ADM1811-5AKSZ-RL7

Supervisors Overview

The ADM1811-5AKSZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides a reset signal when the supply drops below or exceeds specific thresholds. The device operates within a maximum supply voltage of 5.5 V and features a reset delay time of 250 ms. It is available in an SC-70-3 surface-mount package. Threshold voltages include 2.5 V, 3 V, 3.3 V, and 5 V. The output type supports open drain and push-pull configurations.

Supervisors Feature Summary

• Provides microprocessor reset functionality with simple power-on reset capabilities
• Monitors a single voltage input for under-voltage and over-voltage conditions
• Offers flexible output drive options including open drain and push-pull modes

Supervisors Applications

• Microprocessor system supervision
• Power-on reset generation for digital circuits
• Voltage monitoring in portable electronic devices

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Check current lifecycle status as availability may be limited. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during soldering processes.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with configurable threshold options is required. Consider the SC-70-3 package size for space-constrained designs. Evaluate the 250 ms reset delay against system startup timing requirements. Verify that the 5.5 V maximum operating voltage aligns with the target power rail specifications.

Supervisors Part Context

This part belongs to the ADM1811 series of supervisory circuits from Analog Devices. It is designed for applications requiring reliable voltage monitoring in compact form factors. The series typically includes variants with different threshold voltages and output configurations to suit various logic families and power supply standards.

Supervisors Replacement Considerations

Check for parameter-equivalent alternatives such as the ADM1818-R23AKSZ-R7 if the original part is obsolete. Verify pin compatibility and electrical specifications before substitution.
