where should i connect the exposed pad of WSON 5 x 6 mm package?
Hello everyone,
I would like to set up various chargers in the DC range. Infineon offers chargers in the range 50-350 kW, but unfortunately I don't really know yet which exact components I need for the respective charging station. Is there possibly already an exemplary composition of components for certain charging powers? In other words, a list with the required components / number for a charging station with 50 kW, one for 150 kW and one for 350 kW.
Can anyone in the community help me here?
Show LessWhen viewing a Discussion Page, we can sort the viewing order of messages by selecting options from the drop down menu "Sort by:". This feature has stopped working properly.
I have this option set to "Most recent activity". However, it's applying "Most recent thread" even though "Most recent activity" is being displayed.
My work-around is to select "Most recent thread" and then re-select "Most recent activity" and now it displays the most recent activity.
Also, "Show More" is no longer working to expand a thread. Clicking on it does nothing.
PC Win10, MS Edge and Chrome have same results. Hopefully this can be fixed. It used to work.
Show LessIt is not possible to navigate through the left navigation menu. When "Microcontrollers" is expanded, there is no chance to reach the submenu entry for AURIX. If I move my mouse along the right red arrow, the menu collapses when the box "Microcontrollers" is left and the white background reached. If I instead take the left way downwards, then the list of "Microcontrollers" is also closed but the subsequent entries for "USB", "Wireless Connectivity" and so on are opened instead.
So there is no possibility to reach any submenu item. It is obvious that the submenu is shiftet down one line by error. If the first entry "PSoC 6" would be right next to "Microcontrollers", then one could move the the mouse in right direction from Microcontrollers and then head down to AURIX.
Hello,
I didn't find how to change my email address in profile.
My company changes our e-mail address. I'm still able to receive emails with the former address for a couple of months, but this will be no longer soon.

https://community.infineon.com/t5/MEMS-microphones/bd-p/memsmicrophones
They all give an error "An invalid set of parameters has been specified in the url."
Show LessHi,
As I found a mistake in the schematic of my sample project,
I posted the correction and comments this morning.
https://community.infineon.com/t5/Code-Examples/MCU-Tester-a-Swiss-Army-Knife-for-PSoC-TSoC-version/m-p/175820
Then I could not find the page and when finally I found the page, it's marked as [ SPAM ]
I wonder what should I do with this.

Hey there,
my Merus Amp HAT sometimes stops working. To Boot the Pi doesnt help everytime. Same error one different PiOS SD-Cards. For now im not able to fix it.
Behavior:
Starting a MP3 seem to work. Time is running, but there ist no sound. I used different player, which all worked a few day ago.
PiOS 32bit 04.04.2022

What can i do?

Show LessWe want to make a rechargeable street light. Its have two sections. Battery charger and DC to DC converter. When electric supply is present the LiFePO4 Battery will be charged. If electric supply is not available in evening or night time, the street light will be ON by battery backup and Its will be OFF in day time. We will be use a 4 volt 0.10 Amp solar chip to sense dusk and down. Street lights will be operate as per dusk down. Its have the following features-
1) Input Operating working voltage------85 V to 300 V AC ( 300v to 450 volt stand by mode).
2) Output Voltage----------------------Its have two types outputs-------------
(A) Driver Output Voltage-------- Suitable for the charging of 12.8V, 20 AH Lithium phosphate LiFePO4 Battery. Battery will be charged within 5 hours. Driver wattage is not less than 80 watt.
(B) Boost converter Output---------- 40 watt ( 36 Volt, 1.12 Amp) suitable to operate 40 watt 36 volt LED strings.
3) Cut Off and protections---------------- Low and high cut off requirements in both sections (Charger and DC to DC converter). All protections also needs whose requirements in LED Street Lights. Charger and DC to DC converter will be operate in CV CC mode. Max current limit of the charger will 5 amp and converter max current limit will 1.5 amp.
4) Dc to DC converter--------Suitable to operate by 12.8 volt LiFePO4 battery. It's "ON" only during the night period. To sense day or night we will use a 4 volt 0.1 Amp Solar Chip when the solar chip voltage is greater than 1 volt then the light is "OFF" and when the solar chip voltage is less than 1 volt the Light will be "ON".Tempreture sensor can use to protect the driver from over heat.
Please design the very compact and strong driver suitable for avobe all feature. If possible design by using microcontroller.
Thanking you
