In Asymmetrical Half-Bridge, Hybrid Flyback, how can we optimal current dip design of high frequency by XDPS2221?
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 Less
Looking for a reference design for an On Board Charger:
220-250V AC input
Need automotive grade parts
Need functional safety
Thank youShow Less
请问对于多电压协议充电电路的方案中，sencondary OR Integrated controlle 这部分有没有推荐的芯片，有没有一个完整的方案介绍
I 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?
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.
Applications for CCG3PA in the datasheet only show connections to Type-C Receptacles.
Final systems, where this application are used, will convert the Type-C Receptacle to a Type-C Plug via a USB-C cable. The cable adds a pulldown resistor, Ra, of about 1k ohm and possibly a, EMCA device. If connecting a CCG3PA directly to a Type-C Plug, one CC line can be tied via 1k ohm to ground to provide symmetry. Are any other changes required from the basic design in Figure 8 of the CCG3PA datasheet?
Is the EMCA functionality needed if the physical cable isn't present?
What else is missing? Will CCG3PA software support the "Plug" configuration shown below?
