ADM1816-R23AKSZ-R7

Supervisors Overview

The ADM1816-R23AKSZ-R7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.31 V. The device provides a reset signal with a typical delay time of 250 ms. It is housed in an SC-70-3 surface-mount package and supports open drain or push-pull output configurations. The component is designed for operation across an extended temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Provides reliable power-on reset functionality with a fixed 2.31 V threshold
• Offers flexible output drive options including open drain and push-pull modes
• Ensures stable system recovery with a defined 250 ms reset delay

Supervisors Applications

• Microprocessor reset circuits
• Portable equipment power management
• Battery-powered systems supervision

Supervisors Procurement Notes

Verify the specific suffix 'R7' indicates tape and reel packaging when sourcing. Confirm the 2.31 V threshold variant matches the design requirement, as other thresholds exist in the series. Check current availability status as distribution may vary. Ensure the SC-70-3 footprint aligns with the PCB layout. Validate RoHS compliance documentation for the specific batch.

Supervisors Selection Notes

Select this part when a fixed 2.31 V threshold is required for low-voltage monitoring. Choose the SC-70-3 package for space-constrained designs. Consider the output type (open drain vs. push-pull) based on interface requirements. Verify that the 250 ms delay meets the system's startup timing constraints. Ensure the operating temperature range covers the application environment.

Supervisors Part Context

This component belongs to the ADM1816 series of microprocessor reset circuits from Analog Devices. The series includes variants with different threshold voltages and output configurations. The R7 suffix typically denotes tape and reel packaging for automated assembly. These devices are designed to monitor supply voltages and generate reset signals for digital logic.

Supervisors Replacement Considerations

The ADM1818-R23AKSZ-R7 is listed as a parameter-equivalent replacement. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative maintains the same SC-70-3 package and 2.31 V threshold.
