The ADM1818 range has 2.88 V and 2.55 V (typical) trip point
options that allow the user to monitor 3.3 V and 3 V supplies.
For 5 V monitoring requirements, the ADM1813 range has 4.62 V
and 4.35 V (typical) trip point options.

ADM1810, ADM1812, ADM1815, AND ADM1817
The ADM1812 is a 5 V supply monitor with an active high push-
pull output and trip point options of 4.62 V and 4.35 V typical.
The ADM1810 is similar to the ADM1812, except that the
ADM1810 has an active low push-pull output stage. The ADM1817
is suitable for monitoring 3.3 V, 3 V, and 2.5 V supplies, with an
active high push-pull output and trip point options of 3.06 V,
2.88 V, 2.55 V, 2.31 V, and 2.18 V typical. The ADM1815 is similar

to the ADM1817, except that the ADM1815 has an active low
push-pull output stage.
The ADM1810/ADM1812/ADM1815/ADM1817 can connect
directly to most microprocessor reset inputs without the need for
external components.

ADM1813 AND ADM1818
The ADM1813 and ADM1818 are low cost voltage monitoring
devices featuring an open-drain output and optional push-button
reset function.

ADM1811 AND ADM1816
The ADM1811 is a 5 V supply monitor with an active low open-
drain output and trip point options of 4.62 V and 4.35 V typical.
The ADM1816 also has an active low open-drain output but is
suitable for monitoring lower voltage supplies of 3.3 V, 3 V,

the push-button reset button pulls the RST output low for a period
greater than 1 μs when the reset button releases the RST line to
float high, then the RST line stays low for another 150 ms typical.
