Part Number: TPA3221
What is the reason why TPA3221 cannot enter the overheat protection?
Can pins 3 and 4 of TPA3221 be powered by an external 5V resistance of 47K?
Is it correct that TPA3221 pins 3 and 4 supply power through AVDD voltage 5V of 21 pins inside IC and through 47K resistance?
(Please visit the site to view this file)TPA3221 cannot enter the overtemperature protection, resulting in the product burning IC at full power output after 1-2 hours. What is the reason?

Hello :
This is a car pmsm controller problem.
I need to design a permanent magnet synchronous motor controller that is used on low speed cars. The system is powered by a 72V battery, and the controlled motor is a 15KW permanent magnet synchronous motor. This current is as high as 200A+.
Can you provide samples for reference, including hardware schematics and software source code, thank you!
Part Number: TPS62840
Greetings:
Could you explain what is TPS62840 DCS control and how could it work on power saving mode?
Are there any other TI low power production introduce to me? I'm evaluating power solution of low power IoT project.

Hi,
I would like to know the gauging can work from -20 degree C.
Is the gauging accuracy change if the temperature is -20 degree C (can it achieve same performance as room temperature?) I guess algorithm has Rb table and support lower temperature but I would like to know if it support from -20 degree C.
Regards,
Nagata.

Part Number: TPS61196
The TPS61196 does not work. The schematic like this. We never make it to the point where the buck converter turns on (never saw a single pulse on the gate of Q1). The Boost switcher can not turn on and the output voltage(VCC_LED) before the Boost switcher turns on is around 23V (24V -diode drop). The LEDs are on a different board where we terminate each LED string (16 of them) with a 10M to ground, Each string is composed 16 LEDs. The voltage drop across each LED is 3V.
i remember TI has a software for desktop. after installation, it will show all the TI hardware products according to the types. e.g MCU, power regulator and etc. what is the software name and where to download it?

Hello,
I'd like to know Safety Diagnostic function on my HALCoGen-generated code(Ver.04.07.01, TMS570LC4357ZWT project).
Does these code contain Safety Diagnostic function?
Otherwise, Should I need to use SafeTI Diagnostics Library?
Sincerely yours,

Hi team.
I'd like to know about current on FAULT pins.
According to data sheet at absolute maximum ratings, it write -30~10mA.
What is the meaning of -30mA ?
I think that 10mA is the sink current value.
I'm thinking about deciding on pull-up resistance.
Sincerely.
Kengo.

Hi,
IQ data are saved to address 'RFC_RAM_BASE + 0x0000C000' in function AOA_getRxIQ of AOA.c.
Would some one explain why samples are saved to 0x0000C000 offset of RFC_RAM_BASE? Is there any explanation in datasheet?
If more antenna groups are used, i.e. 4*2 or 6*2 antenna, should I store to same address? Is there enough space for storage if sample data increase?
Thanks a lot.

Part Number: UCC28180
Hello
I have a question about UCC28180.
Question 1
The PFC (UCC 28180) was turned off from the on state using the measurement power supply. At this time, the potential of the following terminals of UCC28180 is temporarily reversed.
Do you need any measures in this situation?
Also, if it is necessary to take measures, is it better to connect a diode from VSENSEpin to VCCpin?
<On the potential>
・ Measurement power ON state: VCC> V SENSE
? When switching the measurement power supply from ON to OFF: VCC <VSENSE
Thank you.

Hi Team,
We want to know the possibilities of DSP ROM code update from an external processor via UART or I2C.
We are not using the SD interface or USB interface of DSP in our project.

Hello
I have a question about LM5039.
The AC / DC controller (LM 5039) was turned off from the on state using the measurement power supply. At this time, the following terminals of the LM5039 temporarily reverse the potential.
Do you need any measures in this situation?
Also, if it is necessary to take measures, can we connect diodes from RAMPpin and UVLOpin to VCCpin respectively?
<Relationship of potential>
・ Measurement power ON state: VCC, VIN> RAMP
・ When switching the measurement power supply from ON to OFF: VCC, VIN> RAMP
・ Measurement power ON state: VCC, VIN> UVLO
・ When switching the power supply for measurement from ON to OFF: VCC, VIN> UVLO
☆ 1 VCC and VIN terminals are shorted
Thank you.

Hello,
We are developing a SDR platform based on AM5718 with audio codec TLV320AIC3106.
Since it is an SDR platform,we have to switch waveform at runtime. My query is related to Linux platform device driver.
My understanding is that once powered up, Linux platform device driver will configure the audio codec to a default state.
I have few queries related to it, is it feasible to:

Hi,
The AM3892 Datasheet specifies that the resistance of the HDMI_EXTSWING line should be 6.8 kohm.
But, the EVM Board is connected at 5.9 kohm.
Please let me know which is correct.

Hi Harrison,
preTIDA-01093 Sample Source Code and Resource Firmware
I do not think this code is available. There are multiple changes that would be needed for the 20S reference design - the MCU needs to communicate with each BQ76930 device one at a time.
I will check with the team that did this project to see if it is possible to share the firmware. It may take a couple of days, but I will let you know.
Best regards,
