DS1814CR-5+T&R

Supervisors Overview

The DS1814CR-5+T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a threshold of 5 V and features active high/low push-pull outputs. The device includes power-fail detection and operates within a temperature range of -40°C to +85°C. It has a reset delay time of 200 ms, a maximum supply voltage of 5.5 V, and an operating current of 15 uA.

Supervisors Feature Summary

• Integrated power-fail detection capability for monitoring supply integrity
• Push-pull output configuration supporting both active high and active low logic states
• Compact SOT-23-5 surface-mount package design

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact electrical characteristics and pinout compatibility before integration. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the component meets required environmental standards for the intended application environment.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold with push-pull outputs is required. Consider the 15 uA operating current for low-power designs. Verify that the 200 ms reset delay aligns with system startup timing requirements. Compare against other DS1814 variants if different thresholds or output types are needed.

Supervisors Part Context

This part belongs to the DS1814 series of MicroMonitor circuits from Maxim Integrated. These devices provide simple voltage supervision in small packages. The series typically offers various threshold options and output configurations to suit different embedded applications requiring reliable power monitoring.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1814 family with matching thresholds and output types. Verify pinout compatibility with existing PCB layouts. Consult official datasheets for any functional differences between legacy and current production versions.
