ADM809SARTZ-REEL7

Supervisors Overview

The ADM809SARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 2.93 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switching capabilities. The component draws a working supply current of 60 uA and supports an overvoltage threshold of 2.96 V. It is available in SOT-23-3 packaging and operates 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 when supply voltage deviates from specified thresholds
• Operates reliably across extended industrial temperature ranges for robust performance

Supervisors Applications

• Microprocessor supervisor circuits requiring precise voltage monitoring
• Power management systems utilizing supervisory ICs for fault detection
• Electronic devices needing automated reset generation upon power failure

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package type and electrical specifications. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure compatibility with existing PCB footprints and thermal requirements before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 2.93 V is required for system supervision. Consider the SOT-23-3 package size for space-constrained applications. Evaluate the 240 ms reset delay against system startup timing requirements. Verify that the absence of manual reset and watchdog features aligns with the specific design architecture.

Supervisors Part Context

This component belongs to the ADM809 series of supervisory circuits from Analog Devices Inc. The series focuses on providing reliable voltage monitoring solutions for various digital and analog systems. The ARTZ suffix typically denotes specific packaging and environmental compliance attributes defined by the manufacturer for surface-mount assembly processes.

Supervisors Replacement Considerations

Consult official Analog Devices cross-reference tools for verified substitutes. Ensure any replacement matches the 2.93 V threshold, SOT-23-3 package, and 5.5 V maximum voltage rating. Verify functional equivalence regarding reset delay and output configuration.
