TPS2003C: Need help picking a current limiter for a USB port power

Part Number: TPS2003C

Hi,

I need help picking the best part for my application. I am using the T.I. reference design (tidrbt8.pdf) for the TUSB8041 USB hub that uses the TPS2003C for power limiting on ports 1&2. In my application I want to limit the current available from the USB ports to 500mA per port. What part do I need for this? I did come across another part, TPS256x Dual Channel Precision Adjustable Current-limited Power Switches. This design is for an automotive application so it would be desirable to find a part rated for automotive use.

Thanks,

Jim T.
