ADM1810–ADM1813/ADM1815–ADM1818
ADM1813 AND ADM1818
The ADM1813 and ADM1818 are low cost voltage monitoring
devices with the inclusion of an optional push-button reset
function.
An optional push-button reset switch can be connected be-
tween 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 options which allow the user to
monitor 3.3 V supplies with 10% and 20% tolerance options.
While the ADM1813 range has options which allow the user
to monitor 5 V supplies with 5%, 10% and a 15% tolerance
options.
ADM1810, ADM1812, ADM1815 AND ADM1817
The ADM1812 is a 5 V low cost voltage monitor with an active
high push-pull output. The ADM1812 supports 5%, 10% and
15% tolerances. The ADM1810 is similar to the ADM1812,
except that the ADM1810 has an active low push-pull output.
The ADM1817 is 3.3 V voltage monitor with an active high
push-pull output. The ADM1817 supports 5%, 10% and 20%
tolerances. The ADM1815 is similar to the ADM1817, except
that the ADM1815 has an active low push-pull output.
The ADM1810/ADM1812/ADM1815/ADM1817 can be con-
nected directly to most microprocessor-reset inputs without the
need for external components.

ADM1811 AND ADM1816
The ADM1811 is a low cost voltage monitor with an open drain
output. The ADM1811 is designed to monitor 5 V supplies.
The ADM1811 range comes in three different variants which
allow the monitoring of a 5 V supply with a tolerance of 5%,
10% and 15%. The ADM1816 is a 3.3 V version of the ADM1811
and supports 5%, 10% and 20% tolerance options.
