Part Number: TPS2546

Will the TPS2546 still auto-detect the load if the enable pin is pulled low?

No, it won't.

Since the TPS2546 has high quiescent current, is there another IC or way for the TPS2546 to detect if a load is being attached?

What is the suggested low power implementation to detect if a load is attached before one enables switches to provide output power to an external USB device?
