ADM811RARTZ-REEL7

The ADM811RARTZ-REEL7, manufactured by Analog Devices, is a microprocessor supervisory circuit designed for reliable voltage monitoring in various systems. This component is suitable for applications including microprocessor systems, controllers, intelligent instruments, automotive systems, safety systems, and portable instruments.

Key electrical specifications include a typical supply current of 5 μA and a minimum power-on reset time of 140 ms. It provides reset assertion down to 1 V and offers precision voltage monitoring options for 2.5 V, 3 V, 3.3 V, and 5 V supply levels. The circuit is housed in a 4-lead SOT-143 package.

This device includes a debounced manual reset input, allowing for system resets via an electrical switch or another digital device, or triggered by a degradation of the supply voltage. This manual reset function is crucial for reducing potential damage or danger in locked or out-of-control system states.

The ADM811RARTZ-REEL7 is designed to monitor voltage degradation, allowing for a 5% or 10% drop in standard PSU voltages before initiating a reset. This ensures system stability and integrity by preventing operation under unstable voltage conditions.
