The ADM811MART is a robust voltage supervisor designed to monitor power supplies in microprocessor and digital systems, providing a significant layer of protection and reliability. Manufactured by Analog Devices Inc., a leader in semiconductor design and manufacturing, this device ensures that systems operate within their voltage thresholds, protecting against data corruption and hardware damage caused by unexpected power fluctuations.

Key Features

• Reset Output: The ADM811MART features an active low reset output. This crucial function ensures that the connected microprocessor or digital system is reset to a known state during power-up, power-down, or brown-out conditions.
• Voltage Monitoring: It monitors the power supply voltage and maintains a reset output until the voltage reaches a stable operating level, and then maintains the reset for a specified period, ensuring proper system boot-up.
• Manual Reset Input: This device includes a manual reset input that allows for a system reset to be initiated at any time, providing additional control and flexibility for system maintenance and troubleshooting.
• Low Power Consumption: The ADM811MART is designed for low power consumption, making it an ideal choice for portable and battery-operated applications where power efficiency is critical.

Applications

The ADM811MART is suited for a wide range of applications, including:

• Computers and servers
• Embedded systems
• Portable and battery-powered devices
• Industrial and automotive systems

Technical Specifications

With an operating temperature range of -40°C to +85°C, the ADM811MART can function reliably in extreme conditions. It comes in a compact SOT-23 package, making it suitable for space-constrained applications. The supervisor threshold voltage is precisely set at the factory, ensuring accurate monitoring without the need for external components.
