ADM803RAKSZ-REEL

Supervisors Overview

The ADM803RAKSZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed 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 typical operating current of 60 uA and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SC-70-3 surface-mount format, it supports single-input monitoring without manual reset or watchdog capabilities.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed threshold for reliable system monitoring
• Features a push-pull output stage for direct interface with digital logic
• Operates efficiently with low quiescent current consumption
• Designed for robust performance across wide industrial temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered device voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm package integrity and pin configuration match the SC-70-3 specification before integration. Ensure environmental compliance documentation aligns with project requirements. Cross-reference datasheet revisions to confirm parameter consistency. Validate thermal performance under actual load conditions prior to final deployment.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for low-voltage monitoring applications. Consider the push-pull output capability if active drive strength is necessary for downstream logic. Evaluate the 240 ms reset delay against system startup timing requirements. Verify that the SC-70-3 package fits within the available PCB real estate constraints.

Supervisors Part Context

This part belongs to the ADM803 series of microprocessor supervisors from Analog Devices. It complements other variants in the family that offer different thresholds or output types. The series is commonly used in embedded systems requiring reliable power-on reset functionality. It serves as a critical component for ensuring stable operation during power transitions.

Supervisors Replacement Considerations

Check for ADM803LAKSZ-REEL7 for open-drain output options. Verify ADM809RAKSZ-REEL7 for alternative threshold voltages. Confirm functional compatibility regarding reset delay and operating voltage ranges before substitution.
