ADM810ZARTZ-REEL

Supervisors Overview

The ADM810ZARTZ-REEL is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.0 V to 5.5 V and features a push-pull output configuration with active-high reset assertion. The device monitors a specific threshold voltage of 2.63 V, ensuring system integrity during power fluctuations. It includes a minimum reset timeout delay of 140 ms to prevent premature reset assertions during power-up sequences. Designed for surface-mount installation in SOT-23-3 packages, it supports industrial temperature ranges from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable voltage supervision with a fixed 2.63 V threshold for critical power monitoring applications.
• Features a push-pull output stage capable of driving downstream logic directly without additional pull-up components.
• Ensures stable system initialization through a guaranteed minimum reset timeout delay of 140 ms.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact suffix designation against official Analog Devices documentation, as variations exist within the ADM810 family. Confirm package type and threshold voltage specifications match design requirements. Check current lifecycle status, as some variants may be discontinued or subject to limited availability. Ensure compatibility with existing PCB footprint and thermal management strategies.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-supply monitoring. Compare reset timeout characteristics against system power-up timing constraints. Evaluate package size limitations against available board space. Consider operating temperature range requirements for harsh environments.

Supervisors Part Context

This part belongs to the ADM810 series of simple reset generators designed for microprocessor systems. It offers a compact solution for power management without requiring external resistors or capacitors for threshold setting. The series provides various threshold options and package configurations to suit different design needs.

Supervisors FAQ

What is the reset output polarity?

The reset output is active-high, meaning it asserts high when the monitored voltage is below the threshold.

Does this device include a manual reset input?

No, the ADM810ZARTZ-REEL does not feature a manual reset input; it functions solely as a power-on reset generator.
