ADM1816-R22ART-RL7

Supervisors Overview

The ADM1816-R22ART-RL7 is a micropower voltage supervisor manufactured by Analog Devices Inc. This specific variant features a fixed output threshold of 2.2V, ensuring reliable monitoring for low-voltage digital systems. It operates within an extended industrial temperature range and utilizes an SOT-23 surface-mount package to minimize board space. The device provides a reset signal with a guaranteed delay time to allow power supply stabilization before asserting the reset line.

Supervisors Feature Summary

• Micropower consumption design suitable for battery-operated applications
• Fixed 2.2V threshold accuracy for precise voltage monitoring
• Manual reset input capability for system control flexibility

Supervisors Applications

• Portable electronic devices requiring low standby current
• Microcontroller power supply monitoring circuits
• Battery management systems with strict voltage thresholds

Supervisors Procurement Notes

Verify the exact suffix ART-RL7 against the manufacturer's official ordering guide to confirm packaging and tape-and-reel specifications. Ensure the thermal performance requirements align with the SOT-23 package limitations for your specific application environment. Cross-reference the date code and lot number if traceability is required for quality assurance protocols.

Supervisors Selection Notes

Select this component when a fixed 2.2V supervision level is necessary for microcontroller or memory protection. Consider the manual reset pin functionality if external control over the reset state is needed. Evaluate the quiescent current requirements against the total system budget to ensure efficient power management in portable designs.

Supervisors Part Context

This part belongs to the ADM1816 family of voltage supervisors designed for low-power applications. The family offers various threshold voltages and package options to suit different system requirements. The R22 designation specifically indicates the 2.2V trip point, distinguishing it from other variants in the series with different voltage references.

Supervisors Replacement Considerations

Check for direct cross-reference parts with identical 2.2V thresholds and SOT-23 packaging. Verify that any substitute maintains the same manual reset functionality and quiescent current characteristics. Ensure compatibility with existing PCB footprints and electrical parameters before implementation.
