t. This active-low pin serves as the 3V push/pull reset
output. A reset is asserted when any one of the supplies are below its
respective trip threshold and the reset is held for 200ms after all power supplies
have stabilized.

. 1.8V sense input and power detect pin (AS1920-18, AS1922-18). This
pin provides power to the output reset stage of the device in order to assert a
valid reset when the voltage on the primary input is down.
