TMS570LS0432: NPORRST Connection
Part Number:TMS570LS0432
Hi,
Im looking to use the RESET output of the TPS70445 PMIC to drive the NPORRST of the TPS570, can this be connected directly or does it need resistors or diodes in series?
Thanks,
Alex

TPS2H000-Q1: The variation of Vcs(th)
Part Number:TPS2H000-Q1
Hi,
We got a question from the customer about TPS2H000-Q1.
Could you help us?
[Question]
They want to estimate the current limit accuracy. Therefore they need the variation of Vcs(th). Could you provide it?
And let me confirm if I got it. Should they consider the following variation for estimating the current limit accuracy?
K(CL): refer to EC table (dK(CL)/K(CL))
Rlim: using resistor accuracy
Vcs(th): asking now
Best Regards,

TMS570LS 12x, 21x, 31x - ADC Enhanced Channel Selection Mode
Hi,
I'm after confirmation about what members of the TMS570 family support ADC Enhanced Channel Selection Mode.
- TRM SPNU515C for LS12x/11x Section 22.4.2.2 describes Enhanced Channel Selection Mode
- TRM SPNU499C for LS31x/21x Section 19.1 describes Multichannel conversions performed in ascending order, one channel at a time
Can you please confirm that it is only the TMS570LS12x/11x that supports ADC Enhanced Channel Mode Selection.
Regards, Tony.

BQ24230: Is it possible case to terminate charging even if battery voltage doesn't reach VBAT(REG)?
Part Number:BQ24230
Hi Team,
The electrical characteristics shows the following about VBAT(REG) and VRCH.
My customer found charging is suspended when TS pin falling to 0.3V (VHOT) and then bq24230 doesn't recharge even if TS pin is rising.
The battery voltage is 4.10V in this situation.
Is it possible case to terminate charging even if battery voltage doesn't reach VBAT(REG)?

RTOS/TDA2P-ACD: Boot-up time for SysBIOS and Linux on TDA2Px
Part Number:TDA2P-ACD
Tool/software:TI-RTOS
Hello All,
For one of project, I need to find out the boot-up time for TDA2Px device. We have two TDA2Px systems one of which will be running with SysBIOS on A15 and another will be running with Linux on A15.
In "Section 15.2 TDA2Px Device" of "SBL_UserGuide.pdf" boot-up cycles for QSPI, NOR and SD boot mode are mentioned. I am using Processor SDK 3.2.
Are these boot-cycles applicable to only for SysBIOS on A15 or Linux on A15 as well.

Abhay

BQ27220EVM-744: Unexpected waking up, data memory import and write isues
Part Number:BQ27220EVM-744
hello
I'm checking bq27220 as a coulomb counter with bqstudio, and have some unresolved issues
- My gauge waken up Immediately after reaching the current threshold, Instead of waiting for the awakening window every 20 seconds.
I have no idea way this happened. I have made sure the 'wake up comparator' is disabled.
Does the gauge have a mode that work like that? If it is a problem, what do I need to do to change this? - I can't import the '.gg' file to the 'data memory', so every time I'm working with the gauge I need to calibirate and change the 'data memory' all over again.
After pressing 'Import', click on the file and 'ok', nothing happens.
I checked that I'm in the 'full access' and 'cfg update' mode while trying this, and I press 'write all' in the memory bar, after doing all the changes and before exporting them.
How can I overcome this problem? - And one other qustion for the end,
After calibrating and changing the 'data memory', do I need to press 'write all' in the memory bar, or pressing 'exit_cfg_update_reinit' is inough?
thank you very much

BQ2002D: Single cell configuration
Part Number:BQ2002D
Hi
Our customer would like to use this device with a single NiMH battery cell. However there are mentioned at 2V on the datasheet as below.
Is that possible to use with single cell (=1.2V typ) ?
If it possible, do we need RB1 and RB2 resistor at BAT pin?

ADC3443: Interfacing with pseudo-differential sensor output
Part Number:ADC3443
Hi,
I have a pseudo-differential output from a sensor that has to be conditioned to match the input of the ADC with optimal noise performance.
The signal has the following shape :
What would be the best way to connect it to the ADC, without loosing half of the ADC range?
I considered using two op-amps to shift the common mode voltage of both signals to the one of the ADC and maybe using a differential amplifier to further refine the signal gain and common mode but I'm worried about the required accuracy for the common mode voltage shifting stage.
Do you have any recommendations for this application?
Thank you.
Best regards,
Lionel

TPS53667: IMON pin connection
Part Number:TPS53667
TPS53667 IMON pin requires RIMON and CIMON.
Are these the must components for digital current monitor? Is the floating NG?
And can we use this pin for analog current monitor by monitoring IMON pin voltage? Or should not we connect any components other than RIMON and CIMON?

TMS570LS3137-EP: Resistor value for TMS570LS3137-EP
Part Number:TMS570LS3137-EP
Our customer has noticed from one of the application note for AM3358BGCZA80-EP device ( http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist ) that the SPI signals should have a 33ohm series resistor in line.
They could not find any such recomendation for the TMS570 processor. Would you please advise whether any such measures is necessary for the SPI clocks in TMS570LS3137-EP. If required what will be the criteria to choose the resistance value?
Thanks.
