ADM1815-R23AKS-RL7

Supervisors Overview

The ADM1815-R23AKS-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It features an open-drain or open-collector output with a low-active reset signal and a minimum reset timeout of 100ms. The device operates within a temperature range of -40°C to 105°C (TA) and supports a threshold voltage of 2.31V. Packaged in SC-70-3 (SOT-323) for surface-mount installation, this component belongs to the ADM1810-13/ADM1815-18 series. The part status is listed as obsolete.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage rails
• Features open-drain or open-collector output configuration
• Supports manual reset input capability

Supervisors Applications

• Microcontroller system supervision
• Embedded controller power monitoring
• Portable electronic device voltage tracking

Supervisors Procurement Notes

This specific part number is officially discontinued and no longer manufactured by Analog Devices Inc. Verification of availability should focus on finding parameter-equivalent replacement components from the same manufacturer family. Procurement efforts must prioritize checking current stock levels of valid substitutes rather than sourcing the original obsolete part number directly.

Supervisors Selection Notes

Designers requiring this function should evaluate the parameter-equivalent ADM1818-R23AKSZ-R7 as a direct substitute. Selection criteria must ensure compatibility with the required 2.31V threshold, SC-70-3 package dimensions, and industrial temperature range specifications. Verify that the replacement maintains the necessary reset timeout characteristics and output drive capabilities for the target application circuit.

Supervisors Part Context

The ADM1815 series represents a line of voltage supervisory circuits intended for protecting sensitive electronics against under-voltage conditions. These devices are engineered to provide reliable reset signals when power supplies drop below specified thresholds. The R23 suffix indicates a fixed 2.31V threshold variant, while the KS-RL7 designation specifies the SC-70-3 package and reel packaging format used for automated assembly processes.

Supervisors Replacement Considerations

The parameter-equivalent substitute is ADM1818-R23AKSZ-R7.
