ADM1811-5ARTZ-RL7

ADM1811 is a microprocessor reset circuit 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 this series, these devices provide a safe start-up for electronic systems. Before a system initializes, the power supply must stabilize. Using this series ensures that there are typically 150ms for the power supply to stabilize before the system resets and safe system initialization begins. Typical applications are microprocessor systems, computers, controllers, intelligent instruments, automotive systems.
