DS1814AR-10+T&R

Supervisors Overview

The DS1814AR-10+T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage input with a threshold of 5V and features a push-pull output that supports both active high and active low configurations. The device provides a reset delay time of 200 ms and includes power-fail detection capabilities. It operates within a supply voltage range up to 5.5 V, maintains an accuracy of 2.5%, and consumes 15 uA of operating current. The component is housed in a SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring of a single voltage rail with configurable active high or active low push-pull outputs.
• Integrates power-fail detection to warn the system of impending power loss without requiring external components.
• Delivers a fixed 200 ms reset delay to ensure stable operation during power-up transients.

Supervisors Applications

• Monitoring 5V logic supplies in embedded systems
• Power management in industrial control units
• Supervision of microprocessor voltage rails

Supervisors Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the ordering part number matches the required package and temperature grade for your design.

Supervisors Selection Notes

Select this component when a fixed 5V threshold with 200 ms delay is required. The push-pull output allows flexible interface with various logic families. Verify that the 2.5% accuracy meets system tolerance requirements and that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the DS1814 series of MicroMonitor circuits designed for simple voltage supervision. It serves as a cost-effective solution for basic power management tasks where complex configuration is unnecessary. The series is widely used in consumer and industrial electronics for reliable power sequencing.

Supervisors Replacement Considerations

Consult official datasheets for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the 5V threshold and 200 ms delay specifications to ensure functional equivalence.
