ADM1817-R23ART-RL

Supervisors Overview

The ADM1817-R23ART-RL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor single power supply rails. It operates within a maximum supply voltage of 5.5 V and features a push-pull output type. The device provides a reset delay time of 250 ms and includes an overvoltage threshold of 3.15 V. It functions reliably across a temperature range from -40°C to +105°C with a typical operating supply current of 16 uA. The component is housed in a SOT-23-3 package.

Supervisors Feature Summary

• Monitors a single input voltage rail for undervoltage conditions
• Provides active-low reset signal via push-pull output
• Includes automatic reset generation upon power-up or brown-out events

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations may indicate different packaging or tape-and-reel specifications. Confirm availability status through authorized distributors, noting that specific reel quantities may vary. Ensure compliance with RoHS directives and check for any lifecycle notifications regarding discontinuation before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a low-power, single-channel supervisor with a fixed threshold is required. Compare the 250 ms reset delay against system startup timing requirements. Evaluate the SOT-23-3 package size constraints against PCB layout limitations. Consider the 16 uA quiescent current impact on battery life applications compared to higher-current alternatives.

Supervisors Part Context

This part belongs to the ADM1817 series of voltage supervisors. It shares functional similarities with other parts in the family but differs in specific threshold voltages and package options. The series is designed for cost-effective power monitoring solutions in consumer and industrial electronics.
