ADM1818-10AKSZ-RL7

Supervisors Overview

The ADM1818-10AKSZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features a fixed threshold voltage of 4.62 V for the monitored input. The device provides an active low, open-drain reset output with a typical reset delay time of 100 ms minimum. It is housed in a SC-70-3 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides reliable power-on reset functionality with a fixed threshold voltage.
• Features an active low open-drain output compatible with various logic families.
• Supports extended industrial temperature ranges for robust operation.

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Portable instrumentation power control

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm that the specific suffix matches the required threshold voltage and packaging format. Ensure compliance with RoHS directives and check for any discontinuation notices or lifecycle status updates prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for systems operating up to 5.5 V. Consider the SC-70-3 package for space-constrained designs. Evaluate the open-drain output configuration against system logic requirements. Verify thermal performance within the specified industrial temperature range during design integration.

Supervisors Part Context

This part belongs to the ADM1818 series of simple reset supervisors. It complements other variants in the family that offer different threshold voltages or output configurations. The series is designed for applications requiring basic power management supervision without complex watchdog or manual reset features.

Supervisors Replacement Considerations

The ADM1818-R23AKSZ-R7 is documented as a parameter-equivalent substitute. Verify that the threshold voltage difference aligns with system requirements before substitution.
