hello
I want to change the state to NORMAL-state, but I don't understand what the second condition means.
What do I have to do to satisfy the second condition?

hello,
I have a problem initializing TLF35584, please help me out
1. The write operation on the WDCFG0(0x06) register and SYSPCFG1(0x05) register has no effect. Please help me find the reason
1.1 Program diagram
1.2 PROTSTAT register oscillograph display
2. What I understand from the picture below is that if I want to enter normal mode,
I need to write: 0xAA05 in the DEVCTRL register
I need to write: 0xACFB in the DEVCTRLN register
Am I understanding this correctly?

Hi Infineon team,
I want to know the TLS820F0EL Load transient response curve.
Because, Control behavior of voltage regulator is unclear: please provide evidence for stability via reaction on load steps and via delineation of gain and phase response over frequency.
Thanks!

I am using PowIRCenter Build 7832 to create programming files for an IRPS5401 PMIC. I am using the "Design Wizard" and it has been working well. But I am having trouble with the PMIC on my new board tripping the OC fault limit on startup sometimes. So I want to change the OC fault limit behavior from immediate shutdown to "Hiccup 6 times, then shutdown". I already have the current limit as high as I want it, and have taken into consideration startup current due to capacitance on the line.
The Design Wizard has no setting at all for this OC behavior. So I looked at other abilities of the program, and under the tab "Design Tools" I see "Faults and Protection: Behavior or OCP, OVP, UVP". But when I open this screen, there is no setting for OCP ! I have attached as screenshot of this screen. So I have a couple of questions,
1. Is the PowIRCenter program capable of setting this OC fault behavior? If so, please tell me how to do it.
2. Otherwise, is there some other way I can set this OC fault behavior in the programming file?
Thanks for the help,
Jim Brady

你好,
I encountered the following problem when configuring TLF35584
I couldn't write to the PROTCFG(0x03) register because it would cause my MCU to crash.
However, reading the PROTCFG(0x03) register will not cause my MCU to crash.
Writing to other registers will not cause the MCU to crash.
May I ask what causes this situation

I am experimenting with the IR38063 Demo board before programming the part on my board and I have set it up the way I want and went to try and program the MTP region. I selected the config file, did the "Check MTP Left" and I get the following screen:
When I try to "Program and Verify" it give the error message:
There is no check box to the left of MFR as per AN0035 in the programmer section for MFR... It seems like I have 2 MTP area programs left. I updated the software but no difference. What am I doing wrong?
Also what is the User area? It is not described anywhere in the data sheet. The only reference I see is some commands and this programmer.
Thanks,
Dan
Hi,
I am using TLF35584 with STM32-nucleo-F103RB. Upto now I can read and write the registers and clear flag registers. Now I am trying to SPI write to Protected registers. I have followed following sequence but when I am reading the register PROTSTAT, I send 0x5000 and received 0x8002. Window watchdog and error pin doesnt disable yet(DEVSTAT). I have attached the screenshots for your reference.
Unlock:
0x8756
0x87DE
0x86AD
0x8625
Disable watchdog and error pin:
0x8D27
0x8A01
Lock:
0x87BE
0x8668
0x877D
0x8795
Can anyone guide me on this? I need to change the state init to normal after disabling watchdog and error pin.
Thank you.
Show LessHello,
Why does PowIRCenter reporting 0A and not reporting others? Please see attached file.
Hi members.
I have a question about TLF35584 ABIST in a low-voltage environment.
I am currently developing a controller that part of the EV.
The problem is that the TLF35584 fails the ABIST when starting with the 12V battery at a low voltage in the EV vehicle state. [About 7 to 9V]
Currently, I have applied the Boost circuit to TLF35584, so we think there should be no problem.
The strange thing is that the controller alone is connected to the power supply and the issue does not occur during the test.
I wonder if there are any cases where TLF35584 ABIST may not typically perform regarding low voltage.
