DS1814BR-10-U

Supervisors Overview

The DS1814BR-10-U is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input and provides reset signals with active high and active low push-pull outputs. The device operates within a supply voltage range of 2.7 V to 5.5 V and features a typical reset delay time of 200 ms. It is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides dual active high and active low push-pull reset outputs for flexible system integration
• Features nonvolatile memory to retain configuration settings during power loss
• Includes manual reset capability via an external pushbutton input

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microcontroller reset circuits
• Industrial control equipment monitoring

Supervisors Procurement Notes

Verify the specific suffix 'U' indicates the tape-and-reel packaging format when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental declarations may vary by production batch. Ensure the component matches the exact pinout and electrical specifications required for your design before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both active-high and active-low outputs is required. The inclusion of nonvolatile memory allows for persistent configuration without external storage. Consider the SOT-23-5 package size for space-constrained designs and verify that the 200 ms reset delay meets the timing requirements of the target microcontroller or logic circuit.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for voltage supervision applications. It integrates supervisory functions with nonvolatile memory capabilities, distinguishing it from basic reset controllers. The series is commonly used in portable and industrial electronics where power integrity and configuration retention are critical.

Supervisors Replacement Considerations

DS1814CR-10+T&R is a verified substitute offering identical functionality in a compatible SOT-23-5 package.
