ADM811SARTZ-REEL - Voltage Supervisor IC by Analog Devices Inc.

The ADM811SARTZ-REEL is a robust voltage supervisor integrated circuit designed and manufactured by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This particular device is part of the REEL series, indicating that it is provided in tape and reel packaging, which is ideal for automated assembly processes commonly used in large-scale manufacturing.

The ADM811SARTZ-REEL is designed to monitor power supplies in microprocessor systems, providing a precise, low-power method for monitoring the system voltage. When the monitored voltage falls below the factory-programmed threshold, the reset output is asserted, which remains asserted for a minimum duration even after the voltage rises above the reset threshold. This ensures proper system reset and provides a stable environment for the microprocessor to initialize.

This voltage supervisor IC offers several key features that make it a reliable and essential component in critical power management applications. It has a reset timeout period of 140 ms, ensuring adequate time for the system to stabilize after a power disturbance. The device operates over a wide supply range, making it versatile for various applications. Additionally, it boasts low power consumption, which is crucial for battery-operated devices where power efficiency is of the utmost importance.

The ADM811SARTZ-REEL comes in a compact SOT-143 package, which is suitable for space-constrained applications. The small footprint of the device, combined with its high level of integration, reduces the need for additional components, thus simplifying the design and reducing the overall bill of materials.

In summary, the ADM811SARTZ-REEL voltage supervisor from Analog Devices Inc. is a high-quality, reliable component that provides critical monitoring and control for power supply systems. Its combination of features, including factory-programmed threshold levels, low power consumption, and compact packaging, make it an excellent choice for designers looking to enhance the reliability and efficiency of their electronic systems.
