Product Summary

The ADM1818-5ARTZ-REEL7 is a Microprocessor Reset Circuit. The ADM1818-5ARTZ-REEL7 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 ADM1818-5ARTZ-REEL7, the device provides a safe startup for electronic systems. Before a system initializes, the power supply must stabilize. Using the ADM1818-5ARTZ-REEL7 ensures that there are typically 150 ms for the power supply to stabilize before the system resets and safe system initialization begins. The ADM1818-5ARTZ-REEL7 is available in low cost, space-saving SOT-23 and SC70 packages. The applications of the ADM1818-5ARTZ-REEL7 include Microprocessor systems, Computers, Controllers, Intelligent instruments and Automotive systems.
