ADM811SARTZ-REEL7

Supervisors Overview

The ADM811SARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor reset generator. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.93 V. The device provides an active low output signal with a reset delay time of 560 ms. It supports manual reset functionality and lacks watchdog or battery backup switches. Packaged in a SOT-143-4 surface-mount case, it draws a typical operating current of 15 uA and functions reliably between -40°C and +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 2.93 V threshold for reliable system monitoring
• Features active low push-pull output compatible with standard digital logic interfaces
• Includes manual reset capability allowing external control over the reset state
• Operates with ultra-low quiescent current suitable for power-sensitive applications

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered equipment voltage monitoring
• Portable electronics power management
• Industrial control system supervision

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm specific threshold voltage requirements match the fixed 2.93 V specification. Ensure thermal management aligns with the specified operating temperature range. Check for RoHS compliance documentation if required by project standards. Validate package integrity upon receipt to ensure SOT-143-4 pin alignment.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required rather than adjustable options. Consider the active low output polarity against system logic requirements. Evaluate the 560 ms delay against processor startup timing needs. Compare power consumption benefits against higher current alternatives. Verify manual reset necessity versus automatic-only operation preferences.

Supervisors Part Context

Part of the ADM811 series from Analog Devices, focusing on single-input voltage supervision. The series offers various threshold options across different suffixes. This specific variant targets applications needing precise mid-range voltage monitoring. It complements other ADM8xx family members offering different features like watchdog timers.

Supervisors Replacement Considerations

Check ADM811 variants with different threshold voltages if 2.93 V is unsuitable. Consider ADM811SART-REEL7 for push-pull output compatibility if active low is not required. Verify ADM811ZARTZ-REEL7 for lower threshold applications at 2.32 V. Ensure pinout compatibility remains consistent across SOT-143-4 packages.
