DS1814BR-10+T&R

Supervisors Overview

The DS1814BR-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 reset delay time of 200 ms. The device operates within a supply voltage range up to 5.5 V, with an accuracy of 2.5%. It draws a working power current of 15 uA and includes power-fail detection capabilities. The component is housed in a SOT-23-5 surface-mount package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates power-fail detection for monitoring supply integrity
• Provides push-pull output configuration with active high and low states
• Includes manual reset capability for system control

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microcontroller-based designs needing brown-out protection
• Industrial control units operating in varying thermal environments

Supervisors Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing, as Analog Devices and Maxim Integrated product lines may have distinct ordering codes. Confirm that the component matches the required SOT-23-5 package dimensions and electrical specifications for your design. Ensure compatibility with the target voltage thresholds and operational temperature ranges before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 5V threshold with precise 200 ms reset timing is required. The push-pull output allows direct interfacing with logic inputs without external pull-ups. Consider the low quiescent current for battery-sensitive applications. Verify that the manual reset feature aligns with the system's safety requirements and that the SOT-23-5 footprint fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the DS1814 series of MicroMonitor circuits designed for voltage supervision. It serves as a dedicated power management solution for ensuring stable operation in digital systems. The series is characterized by its ability to detect under-voltage conditions and initiate resets or alerts accordingly. It complements other supervisory components by offering specific threshold options and output configurations tailored for various industrial and commercial applications.
