ADM810SAKSZ-REEL

Supervisors Overview

The ADM810SAKSZ-REEL7 is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and monitors input voltages with thresholds including 2.5 V, 3 V, 3.3 V, and 5 V. The device features a push-pull/totem pole output driver with high-active reset logic. It provides a minimum reset timeout delay of 140 ms and functions reliably across an industrial temperature range of -40°C to +125°C. Packaged in a compact SC-70 (SOT-23-3) surface-mount housing, it ensures stable system operation under varying power conditions.

Supervisors Feature Summary

• Provides hardware-based monitoring for single power rails to ensure reliable microprocessor initialization
• Features a push-pull output driver capable of sourcing and sinking current for robust reset signal transmission
• Includes a fixed internal reset timeout delay to prevent premature processor activation during power-up sequences

Supervisors Applications

• Embedded systems requiring precise power-on reset sequencing
• Portable electronic devices operating on battery or low-voltage DC supplies
• Industrial control units needing wide temperature range supervision

Supervisors Procurement Notes

Verify the specific suffix code against official Analog Devices documentation to confirm the exact reset threshold voltage, as the base part number covers multiple variants. Confirm package integrity and RoHS compliance status through authorized distributors. Ensure the ordering information matches the required electrical specifications for your design.

Supervisors Selection Notes

Select this component when a simple, low-pin-count supervisor is needed for single-rail monitoring. Verify that the available threshold options align with your target supply voltage. Consider the push-pull output capability if driving loads directly without external pull-ups. Check thermal requirements against the specified operating temperature range.

Supervisors Part Context

This component belongs to the ADM8xx series of supervisory circuits from Analog Devices. These parts are designed to replace discrete resistor-capacitor networks and manual reset switches, offering higher accuracy and smaller footprint. The series supports various packages and threshold combinations for diverse embedded applications.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Consult Analog Devices application notes or distributor cross-reference tools for compatible alternatives based on specific threshold and package requirements.
