ADM1818-R23ART-RL

Supervisors Overview

The ADM1818-R23ART-RL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It features an open-drain output and provides a reset signal that is active low. The device triggers at a threshold voltage of 2.31V with a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to 105°C and is housed in a surface-mount SOT-23-3 package. This component is classified as a simple reset/power-on-reset supervisor.

Supervisors Feature Summary

• Monitors a single voltage input for under-voltage conditions
• Generates a system reset signal upon detecting fault conditions
• Provides an open-drain output interface for flexible logic compatibility

Supervisors Applications

• Embedded systems requiring reliable power-up sequencing
• Microcontroller-based designs needing brown-out protection
• Portable electronics utilizing low-voltage battery supplies

Supervisors Procurement Notes

Verify the specific suffix 'R23' confirms the 2.31V threshold, as variants exist for other voltages. Confirm the 'ART' suffix corresponds to the SOT-23-3 package type required for your layout. Check current lifecycle status, as this part may be discontinued or subject to limited availability depending on the distributor source.

Supervisors Selection Notes

Select this component when a low-pin-count supervisor is needed for single-rail monitoring. Ensure the 2.31V threshold aligns with the target system's minimum operating voltage. Consider the open-drain output requirement for pull-up resistor implementation. Verify thermal performance meets the application's ambient temperature constraints within the specified industrial range.

Supervisors Part Context

This part belongs to the ADM1818 series of voltage supervisors from Analog Devices. The series offers various threshold voltages and package options to suit different design requirements. It is part of the broader portfolio of power management integrated circuits focused on system reliability and protection.

Supervisors Replacement Considerations

The ADM1818-R23AKSZ-R7 is documented as a parameter-equivalent substitute. Verify pinout and electrical specifications match before replacement.
