ADM812RARTZ-REEL

Supervisors Overview

The ADM812RARTZ-REEL is a supervisory circuit manufactured by Analog Devices Inc., designed for voltage monitoring applications. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 2.63 V. The device provides a push-pull output with a reset delay time of 240 ms. It is housed in a SOT-143-4 package and supports an operating temperature range from -40°C to +125°C. The component has a typical quiescent current of 60 µA and offers 1.5% accuracy.

Supervisors Feature Summary

• Provides reliable voltage monitoring with a fixed reset threshold
• Features a push-pull output driver for direct interface compatibility
• Includes a built-in manual reset input for system control
• Operates across an extended industrial temperature range

Supervisors Applications

• Portable equipment power management
• Microprocessor system supervision
• Battery-powered devices
• Automotive electronics monitoring

Supervisors Procurement Notes

Verify the specific suffix REEL7 against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the SOT-143-4 package variant matches the design requirements. Cross-reference the 2.63 V threshold with system voltage rails to guarantee proper reset timing. Confirm RoHS compliance status through the manufacturer's latest documentation before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for systems powered between 1.2 V and 5.5 V. The SOT-143-4 package is suitable for space-constrained designs. Consider the 240 ms reset delay for applications requiring stable power-up sequences. The low quiescent current makes it appropriate for battery-operated devices where power efficiency is critical.

Supervisors Part Context

The ADM812 belongs to the ADM81x series of voltage supervisors from Analog Devices. This family includes variants with different thresholds and packages. The RARTZ suffix indicates a specific pinout and package configuration within the series. These devices are commonly used in consumer, industrial, and automotive applications for power integrity.

Supervisors Replacement Considerations

Check for ADM811 or ADM813 equivalents if different thresholds are needed. Verify pin compatibility with other SOT-143-4 supervisors. Ensure replacement parts maintain the same reset delay and output type characteristics.
