ADM810LART-REEL7

Supervisors Overview

The ADM810LART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold of 4.63 V with an overvoltage threshold of 4.7 V. The device provides a push-pull output and includes a reset delay time of 240 ms. It exhibits high accuracy of 1.5% and consumes a typical operating supply current of 60 uA. Packaged in a SOT-23-3 surface-mount format, it supports industrial temperature ranges from -40°C to +125°C.

Supervisors Feature Summary

• Monitors a single voltage input channel with a fixed threshold for reliable system supervision.
• Delivers a push-pull active-high reset signal to ensure robust logic interface compatibility.
• Incorporates a defined reset delay timer to prevent false triggering during power-up transients.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity upon receipt as the part is supplied in reel packaging. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Cross-reference the full part number including suffixes to match exact electrical characteristics. Validate supplier documentation against official Analog Devices specifications before integration into production.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-rail supervision. The low quiescent current of 60 uA makes it suitable for battery-operated applications. The wide operating temperature range supports industrial environments. Consider the SOT-23-3 package size for space-constrained designs. Verify that the 240 ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This part belongs to the ADM810 series of voltage supervisors from Analog Devices. It shares architectural similarities with other members like the ADM810RART but differs in threshold voltage settings. The series is designed for general-purpose power management tasks requiring simple, reliable reset generation without complex configuration interfaces.

Supervisors Replacement Considerations

Direct substitutes include ADM810RART (2.63V threshold) or ADM810MAKSZ (different package). Verify threshold voltage compatibility before substitution. Check pinout alignment and thermal performance differences. Ensure reset delay times meet system requirements for alternative packages.
