ADM811TART-REEL7

Supervisors Overview

The ADM811TART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 3.08 V. The device provides an active low output signal with a reset delay time of 560 ms. It includes manual reset functionality but lacks watchdog timer or battery backup switch capabilities. Packaged in SOT-143-4, it supports surface mount installation and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with manual reset capability
• Features active low output for system reset generation
• Operates with low quiescent current consumption

Supervisors Applications

• Monitoring 3.08 V power rails in embedded systems
• Generating reset signals for microprocessors under low voltage conditions
• Protecting circuits against undervoltage events in portable devices

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity and pin alignment for SOT-143-4 mounting. Ensure environmental compliance documentation matches project requirements. Cross-reference datasheet revisions to validate electrical parameters before integration into final designs.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-channel supervision. Consider the active low output polarity and 560 ms delay duration for timing compatibility. Evaluate the absence of watchdog features if system reliability requires automated recovery mechanisms beyond manual intervention.

Supervisors Part Context

Part of the ADM811 series, which offers various threshold options for standard voltage levels. This specific variant targets applications requiring a 3.08 V trip point. The series is known for replacing older generations like MAX811 with improved performance characteristics across industrial temperature ranges.
