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.
