ADM810MAKSZ-REEL7

Supervisors Overview

The ADM810MAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output driver with active-high reset assertion. The device provides specific threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V options. Key electrical parameters include a maximum reset delay time of 840 ms, a typical operating supply current of 60 uA, and an overvoltage threshold of 4.45 V. It functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides manual reset-free supervision with active-high push-pull output
• Supports multiple fixed voltage thresholds for various system requirements
• Operates with low quiescent current consumption
• Rated for industrial temperature ranges up to 125°C

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Portable electronic device power management
• Industrial control board reset generation

Supervisors Procurement Notes

Verify the specific voltage threshold variant required, as the base part number covers multiple options (2.5V, 3V, 3.3V, 5V). Confirm the suffix matches the desired threshold. Check current availability status as distribution may be limited. Ensure the SC-70-3 package fits the PCB layout constraints. Validate RoHS compliance documentation if required for the target market.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor is needed without watchdog or manual reset features. Compare the 840 ms delay against system startup timing requirements. Consider the 60 uA current draw for battery life calculations. Verify that the available threshold voltages align with the monitored rail levels. Evaluate the SC-70-3 footprint against alternative packages like SOT-23-3 if space permits.
