Hi Folks,
I am working on ICE2HS01G , half bridge LLC Controller, I have connected the circuit as p0er the reference design. However, I am unable to get Vref of 5V at pin 9. I am giving a Vcc of 13V, internally vreg of 5v and Vdd should be generated as per the data sheet, but I am facing issue there. Because of it there is no 4V on ENA pin and no output on Lg and HG pins.
Please guide if any one had faced similar issue.
Thank you

Hi all ,
I am working on Li-ion battery charger and I have gone through the one of manual of 2KW Lead-acid/Li-ion battery charger.
I attached the link for the same. Following are some of my queries regarding the same.
1. I want all the magnetic data such as PFC inductor, LLC inductor, main transformer and biased supply transformer how can I get this.
I tries to add the pdf file but there is some tricky so I could not.'
2. When I was looking into the schematic they have used NT1,NT2.....and so on. I tried to find out about these notations I could not find and explanation for the same.
Please help me to sort this out. What are these notations means ???
Waiting for your valuable reply..
Thanks..

Hello,
We want to develop a USB-C charger and we need to check the battery charge percentage of the device connected to the USB-C charger. The connected to de USB-C device can be a Smartphone, Tablet or PC.
In our charger we are going to integrate a processor and we need to read the battery percentage of the device that is being charged
Is it possible to read the battery percentage of the device connected by USB-C? Any Infineon reference can do this job?

Show LessI would like to know the possibilities of LLC topology in charger applications.
In the whitepaper at the following URL, there is a description of the main LLC position, but it is not mentioned in the topology comparison in Table 1.
Can someone add LLC to this table?

Hi. Infineon
In my application; use 3172P to design in type-C adapter. now, the QC2.0 and QC3.0 OCP test data as below,230V AC input ,the QC2.0 and QC3.0 12V2.5A and 20V 1.5A OCP test result is 3.44A and 2.32A. I try to modify the battery.charging.h QC_AMP_20V(300 -->210 and 110) and QC_AMP_12V(300-->110 and 90) , but the test ressult without any change. would you like to let me know where to change to let the OCP meet customer requirement. and add schematic in here.
thanks
