TPS54302: EN pin parameters

Part Number: TPS54302

Can I place a 0.1uF cap from EN to GND?  If not can I couple it through a resistor?  What is the max input current of that pin?

    The data sheet indicates that there is a 0.5uA to 1.5uA current source at the EN input.

    This is used to provide hysteresis if the EN pin is used as an external UVLO.

    Not sure what your reason is for the 0.1uF capacitor but I do not see anything wrong.

    Can you send a schematic and more details.
