ADM809RAKSZ-REEL7

Supervisors Overview

The ADM809RAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor supervision applications. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 2.63 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It consumes a working power supply current of 60 uA and supports an overvoltage threshold of 2.66 V. The component is housed in an SC-70-3 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable microprocessor supervision through dedicated voltage monitoring capabilities
• Features a compact SC-70-3 surface-mount package for space-constrained designs
• Delivers a push-pull output signal for direct interface with digital logic

Supervisors Applications

• Microprocessor reset generation
• Voltage supervision in portable electronics
• Battery-powered system monitoring

Supervisors Procurement Notes

Verify the specific suffix 'RA' indicates the correct 2.63 V threshold voltage variant required for the design. Confirm that the REEL7 packaging format aligns with automated assembly equipment specifications. Ensure compatibility with the target operating temperature range of -40°C to +125°C. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.63 V supervision threshold is necessary for low-voltage systems. The 60 uA quiescent current makes it suitable for battery-operated devices where power efficiency is critical. The SC-70-3 package offers a small footprint compared to larger alternatives. Consider the 240 ms reset delay duration to ensure adequate stabilization time for the monitored circuit during power-up events.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. The series typically includes various threshold voltages and package options to suit different application requirements. The RAKSZ designation specifies the particular voltage threshold and the SC-70-3 surface-mount package configuration used in this specific reel-packaged unit.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers within the ADM809 family that match the required threshold voltage and package type.
