DS1814BR-5-U

Supervisors Overview

The DS1814BR-5-U is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.3V to 5.5V and features a fixed reset threshold voltage of 5V with a 5% tolerance. The device provides pushbutton manual reset functionality and includes an integrated watchdog timer. It utilizes a SOT-23-5 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for system fault detection
• Pushbutton manual reset capability
• Fixed 5V reset threshold voltage
• Single-channel power supply monitoring

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Industrial control unit protection
• Consumer electronics power integrity

Supervisors Procurement Notes

Verify the specific suffix 'U' indicates the tape-and-reel packaging format when sourcing components. Confirm that the manufacturer designation aligns with current Analog Devices or Maxim Integrated product lines, as corporate structures have evolved. Ensure the component meets RoHS compliance standards required for your manufacturing process before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 5V threshold is required for single-supervision applications. The inclusion of a watchdog timer distinguishes it from basic reset controllers. Verify that the SOT-23-5 footprint matches your PCB layout constraints. Consider the manual reset feature if user intervention capabilities are necessary for system recovery procedures.

Supervisors Part Context

This part belongs to the MicroMonitor family of supervisory circuits designed for reliable power management. It complements other variants in the series that offer different threshold voltages or additional monitoring channels. The device addresses common system stability issues by ensuring proper initialization and continuous voltage oversight during operation.

Supervisors Replacement Considerations

DS1814BR-5+T&R; serves as a verified alternative offering identical electrical characteristics with standard reel packaging.
