CCS/BQ76PL455A-Q1: Trouble parsing include or instance XML file
Part Number:BQ76PL455A-Q1
Tool/software: Code Composer Studio
Hello,
I thank you heartfully I got the answer to my question and now I even know those functions. This is my last question regarding this I am getting an error when building the code.
The error is :
Trouble parsing include or instance XML file
C:\ti\ccsv7\ccs_base\common\targetdb\..\Modules\hercules\CP15_CortexR4F_r1p3.xml (The system cannot find the path specified)
How can I fix this? I have searched all the folders for that file that doesn't work...
Hope I get an answer to this question too...
Thank you.

BQ76PL536A-Q1: Too high sleep current consumption.
Part Number:BQ76PL536A-Q1
Hello
I built a prototype with BQ76PL536A-Q1. Everything works good, except sleep current. In the datasheet is written the sleep current value max 22uA. When I set IO_CONTROL[SLEEP] = 1 current consumption is 400uA.
Here is my initialization :
reg_write(BROADCAST_ADR, RESET, 0xA5); //broadcast reset
reg_write(BROADCAST_ADR, SHDW_CRTL, 0x27); //enable write to group3
reg_write(0x00, ADDRESS_CONTROL, 0x01); //set address
reg_write(0x01, CB_TIME, time_sec_max_63 & 0x3F); //set balance timer
reg_write(0x01,ADC_CONTROL,0x45); //set number of cell
reg_write(0x01, IO_CONTROL,0x04); //sleep
schematic is in attachment.
Can you help me with this problem?

BQ27510-G3: Is the Board Offset calibration really necessary?
Part Number:BQ27510-G3
Hello,
i am just preparing the automatic testing and programming of series production of our boards with BQ27510.
The GoldenImage is well created as prescribed and I'm not sure if there should be a calibration of the Board Offset for every single board during the testing process.
I have understood that the CC-Offset is calibrated automatically.
What would you recommend? What makes really sense?
Best regards
Markus

TPS783: TPS783: EN pin using
Part Number:TPS783
Hello.
I have a problem. The TPS783 has EN pin, what i can use if i want to shut down the IC (so it does not give voltage). My problem is if i take 0 to EN pin, the IC give me 3,3V and same problem if take 1.
So my question is what is the problem? Maybe there is software settings or only the hardver is wrong.
Thanks the help.

TLC5940: Python Library for TLC5940 on Raspberry Pi?
Part Number:TLC5940
Hello,
Is there a TI-maintained Python library available for interacting with the TLC5940 chip? I'm especially interested in Python libraries that allow Raspberry Pis to interact with the TLC5940.
I found at least two libraries on Github:
1) https://github.com/AidanHolmes/tlc5940
2) https://github.com/lrvdijk/tlc5940-raspberry
Which does TI recommend?
Thank you

LP5018: PLP5018RSMR v.s. LP5018RSMR
Part Number:LP5018
Dear Team,
Is there any difference between two-part number? (PLP5018RSMR v.s. LP5018RSMR)
Originally, the customer use PLP5018RSMR, but I can't find this part any more.

TPS40170: HDRV and LDRV of TPS40170 are no working
Part Number:TPS40170
Hi,
I am designing a 5V and 4V output with 3A power suplly with the TPS40170. I have a protoytpe now where the VBP and VDD can be measured but i can´t switch the MOSFET, because not switching signal on LDRV and HDRV, what could be the problem? I measurde all the voltage and they are in the range.
Thanks

TLC5947: What is the purpose of the Zener diode in PMOS line scan circuit?
Part Number:TLC5947
Hi,
I want to design a 15x15 LED matrix by TLC5947 in Vled 3.3V.
My question is what is the purpose of the zener diode (in TIDA-01615 reference design and TLC5957 datasheet)?
and how to decide the spec in different Vled? in my case is 3.3V.
Thank you.

