ADM811TARTZ-REEL7

Supervisors Overview

The ADM811TARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 5.5 V and features an active low output type. The device monitors a single input with a threshold voltage of 3.08 V. It includes manual reset functionality but lacks a watchdog timer or battery backup switch. The reset delay time is specified at 560 ms. Designed for surface mount installation, it is housed in a SOT-143-4 package.

Supervisors Feature Summary

• Provides precise voltage monitoring for standard power rails
• Includes debounced manual reset input to prevent system lockup
• Operates with low power consumption across the full temperature range

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supplies
• System reset generation in industrial applications
• Preventing system damage from undervoltage conditions

Supervisors Procurement Notes

Verify component authenticity through official Analog Devices channels due to limited availability status. Confirm package integrity and pin alignment against the SOT-143-4 specification before integration. Ensure environmental compliance documentation matches project requirements. Cross-reference datasheet revisions to confirm parameter consistency. Validate supplier authorization to mitigate counterfeit risks.

Supervisors Selection Notes

Select this component when a reliable supervisor for standard voltage rails is required. The 3.08 V threshold suits specific 3 V systems. Manual reset capability allows user intervention during fault states. Consider the 560 ms delay for system stability. Verify compatibility with target PCB footprint and operating temperature range constraints.

Supervisors Part Context

This part belongs to the ADM811/ADM812 family of voltage supervisors. These devices are designed as upgrades for older MAX811/MAX812 series components. They offer improved performance across the entire temperature range while maintaining similar functional characteristics. The family supports multiple fixed voltage thresholds for common digital logic levels.

Supervisors Replacement Considerations

APX811-26UG-7 is listed as a parameter equivalent alternative.
