ADM812SARTZ-REEL

Supervisors Overview

The ADM812SARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power rails and generate reset signals. It operates within a supply voltage range of up to 5.5 V and features a manual reset input for user-initiated control. The device provides a push-pull output type and includes a fixed reset delay time of 560 ms to ensure stable operation during power transitions. Available in an SOT-143-4 surface-mount package, it supports threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V. The component draws a typical operating supply current of 15 uA and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides manual reset capability for controlled system initialization
• Features a push-pull output stage for robust signal driving
• Includes a fixed reset delay timer to prevent premature resets

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered equipment monitoring
• Portable instrumentation systems

Supervisors Procurement Notes

Verify the specific suffix configuration against official documentation to confirm exact threshold voltage selection, as variations exist within the series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may differ between production batches. Ensure the ordering information matches the required package style and thermal specifications for your application environment.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit with manual reset functionality is required. Consider the available threshold voltage options to match the monitored rail accurately. Evaluate the SOT-143-4 package constraints regarding board space and thermal dissipation capabilities relative to the 200 mW power dissipation rating.

Supervisors Part Context

This part belongs to the ADM812 series of voltage supervisors from Analog Devices. The series offers various threshold options and packaging styles to suit different embedded design requirements. The ADM812 family is characterized by low quiescent current consumption and reliable performance in industrial and commercial environments.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same series that offer different threshold voltages if the current specification does not match the target rail.
