USB2240 chip heating
I have working on USB2240 - SD to USB bridge, I have incorporated all the required components which is required to run the chip (seen from the USB2240 Evaluation board) on to my PCB, all the parts on the PCB is assembled by PCB manufacturer (No hand soldering is done) I can connect USB2240 controller to my computer and i can see SD card in my computer as mass storage device , i can Read/Write data from the SD card for few seconds, after some time the controller heats up! and shut down it self.
I am supplying 3.3V from a regulator continuously at this time it's not at all heating up, It's heating only when i connect controller to my computer..
I am attaching my schematics along with this thread, please find my mistake.
Note : R46 is not populated on my PCB.
Note 2 : I have also tried connecting CRD_PWR pin to SD card but no use.
