that I can vary DUTY CYCLE. On the secondary side of the transformer I have placed full bridge diodes instead of Syn Rectifiers for easier understanding. Later I give the main feedback signals of VOUT and Input current via Current sense transformer. Atleast I am expecting PWM on all the pins (17-22). But I observe PWM only on pins 19-22 with 50% duty cycle. The output voltage is well within the design range. Where am I going wrong?

3. Will I get PWMs if I give DC less than 2V on CS channel (pin 15) provided I have given DC less than 2.5V on pin 3?
