TPS2421 enable pin

Other Parts Discussed in Thread: TPS2421-1

looking to use the Tps2421-1 in a product.

Vin is 4-14V

Data sheet IMPLIES it can be driven by 3.3-5V  logic, yet block diagram shows this pin pulled up to VIN..which I think was a dumb move.

Do I need to add an external fet to drive this with 3.3V logic?
