ADM809ZAKS-REEL

Supervisors Overview

The ADM809ZAKS-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor supervision. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output type with one monitored input. The device provides a reset delay time of 240 ms and maintains an accuracy of 1.5%. It functions reliably across a temperature range from -40 C to +125 C, consuming only 60 uA of operating power. The component is housed in an SOT-23-3 package and includes specific threshold voltages such as 2.32 V.

Supervisors Feature Summary

• Provides precise voltage monitoring with high accuracy for system reliability
• Features a compact surface-mount package suitable for space-constrained designs
• Operates efficiently with low power consumption across wide temperature ranges

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix and reel configuration when ordering, as availability may vary. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as documentation indicates varying compliance levels across similar part numbers. Ensure the specific batch matches project requirements for lead times and stock status.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with a 240 ms delay is required. The SOT-23-3 package offers a small footprint compared to SC-70 alternatives. Consider the 1.5% accuracy and 60 uA current draw for battery-sensitive applications. Verify that the 2.32 V threshold aligns with the target rail voltage.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. The series focuses on providing reliable reset signals for digital systems. The ZAKS designation typically indicates specific threshold and packaging variations within the broader product family, distinguishing it from other variants like the RAKS or TAKSZ models.

Supervisors Replacement Considerations

Check for ADM809ZARTZ-REEL7 as a potential substitute with similar electrical characteristics. Verify pin compatibility and threshold voltage alignment before substitution. Other ADM809 variants may require schematic adjustments due to different delay times or packages.
