Could you please teach the failure rate of the VCP function (17pin) of TLE9461ES?
The gate signal of the battery's reverse connection protection FET is driven by this charge pump. If the VCP function is lost, the system may malfunction. Therefore, I would like to know the failure rate of individual parts.

Hi all,
I think that the data format of vout_transition_rate and ton_rise is Linear.
The values of vout_transition_rate and ton_rise are as follows.
In decimal format, vout_transition_rate is 1(8×2-3)[V/ms].
In decimal format, ton_rise is 1(2×2-1)[ms].
Are these correct?
Also, please teach me what u7.3 and s-1.7 stand for.
Best regards,
MS
I faced a rudimentary problem with ICE5QSAG. The start-up of the IC is not working. Powering up the IC with external 15V DC source starts up IC. It continues to work after removal of external DC power.
The application details :
1. Application : Lead Acid (7AH SMF) battery charger
2. Flyback Converter
3. CVCC Controller based on SEA05 IC of ST
4. Ourput : 13.5V, 1A (CVCC)

TLE9012 UM said that in the ring mode the EMM signal will follow the path that shows the RX interface back to the microcontroller. If the contiguous device shows a TX interface, the message will not be forwarded.
But I had a question, The EMM signals how to communicate if the chain is not in ring mode and TLE9012 is in normal operation. The contiguous device shows a TX interface, the message will not be forwarded? or the contiguous devies will change the Tx, Rx interface?
Thanks

Goodnoon
Please help me to understand why the waveform in not continuous:
Yellow: Primary Current, Blue: Output Voltage, Red: HS Vgs, Green: LS Vgs

Show LessMy customer designed PMICs, IR35215 and IRPS5401 for new Xilinx FPGA Versal according to reference guide and schematics.
But I could not find any configuration files on the web page.(
I want to know whether IFX provide a PMIC configuration file or not, and where I can find them.
Show LessHello everyone
do I need additional boards if I want to use the board with my own battery management system? So, for example, the transceiver board?
Is there anything else special that I need to consider?
Thanks in advance
Show LessThank you for this information. I was very confused as to why an "n.c." pin is pulled out at all, but it seems to be going to ground.
I am having issues with the TLE9015. When I provide power on VS (12-28 V) I am expecting Vreg to go to 3.45 V, VDDC to go to 2.5 V, and nSleep to be pulled to 3.3 V. Instead, all three pins are at 0 V. When I force nSleep high by providing 3.3 V, Vreg goes to 1.24 V, and VDDC remains low. I have VIO directly connected to Vregout.
Can you please state the expected chip behavior when supplied power on the VS pins?

Dear All
I am facing problem with LLC Controller. It is not producing proper switching. In the start, there are switching but it stops after some times and there is no 50% Duty cycle in the starting waveform.
Please help me get out from this issue.
Yellow: Input Current, Blue: High SIde FET, Red: Output DC Voltage, Green: Low Side FET.

Hi I am wondering about the Functional Range of the Supply Voltage of the TLE9278BQX V33.
This section of the datasheet claims that the device will be functional from 28V to 40V but some electrical characteristics might not be ensured.
I am working with a system that will be steady state 8-32V and has to survived at 36V for 60 minutes.
I am wondering what I should expect if the system runs from 28V to 32V. The datasheet makes it seem like the device will still be functional, but this seems to go against the absolute max ratings.
Thanks,
Sam
