Design requirement:
Input voltage: 85 to 240VAC(50-60Hz)
load current max 2.5A(RMS)
Please help!

Hi,
I'm looking to power and control the dimming for an AMOLED display, and was looking for help in how to connect the power and dimming of the amoled. To my understanding, AMOLED displays don't have a backlight, so it's not possible to change the brightness of the actual display. Instead, you can change the voltage/current or the duty cycle of the power to the display to change the brightness.
I'm planning on using an STM32 processor and getting power from USB-C connected to a computer or laptop. I believe that I need a display bias PMIC as a power supply for the display, but I'm not sure how/what dimming solution fits into the circuit.
There's two different types of dimming for OLED: DC dimming and PWM, and I would prefer to use DC dimming, but if it's not possible PWM is fine as well.
For PWM, do I simply connect the output of the display bias to a transistor and change the duty cycle to change the brightness of the display?
If there was any recommendations for chips to use and their circuit configurations that would be greatly appreciated.
Thanks!

Hi Team!
In one of the applications, I am using TLE4476D operating both channels sourcing 100mA. While operating the IC at room temperature IC heats up to 70 degrees Celcius. When I test the IC at 60 degrees Celsius, IC starts to shut down and power on repeatedly, to be specific it shutdown every 2 Sec for the duration of the 500mS to 1S.
The same thing is observed in the TLE4267GM IC testing with the same environmental conditions. The output current is 100mA while testing.
Kindly tell me the reason for this happening. It will be great if you can provide me with a solution for the same.
I am applying 28.5V at the input of the IC.

お客様はIRS2109Sから2ED2109S06Fへ置き換えを検討しています。
1.
2ED2109S06Fに関して、INとSDのInternal Pull-up/Pull-downの値を教えて下さい。
2.
2ED2109S06F Datasheetのp4のBlock Diagramでは、SDは+5VにPull-upされています。
この+5VとはVccのことですか?
もし、Vcc=12Vであれば、内部で12VにPull-upされますか?
お手数ですが、ご回答宜しくお願いします。
Show LessI understand that to configure WWD, set the 0x06~0x0A register after trigger in LOW.
Although WWD has been implemented in the system, I am inquiring because it sometimes starts with an increase in Err Cnt in the initial drive.
Does changing the value of the WWD register restart the LOW? Or does CWOW continue with the changed value?
I would like to know which state (INIT, NORMAL) and at which point it is advantageous to change the setting of the WWD.
In the currently configured system, the symptoms are as follows.
1. Trigger at LOW (Initial setting 600ms)
2. Set up WWD-related registers in Protection Registers.
3. Trigger accordingly with the thought that the CW & OW changed to the setting value will continue.
If no. 2 is performed only once, the ERR CNT rises to 2 once, and then the correct trigger gradually continues to converge to 0.
If no. 2 is performed several times (less than 10 times at 10 ms TASK), it operates without increasing ERR CNT.
Hi,
I am working on bringing up a custom board. We have a lot of experience with the IMC101TF048XUMA1 and have integrated this into our design. I am using a iMotion-Link to attach a PC to the board for programming. I am trying to establish the initial communications and to program the initial Firmware onto the IMC101TF048XUMA1.
I can see the UART signals (0-5V) arrive at RX0, pin 45 on this part, but there is no response.
I have also verified on an oscilloscope that the signal is as expected. It arrives at the pin with clean transitions, and I used the same 'scope to verify the UART signal as a series of 4 bytes from MCEDesigner - as you can see on the plot below. Here you can see the incoming signal on the bottom trace. Of course, to look for the response I also zoomed out and looked to the right and found no response from the TX0 pin 46, nor did the MCEDesigner app connected to the port.
One thing I did notice is that the pulses measure at an equivalent of 113.2kBaud rather than 115.2kBaud. This is what the iMotion-Link generates. Is this enough to cause the signal to be rejected by the IMC101?
Any thoughts on any reason why the device might not respond to this signal?
Here's a schematic snippet for reference. We are using 5V for power, and power is applied to the board.

Hi,
I am looking for a mosfet which would be appropriate for essentially DC switching of a 400V 7A continuous load. Low RDS on is preferred as I have limited ability to remove heat easily.

I am designing a peltier controller, I will use a MOSFET h-bridge for this.
I have been reviewing many data sheets and I have a doubt, I don't know which of these gate drivers to use.
These are the options I would like to use:
a.- 2ED2103S06F
b.- WCDSC006.
I will place 4 N-MOSFET, IRF40R207, on the h-bridge.
I will use a microcontroller from the XMC1400 family that works with 5V for the PWM and the PWM will have a frequency of 5KHz, and calculate that I need a gate resistance of approximately 80 Ohms. I want to use a 12V power supply with the 2ED2103S06F, but I'm not sure if it will turn on the MOSFET fast enough running at 5KHz (it's a relatively low frequency but it's the first time I've worked with infineon's drivers) or maybe it would be better use a WCDSC006 and use a 5V supply, but according to the graph of the IRF40R207 it can handle approximately 12A with a VG of 5V, but the pelier cell that I will use consumes 8.2A and I do not think it is good that the mosfet controls a very close maximum current to the load current.
thanks for your help
Hello,
I'm writing code for communicating with a TLD7002 for a development tool, and would like to ask a few questions concerning the calculation of the CRC sums. As the driver library is not yet available to me, I'm implementing basic access to the HSLI in the programming language I'm using.
The datasheet of the TLD7002-16ES specifies two types of CRC algorithms, a 3-bit CRC, and an 8-bit CRC.
1. Regarding the 3-bit CRC, in the software design training video there appears a step where the crc value is reflected (mirrored) after processing the first 5 bits:
/* get reflected CRC3 value */
crc = TLD7002_MIRROR_MID_CRC3[crc];
I cannot find this step in the datasheet on page 67, though — an extra step reflecting the crc value after the first 5 bits and the tail 8 bits is not mentioned there; is the datasheet correct regarding the calculation of the 3-bit CRC?
2. The CRC-8 is defined as using the generator polynomial "0x8e = x^8 +x^4 +x^3 +x^2 +1" from CRC-8-AUTOSAR and SAE J1850.
But, from my understanding, 0x8E — binary: (1)-1000-1110 — actually is not the same as x⁸ + x⁴ + x³ + x² + 1;
0x8E is the reversed — LSB-first — form of 0x71 (1)-0111-0001, which corresponds to the polynomial x⁸ + x⁶ + x⁵ + x⁴ + 1, and is the reciprocal form, or Koopman representation, of the CRC-8-SAE polynomial 0x1D, but with similar properties:
(Source: Wikipedia)
So if the polynomial actually is 0x8E, then for calculating the CRC-8 of the safety byte the reversed, LSB first, algorithm would have to be used. Is this correct?
If yes, then this possibly also applies to the CRC-3, because two CRC sums used in the same HSLI frame are likely implemented in the same fashion. This could mean that the polynomial to be used when calculating the CRC-3 would be 0x6 ("reversed"), or 0x5 ("reversed reciprocal"), but not 0x3. Which one is actually used by the TLD7002-16ES?
The CRC-8 of SAEJ1850, by the way, also defines a final XOR step, where 0xFF is XOR'ed into the crc value. I suppose, since the datasheet of the TLD7002-16ES does not mention this, this final step of the original SAEJ1850 definition does not need to be performed in case of HSLI?
It could probably be helpful, if a table of example CRC results for various input values would be included in the datasheet, similarly as it is done in the Autosar document Specification of CRC Routines; this way users could perform a test for plausibility of their crc implementations, before sending actual requests to the TLD7002.
Regards,
Michael
