Hello,
I have designed a USB Hub using the TI TUSB2046B Chip. Attached is the picture of the schematic.
For some reason I am not able to get the desired outcome.
We are not using the EEPROM, so the EECLK is left floating
Pin 32 is NC
Pins 27, 7, 28, 31 are tied to GND
Pins 3 & 25 have VCC.
When I power up the circuit, it doesn't recognize the chip, apart from a message saying Power surge on the USB Hub.
Do we need to add something to this cirucit? Between TPS2044 & TUSB2046 to make it work?
Please let me know so we can fix this.
Thanks
Jas
