GENERAL DESCRIPTION
The ADM181x range of voltage monitoring circuits is used in
any application where an electronic system needs to be reset
when a voltage increases above or below a predetermined value.
Because of the reset delay time incorporated into the ADM181x
series, these devices provide a safe startup for electronic systems.
Before a system initializes, the power supply must stabilize.
Using the ADM181x series ensures that there are typically 150 ms
for the power supply to stabilize before the system resets and
safe system initialization begins.
The ADM181x series of microprocessor reset circuits are
available in low cost, space-saving SOT-23 and SC70 packages.

Figure 11. ADM1813/ADM1818 Typical Application
An optional push-button reset switch can be connected between
RST and ground. Pressing this switch pulls the reset output low. If
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.

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.
