ADM1815-R22AKSZ-RL

Supervisors Overview

The ADM1815-R22AKSZ-RL is a microprocessor reset circuit manufactured by Analog Devices Inc. It operates within an extended temperature range of -40°C to +105°C and utilizes a SC70 (KS-3) surface-mount package with three pins. The device monitors a single input voltage channel and provides a low-active reset signal via a push-pull, totem pole output. The specific threshold voltage for this variant is 2.18 V. The maximum supply voltage rating is 5.5 V, ensuring compatibility with standard logic levels while providing reliable system supervision.

Supervisors Feature Summary

• Provides dedicated reset control for microprocessor systems
• Features a compact SC70-3 surface-mount footprint
• Delivers active-low reset signals with push-pull drive capability

Supervisors Applications

• Microprocessor reset circuits
• System voltage supervision
• Power management IC monitoring

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm the 2.18 V threshold specification. Ensure the SC70-3 package matches your PCB layout requirements. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference the full part number to distinguish from other ADM1815 variants with different voltage thresholds or output types.

Supervisors Selection Notes

Select this component when a fixed 2.18 V threshold is required for system supervision. The push-pull output offers stronger drive capability compared to open-drain alternatives. The wide operating temperature range supports industrial applications. Verify that the single-channel monitoring meets the design needs without requiring additional supervisory channels.

Supervisors Part Context

This part belongs to the ADM1815 series of power supervisors designed for simple reset generation. It serves as a fundamental building block for ensuring stable operation in digital systems. The series includes various threshold voltages to accommodate different supply rails. The SC70 package allows for space-constrained designs.

Supervisors Replacement Considerations

ADM1815-R22AKSZ-R7 is a reel-packaged equivalent with identical electrical specifications. Other ADM1815 variants may serve as substitutes if the threshold voltage matches the application requirement. Verify pinout compatibility before replacing.
