ADM1817-R23ART-RL7

Supervisors Overview

The ADM1817-R23ART-RL7 is a 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 threshold voltage of 2.31 V. The device provides a push-pull output with a reset delay time of 250 ms. It consumes a typical operating current of 16 uA and lacks manual reset, watchdog timer, or battery backup switch functions. The component is housed in an SOT-23-3 package and supports surface mount installation. It is rated for operation between -40 C and +105 C.

Supervisors Feature Summary

• Monitors single input voltage with precise threshold detection
• Generates system reset signal upon power failure or brown-out
• Operates with low quiescent current for energy efficiency

Supervisors Applications

• Embedded system power management
• Microcontroller reset generation
• Portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation to ensure correct threshold voltage and package type. Confirm availability status as distribution channels may list obsolete or limited stock items. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure compliance with RoHS directives if required for your specific application environment.

Supervisors Selection Notes

Select this component when a simple, low-power supervisor is needed for voltages up to 5.5 V. The 2.31 V threshold suits applications requiring monitoring of lower voltage rails. Consider the 250 ms delay for stable startup conditions. Verify that the SOT-23-3 package fits your PCB layout constraints. Ensure the absence of manual reset meets your design requirements.
