ADM1818-10ART-RL7

Supervisors Overview

The ADM1818-10ART-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It features a push-pull output configuration with an active-high reset signal, ensuring reliable system initialization. The device operates within a maximum supply voltage of 5.5 V and includes a fixed reset delay time of 250 ms to accommodate power-up transients. It supports threshold voltages including 10 V variants for specific high-voltage monitoring needs, though standard operation typically aligns with lower thresholds. The component is housed in a compact SOT-23-3 surface-mount package, suitable for space-constrained designs.

Supervisors Feature Summary

• Monitors a single input voltage channel with precise threshold detection capabilities
• Provides a stable active-high reset signal via a push-pull output stage
• Incorporates a fixed 250 ms reset delay to manage power-up sequences effectively

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Battery-powered equipment voltage monitoring
• Industrial control system power management

Supervisors Procurement Notes

Verify the exact suffix and threshold variant against official Analog Devices documentation before procurement, as ordering codes determine specific electrical parameters. Confirm availability status through authorized distributors, as this part may be subject to limited supply or discontinuation notices. Ensure the selected package matches the PCB footprint requirements and validate RoHS compliance for environmental standards.

Supervisors Selection Notes

Select this component when a simple, low-power voltage supervisor with an active-high output is required. Consider the 250 ms reset delay duration relative to the target system's power-up timing constraints. Evaluate the SOT-23-3 package size against available board space. Ensure the monitored voltage range aligns with the specific threshold version chosen from the product family.

Supervisors Part Context

This part belongs to the ADM1818 series of voltage supervisors, which are designed for critical system protection. The series offers various threshold options and output configurations to suit different application requirements. The ADM1818-10ART-RL7 specifically denotes the reel-packaged version in the SOT-23-3 package, intended for automated surface-mount assembly processes.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for parameter-equivalent alternatives if this specific part number is unavailable. Verify that any substitute maintains identical output polarity, reset delay characteristics, and package dimensions to ensure mechanical and electrical compatibility without redesign.
