ADM810LARTZ-REEL7

Supervisors Overview

The ADM810LARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 2.63 V. The device provides a push-pull output with active-high logic, ensuring reliable signal integrity. It includes a minimum reset timeout delay of 140 ms to accommodate power-up sequences. The component supports surface-mount installation in an SOT-23-3 package and functions reliably across an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides active-high push-pull reset signaling for monitored voltage rails
• Features a fixed 2.63 V threshold for precise under-voltage detection
• Includes a guaranteed minimum 140 ms reset timeout delay

Supervisors Applications

• Microprocessor system power supervision
• Battery-operated equipment voltage monitoring
• Portable instrumentation power management

Supervisors Procurement Notes

Verify the specific suffix 'L' indicates the 2.63 V threshold variant when sourcing. Confirm the 'REEL7' designation corresponds to tape-and-reel packaging requirements for automated assembly lines. Ensure compatibility with SOT-23-3 footprint constraints during PCB layout. Check current availability status as distribution may be limited or subject to allocation.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for systems operating between 1 V and 5.5 V. The push-pull output eliminates the need for external pull-up resistors, simplifying design. Consider the 140 ms timeout duration against system power-up timing requirements. Verify that the SOT-23-3 package size fits within the available board space constraints.

Supervisors Part Context

This part belongs to the ADM810 series of microprocessor supervisors from Analog Devices. It is functionally related to other variants in the family that offer different threshold voltages or manual reset capabilities. The series is designed for general-purpose voltage monitoring in embedded applications requiring simple, low-component-count supervision solutions.

Supervisors Replacement Considerations

Direct substitutes include other ADM810 variants with matching thresholds or compatible supervisor ICs from Analog Devices offering similar push-pull outputs and SOT-23-3 packaging. Verify electrical parameters such as threshold voltage and timeout delays before substitution.
