I am not clear about the differences between different types of devices. For example: 2EDL05N06PF and 2ED2304S06F,
it is very confusing to choose, because they look very similar, so I can only ask infineon for support, I will publish my motor parameters as follows:
It is a PMSM motor, 48V nominal voltage, I will use FOC to drive it
As an added bonus, my PCB is very size sensitive, so only choose DSO-8 type package
it is very confusing to choose, because they look very similar, so I can only ask infineon for support, I will publish my motor parameters as follows:

Continuous Current: Adc --> 12.00 | Arms --> 10.00
Peak Current: Adc --> 40.00 | Arms --> 30.00
Rated Cont Power: Watts --> 350
Speed at Rated Power: RPM --> 2400
Design Voltage(Rated voltage): Vbus --> 48.0 (Vdc) | Vac --> 34(Vrms)
Back EMF at Temp: Vpk / kRPM -->18.5 | Vrms/kRPM --> 13.0
Back EMF: Vpk / kRPM --> 19.0 | Vrms/kRPM -> 14.0
Motor Constant at 25°C: N-m/√watt --> 0.28 | oz-in/√watt --> 39.5
Inductance: Lm --> 0.55
As an added bonus, my PCB is very size sensitive, so only choose DSO-8 type package

Hello Jason,
Thank you for posting on Infineon Forums.
The gate driver selection can be defined by some main parameters:
-Type of topology needed (low side driver, half bridge driver, inverter driver etc.)
-How fast do you want to turn on/off the switch (driver output current)
-Blocking voltage of application (in your case >48V)
-Type of switch (Si, SiC, GaN, logic level or not)
-Isolation type
After that is defined, it is a matter of the features you would like to have in the driver.
For example, you mentioned 2EDL05N06PF and 2ED2304S06F.
These drivers belong to different families, and the reason for the naming difference is that they follow a different naming convention.
But as you noted, they have almost identical characteristics.
https://www.infineon.com/dgdl/Infineon-Gate_Driver_Application_Selection_Matrix-ProductSelectionGuid...
Slides 8 to 11 of the document above describe the logic behind each naming convention.
I understand that the naming is confusing and we are working on having a common naming scheme.
Infineon offers a gate driver finder:
https://www.infineon.com/cms/en/design-support/finder-selection-tools/product-finder/gate-driver/?re...
Here you can input your main requirements for the driver, and an automated search will give you the suitable parts.
If your PCB is very size sensitive, you could use a 6ED part (six-channel driver for inverter applications).
Again, I encourage you to use the Gate Driver Finder tool mentioned above.
Best regards,
Pablo
