ADM1815-R23ARTZ-RL

Supervisors Overview

The ADM1815-R23ARTZ-RL is a supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor reset generator. It operates within a supply voltage range of 4V to 12.6V and features a fixed reset threshold level of 2.31V, making it suitable for monitoring lower-voltage rails or specific reference points. The device provides a push-pull or open-drain reset output signal to ensure reliable system initialization. Packaged in a compact SOT-23-3 form factor, it supports surface-mount installation and functions across an industrial temperature range from -40°C to +105°C. This component integrates essential voltage monitoring capabilities into a small footprint.

Supervisors Feature Summary

• Provides a dedicated reset signal output for microprocessor supervision
• Features a fixed 2.31V reset threshold for precise voltage monitoring
• Operates over an extended industrial temperature range

Supervisors Applications

• Microprocessor reset generation in embedded systems
• Voltage monitoring for low-voltage power supplies
• System supervision in portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix (R23ARTZ-RL) against the manufacturer's current datasheet to confirm the 2.31V threshold and package type. Ensure compatibility with your board's thermal requirements given the -40°C to +105°C operating range. Cross-reference the pinout configuration for SOT-23-3 packages to prevent soldering errors during assembly.

Supervisors Selection Notes

Select this component when a fixed 2.31V reset threshold is required rather than adjustable options. Consider the SOT-23-3 package size constraints and the need for a single-channel supervisor. Evaluate if the specified input voltage range covers your application's supply variations without requiring additional external components.

Supervisors Part Context

This part belongs to the ADM1815 series of supervisory circuits from Analog Devices. The series includes various variants with different reset thresholds and package options. The R23 designation specifically indicates the 2.31V threshold version. These devices are commonly used alongside other ADM18xx series parts for comprehensive power management solutions.

Supervisors Replacement Considerations

Direct substitutes include other ADM1815 variants with similar thresholds, such as ADM1815-R22ARTZ-RL (2.20V) or ADM1815-R25ARTZ-RL (2.50V), provided the threshold difference is acceptable. Verify pin compatibility and electrical specifications before substitution.
