ADM809LARTZ-REEL7

Supervisors Overview

The ADM809LARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 4.63 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It lacks manual reset, watchdog timer, or battery backup switch capabilities. Operating current is 60 uA, and it supports an extended temperature range from -40 C to +125 C. The component is housed in an SOT-23-3 package.

Supervisors Feature Summary

• Provides voltage supervision with a fixed threshold of 4.63 V
• Features a push-pull output driver for direct logic interfacing
• Operates over an extended industrial temperature range up to +125 C

Supervisors Applications

• Microprocessor system reset generation
• Portable equipment power management
• Battery-powered consumer electronics

Supervisors Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing. Confirm the LARTZ designation corresponds to the 4.63 V threshold variant. Ensure compatibility with SOT-23-3 footprint requirements. Check regional availability restrictions as some distributors may list limited stock status. Validate RoHS compliance documentation for final assembly integration.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for systems operating near 5 V. The low 60 uA quiescent current makes it suitable for battery-operated devices. The absence of manual reset simplifies design if external control is unnecessary. Verify that the 240 ms delay meets system startup timing requirements. Consider the SOT-23-3 package size constraints for PCB layout.
