DS1814CR-5/T&R

Supervisors Overview

The DS1814CR-5/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 5 V. The device provides power-fail detection with an overvoltage threshold of 4.5 V. It utilizes a push-pull output configuration supporting both active high and active low states. The reset delay time is specified at 200 ms, and the accuracy is maintained at 2.5%. Operating temperatures range from -40°C to +85°C, with a typical operating current of 15 µA.

Supervisors Feature Summary

• Integrated power-fail detection capability for monitoring supply status
• Configurable push-pull output supporting active high or active low logic states
• Fixed threshold voltage design eliminating external resistor requirements

Supervisors Applications

• Embedded system power supply supervision
• Microcontroller reset management
• Portable electronic device power integrity monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required voltage threshold and output polarity for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for single-channel power monitoring. Consider the 15 µA operating current for battery-sensitive designs. Verify that the SOT-23-5 package fits the board layout constraints. Confirm compatibility with the system's logic levels given the push-pull output options.

Supervisors Part Context

This component belongs to the DS1814 MicroMonitor family, designed for compact power management applications. It integrates precision reference and comparator circuits into a small surface-mount package. The series supports various threshold voltages and output configurations to accommodate different system requirements without external components.
