    Henry,

    The DCDC and LDO are on while the push button is being held LOW, (pressed). Disabling both DCDC and LDO will ultimately cause a RESET. This is because you will have to push the button or apply the AC input to power back on. But, if RESET to you means both DCDC and LDO are on then it already does that.

    If you need a logic signal that goes out to your system then there is the INT and THRESHOLD / RESET pins for use. The INT can be triggered by the push button.

    If you time a little more about what you need I provide more help in implementing it.
