GENERAL DESCRIPTION
The ADM181x range of voltage monitoring circuits can be 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 can provide a safe startup for electronic
systems. Before a system initializes, the power supply must stabi-
lize. Using the ADM181x series ensures that there are typically
150 ms for the power supply to stabilize before the system is
reset and safe system initialization begins.
The ADM181x series of microprocessor reset circuits are avail-
able in low cost, space-saving SOT-23 packages.
