ADM810SART-REEL7

Supervisors Overview

The ADM810SART-REEL7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output driver with high-active reset logic. The device monitors a single input voltage against a threshold of 2.93 V, providing a reset delay time of 840 ms. Designed for surface-mount installation in an SC-70 package, it supports an operating temperature range from -40°C to +125°C. The component draws a typical operating current of 60 µA and lacks manual reset or watchdog timer functions.

Supervisors Feature Summary

• Provides reliable power system supervision through a dedicated voltage monitoring channel
• Features a push-pull output driver capable of sourcing and sinking current directly
• Ensures stable operation across wide industrial temperature ranges without external components

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered electronic devices
• Embedded system reset generation

Supervisors Procurement Notes

Verify the specific suffix 'S' indicates the 2.93 V threshold variant when ordering. Confirm the 'REEL7' designation matches required tape-and-reel specifications. Check current availability status as this part may be discontinued or subject to allocation. Ensure the SC-70 footprint aligns with PCB design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a low quiescent current and compact SC-70 footprint are required. It is suitable for applications needing a fixed 2.93 V threshold with an 840 ms delay. Consider alternatives if manual reset capability or a different threshold voltage is necessary. Verify that the push-pull output drive strength meets the load requirements of the target circuit.

Supervisors Part Context

This component belongs to the ADM810 series of simple reset supervisors. It is functionally similar to other variants like the ADM810MAKSZ but differs in package type and specific threshold voltage. The series provides basic power management supervision without complex features like watchdog timers.

Supervisors Replacement Considerations

Direct substitutes include ADM810MAKSZ-REEL7 (SC-70, 2.5V/3V/3.3V/5V options) and ADM810TARTZ-REEL7 (SOT-23-3, 3.08V). Verify threshold voltage compatibility and package dimensions before substitution.
