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

Figure 3. ADM1813/ADM1818 Typical Application
An optional push-button reset switch can be connected between
RST and ground. Pressing this switch will pull the reset output
low. If the push-button reset button pulls the
RST output low for
a period greater than 1
s, then, when the reset button releases
the
RST line to float high, the RST line will stay low for a further
150 ms typical.

The ADM1818 range has 2.88 V and 2.55 V (typ) 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 (typ) 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 (typ).
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 (typ). 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 be
connected directly to most microprocessor reset inputs without
the need for external components.

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 (typ).
The ADM1816 also has an active low open-drain output but is
suitable for monitoring lower voltage supplies of 3.3 V, 3 V,
and 2.5 V.
