Analog Devices Inc. ADM1817-5AKS-REEL7

Description
The ADM181x series of voltage monitoring circuits are used in applications where an electronic system needs to be reset when a voltage increases above or below a predetermined value. These devices provide a safe startup for electronic systems by incorporating a reset delay time. Before a system initializes, the power supply must stabilize. Using the ADM181x series ensures that there is typically 150 ms for the power supply to stabilize before the system resets and safe system initialization begins.

Features
Reliable low-cost voltage monitor with reset output
Suitable for monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supply voltages
Reset threshold levels: 4.62 V, 4.35 V, 3.06 V, 2.88 V, 2.55 V, 2.31 V, and 2.18 V typical
Active high and low push-pull output choices: ADM1810, ADM1812, ADM1815, and ADM1817
Open-drain with internal pull-up resistor output choices: ADM1811, ADM1813, ADM1816, and ADM1818
