ADM1817-R23AKSZ-R7

Supervisors Overview

The ADM1817-R23AKSZ-R7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.31 V. The device provides a push-pull output type with a reset delay time of 250 ms. It functions as a single-input monitor without manual reset or watchdog timer capabilities. The component supports surface mount installation in an SOT-23-3 package and maintains operation across a temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems
• Features a push-pull output driver for direct logic interface
• Operates with low quiescent current consumption
• Includes internal reset delay to ensure stable power-up sequencing

Supervisors Applications

• Microprocessor reset generation
• Battery-powered system monitoring
• Portable electronic devices
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the R23AKS designation corresponds to the 2.31 V threshold variant. Check current lifecycle status as distribution availability may vary. Ensure compatibility with existing PCB footprint requirements for the SOT-23-3 package. Validate RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed 2.31 V threshold is required for system supervision. Consider the push-pull output if active high/low signaling is preferred over open-drain configurations. Evaluate the 250 ms reset delay against system startup timing requirements. Compare power consumption metrics against other supervisory ICs in the portfolio for battery life optimization.

Supervisors Part Context

This part belongs to the ADM1817 series of voltage supervisors designed for reliable system monitoring. The series offers various threshold options to accommodate different rail voltages. The R7 suffix typically denotes tape and reel packaging for automated assembly processes. Analog Devices integrates these components into broader power management solutions for embedded applications.
