DS1814AR-5-U

Supervisors Overview

The DS1814AR-5-U is a single-channel voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage with a threshold of 4.625V and provides an active high, push-pull output. The device features a reset timeout of 140ms and operates within a supply voltage range compatible with standard logic levels. Packaged in the SC-74A (SOT-753) surface-mount case, it is designed for reliable power management in embedded systems.

Supervisors Feature Summary

• Provides active high push-pull output signaling for system supervision
• Monitors a single voltage input channel for power integrity
• Utilizes compact SC-74A surface-mount packaging for space-constrained designs

Supervisors Applications

• Embedded system power monitoring
• Microcontroller reset circuitry
• Portable electronic device power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements to maintain reliability before soldering.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with active high output is required. Verify that the 4.625V threshold aligns with the target supply rail. Consider the 140ms reset delay relative to system startup timing requirements. Ensure the SC-74A footprint matches the PCB layout design.

Supervisors Part Context

This part belongs to the DS1814 series of voltage supervisors from Maxim Integrated, now part of Analog Devices. The series offers various threshold voltages and output configurations. The DS1814AR-5-U specifically denotes the 4.625V threshold variant in the SOT-753 package, distinguishing it from other pinouts and thresholds in the family.

Supervisors Replacement Considerations

Check for DS1814AR-5+T&R as a potential alternative configuration. Verify pin compatibility and electrical specifications against current design requirements before substitution.
