My academic project involves implementing a wireless charger using the WLC1115 chip, which will perform authentication to ensure that the transmitter (Tx) can only be used with a specific receiver (Rx), and vice versa. To achieve this, I plan to use the OPTIGA Trust M chip. I have some specific questions related to this process and would greatly appreciate it if you could help me address them.
-
Which of the two methods for programming the WLC1115 chip do you recommend that is more easily accessible in the market and that can fully program the chip or modify its firmware?
-
Can I use the configuration tool provided by you for the basic configuration of the chip with the miprog4?
-
Can I use the chip without the Optiga trust charge but with the Optiga trust M?
-
Can I achieve a power greater than 10W without the Optiga trust charge?
-
What could I do if I want to transmit data between Tx and Rx?
- How can I program the Optiga Trust M?
Good day. I am developing an academic application which involves the development and implementation of a wireless charger with authentication. However, the authentication part mostly involves customizing the wireless charger for a single receiver (device). Initially, I relied on the WLC1115_68LQXQ chip, but the issue with this chip is that it is Qi 1.3 compliant, including authentication via Optiga, and I'm not sure if Optiga allows the authentication I require. I would like to know what ideas or recommendations you have for implementing the authentication of the wireless charger I need, or what other charging chip you would recommend.
Thank you.
Show LessMy name is Dexaca, and I am reaching out to inquire about the WLC1150 chip. I am looking to integrate this chip into a wireless charger for a project, and I require additional information regarding the corresponding receiver chip.
Furthermore, I am in need of the transmitter and receiver chip for authentication purposes during the charging process. If you could provide detailed specifications, compatibility, and pricing information, it would greatly assist in my decision-making process.
Additionally, I am interested in exploring other wireless charging chip options that adhere to the Qi 1.3 protocol for both transmission and reception of wireless charging. If you have any other product recommendations or references that meet these criteria, I would appreciate the information.
Thank you for your attention to this matter. I anticipate your prompt response and would be grateful for any assistance you can provide.
Show LessHi Infineon,
I am working on a 2.5KW battery charger and I have gone through the Application note of the Evaluation Board (2KW EVAL_2kW_48V_CHAR_P7) a Lead-acid/Li-ion battery charger of Infineon.
Here are my queries.
There is a resistor (R200) across the capacitor (C90) in the schematic but in the evaluation board that resistor is not present. But when I checked the current version of the schematic the capacitor C90 is not present. Can you explain this variation in schematics?
Show LessMay I ask if the output power of the EVAL_3K3W_BIDI_PSFB device in boost mode is limited, and if so, how can I lift the limit so that it can output full load power.
Please don't hesitate to teach me!

Show LessDear Infineon Team:
our customer have new project " AGV Robot" want to use Infineon 24G and 60G radar sensor.
customer bought below demo board each 5 set.
DEMOSENSE2GOLPULSETOBO1 (SP005400656)-- XENSIV™ 24 GHz radar
DEMO BGT60LTR11AIP (SP005422969) -- 60GHz XENSIV™ radar sensor BGT60LTR11AIP (configured in SPI mode)
Customer want to know below information:
1. If infineon has total solutions for AGV robot, eg. logistics robot, obstacle avoidance robot, intelligent wheelchair
best regards
Sam Zhang
2. any software or tools for above demo board
3. any suggestion on AGV robot if customer use Infineon 24G/60G radar sensor, eg: Angle, distance, range
Show LessDear experts
I already use Infineon solution to design PD3.1 application.
and I have some questions about design document, please give me some suggestions, thanks.
1. how do you know the resonant period is Tr/2? could you please explain it more detail?
2. When should the secondary-side MOSFET be turned off, and how can this objective be achieved using open-loop control in SIMPLIS, I would like to use SIMPLIS to know the operation of AHB CRM mode, but it seems you don't have any simulation file in the website. if I use diode in the secondary is it ok?
3.Why is the waveform at the red-circled region different in these two images?
4. How to determine the dead time and the value of capacitor Cr?
5. How to optimize the CM noise in this topology? I want to modify it from the transformer side.

Hi
Myself : Nihal khan
In infineon code for PFC_Stage 3.3KW on board charger there is Ntc lookup table form where we are selecting the temperature based on the index value. i have doubt in calculation of ntc lookup table
pls share the the specification of NTC which is used in PFC_Stage 3.3KW on board charger and also the method or equations to calculate the ntc lookup table
