ADM809SARTZ-REEL

Supervisors Overview

The ADM809SARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.32 V with an overvoltage threshold of 2.35 V. The device provides a push-pull output type and includes a reset delay time of 240 ms. It exhibits an accuracy of 1.5% and consumes a working supply current of 60 uA. The component supports SMD/SMT installation in an SOT-23-3 package and functions reliably across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides continuous monitoring of single input voltage levels to ensure system stability
• Generates reset signals via a push-pull output interface upon detecting out-of-range conditions
• Operates with low power consumption suitable for battery-powered or energy-efficient applications

Supervisors Applications

• Microprocessor supervisor circuits requiring precise voltage tracking
• Portable electronic devices utilizing low-power monitoring solutions
• Industrial control systems operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix configuration against official documentation to confirm pinout and electrical characteristics, as variations may exist within the product family. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration. Ensure the selected package matches the intended PCB footprint requirements. Cross-reference the part number with authorized distributors to validate authenticity and traceability.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with a fixed threshold near 2.32 V is required. Consider the 240 ms reset delay duration relative to system startup timing constraints. Evaluate the 60 uA supply current against overall power budget limitations. Verify that the SOT-23-3 package dimensions fit the available board space. Assess the 1.5% accuracy specification against the required monitoring precision for the target application.

Supervisors Part Context

This component belongs to the ADM809 series of supervisory circuits from Analog Devices Inc. The series focuses on providing reliable power management monitoring for embedded systems. The REEL suffix indicates the standard tape and reel packaging format used for automated assembly processes. This family typically targets applications needing compact footprints and robust performance under varying thermal conditions.

Supervisors Replacement Considerations

Direct substitutes include other ADM809 variants with compatible thresholds and packages. Verify pin compatibility and electrical specifications before substitution. Consult official cross-reference guides for approved alternatives.