TIDM-THREEPHASEMETER-F6779 Calibration issue
Hi,
I am using TIDM-THREEPHASEMETER-F6779 3 phase energy measurement reference design and added extra circuits. I need to measure 3phase voltage,current and power
For one of my application, i am using 3 numbers 12V step down transformer to measure the 3phase voltages. I am using these transformer mainly to isolate the high voltage from my board. For current measurement, i am using 3 current transformers. With this set up, when i do calibration using GUI application, i get wrong value of output voltage. Voltage reads correctly 13.5V when not calibrated. I just want that instead of 13V, it should show 230V. Since the number of turns is fixed in transformer, so i think it should give be possible to do such calibration. My application doesn't require exact measurement and +/-5V difference is acceptable.
I want to know if it is possible to do such calibration. When i try to do such calibration, and read the calibration factor, it shows negative value and after that when i try to change the calibration value it doesn't change at all.

TPS259824OEVM: Different question
Part Number:TPS259824OEVM
Hello,
I have questions about the TPS25982 component.
First, does it exist any calcul to define the delay between two retry ( For the "RETRY_DLY" capacitor)?
And have you a formula too define the number of retry ? In the specification, it's not clear.
My last question is about the product status and when will it be available?
Thanks

LM2775-Q1: Output Capacitance + 8.2.2.5 Note
Part Number:LM2775-Q1
Hi,
I have a customer using LM2775-Q1 with output capacitance of 2.2uF, 25V. I wanted to check if that was enough, as a rule of thumb, and ran across a note in 8.2.2.5 that confused me, below:
My question is what is the 2-uF capacitance it recommends in my highlighted seciton? Is that saying to increase the flying capacitor to 2-uF or decrease the output capacitor to 2uF? It isnt clear to me. They have PFM enabled so I wanted to make sure I am interpreting the note correctly.

Kevin

BQ78350-R1: Questions about cell balance (Follow-up thread)
Part Number:BQ78350-R1
Greetings!
In the video linked below, At 3:15. There is an explanation concerning balance with voltage separation. It is said that cell balancing starts when at least one cell is below the Cell balancing Threshold Min (Vstart) and another cell is above the Cell balance Threshold(VCBT). It is also said that the cell balance stops when none of the cells is below Vstart. To continue the cell balancing one cell must exceed the new threshold (incremented by Cell threshold Min).
Why does one cell have to exceed the next cell balance threshold (4000 mV) to let the cell balancing continue? Why does it not even the cells voltage out among the cells until the difference between the cells is equal to the cell balance min?
Am I missing something here?
For a concrete example: The cell balance threshold is at 3900 mV, the cell balance window is 100 mV, cell balance min is 20 mV and a charge current of 50 mA.
If one cell is charged above the cell balance threshold (3900 mV) and the other cells are below Cell balancing Threshold Min (in this case 3900-100 mV) the balance will occur until the cells are above the Cell balancing Threshold Min then it stops. In my opinion, it should continue balancing until the difference between the cells is equal to the cell balance min (in this case 20 mV).

Best regards,
Michael.

BQ20Z655-R1: LFP Support
Part Number:BQ20Z655-R1
Hi ,
If it is possible, I would like to use LFP (LiFePO4) cells with BQ20z655-R1 . Is there any way for that such as ChemID etc. ?
Thank you.

BQ76930: Cell Balancing and Discharge Driver not working
Part Number:BQ76930
I am using a BQ7693006DBTR (no CRC) as an AFE for a 6s Li-Ion battery pack.
Although cell voltages read correctly, I am not able to activate any balancing circuit.
A few random remarks (not sure what is relevant):
- the cells are connected as recommended in the datasheet (Table 8-2)
- balancing should be achieved through an external N-channel balancing network like described in the Design Recommentations (Figure 6)
- the balancing network works as expected when shorting the respective cell input pins (bypassing the internal balancing FET)
- no fault is active in SYS_STAT
- ADC is enabled (Bit 4 in SYS_CTRL1), CC is disabled (Bits 5-6 in SYS_CTRL2)
- cell balancing bits (CBx in CELLBAL registers) read back as intended after writing
- activating the CHG FETs work, activating the DSG FETs doesn't work (DSG_ON in SYS_CTRL2 reads back as '1', though)
- load detection circuit works (LOAD_PRESENT in SYS_CTRL1)
Since both balancing and activating the discharge circuit don't seem to work, I suppose I've missed deactivating some kind of protection circuit, although I can't find any reference to anything similar anywhere.
What am I missing?
Kind Regards
Lasse
