DS1814CR-10-U

Supervisors Overview

The DS1814CR-10-U is a single-channel supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a micromonitor with a voltage threshold of 4.375V, designed for simple reset and power-on reset applications. The device features push-pull outputs supporting both active high and active low configurations. It is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained electronic designs requiring reliable voltage supervision.

Supervisors Feature Summary

• Single-channel voltage monitoring capability
• Configurable push-pull output polarity
• Integrated power-on reset functionality

Supervisors Applications

• Microprocessor system supervision
• Power-on reset generation
• Voltage threshold monitoring circuits

Supervisors Procurement Notes

Verify the specific suffix 'U' corresponds to the SOT-23-5 package variant when sourcing. Confirm that the 4.375V threshold aligns with system requirements. Ensure compatibility with active high or low logic levels required by the target controller. Cross-reference manufacturer documentation for pinout accuracy before integration into final hardware designs.

Supervisors Selection Notes

Select this component for applications requiring a dedicated single-supervisor IC with configurable output states. The SOT-23-5 package offers a small footprint compared to larger alternatives. Consider the fixed 4.375V threshold against system operating voltages. Evaluate thermal performance within the intended operating environment to ensure stable supervision during transient conditions.

Supervisors Part Context

This part belongs to the Maxim Integrated supervisory circuit family, specifically designed for monitoring single voltage rails. It complements other multi-channel supervisors by providing a cost-effective solution for single-rail systems. The series includes variants with different thresholds and packages, allowing designers to tailor supervision strategies based on specific voltage requirements and board space constraints.

Supervisors Replacement Considerations

Direct substitutes may include other single-channel supervisors from the same manufacturer with compatible thresholds and packages. Verify electrical characteristics such as reset delay times and quiescent current when cross-referencing alternative parts. Ensure pinout compatibility if physical replacement is necessary without redesigning the PCB layout.
