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 stabilize. 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 available in low cost, space-saving SOT-23 packages.
