DS1814AR-10/T&R

Supervisors Overview

The DS1814AR-10+T&R is a voltage monitor integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 5 V with an accuracy of 2.5%. The device provides active high, active low, and push-pull output configurations. It includes power failure detection capabilities and has a reset delay time of 200 ms. The component functions without manual reset or watchdog timer features and lacks battery backup switching. It is designed for surface mount installation in SOT-23-5 packages.

Supervisors Feature Summary

• Provides multi-output configuration including active high, active low, and push-pull signals
• Integrates power failure detection functionality
• Operates without requiring manual reset inputs or external watchdog timers

Supervisors Applications

• Monitoring 5 Volt and 3.3 Volt microsystems
• Power supply supervision in embedded systems
• Voltage threshold detection in industrial control circuits

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited supply or factory special order conditions. Confirm package type matches SOT-23-5 requirements. Ensure compatibility with 5.5 V maximum operating limits. Check for RoHS compliance documentation. Validate that the specific suffix corresponds to reel packaging specifications.

Supervisors Selection Notes

Select this component when multi-state output flexibility is required alongside power failure monitoring. The absence of a watchdog timer simplifies design if external timing is preferred. Verify that the 200 ms reset delay meets system startup timing requirements. Ensure the 2.5% accuracy specification aligns with voltage tolerance needs. Confirm surface mount assembly capabilities for the SOT-23-5 footprint.

Supervisors Part Context

This part belongs to the DS1814CR series of voltage monitors from Maxim Integrated. It shares functional similarities with other members like the DS1819 but offers distinct output configurations. The series focuses on simple voltage supervision without complex programmability. It serves as a dedicated supervisor for standard logic voltage levels.

Supervisors Replacement Considerations

DS1814CR-10+T&R is a confirmed substitute within the same series offering identical core monitoring functions.
