DS1812-15+T&R

Supervisors Overview

The DS1812-15+T&R is a single-channel voltage supervisor IC manufactured by Analog Devices Inc. under the Maxim Integrated brand, packaged in SOT-23-3. It operates within a supply voltage range of 4.75V to 5.25V and features a fixed reset threshold of 4.62V. The device provides a push-pull active-high reset output with a minimum timeout of 100ms. It supports surface-mount installation and functions across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple power-on reset functionality for monitoring a single voltage channel
• Features a push-pull or图腾柱 output structure for active-high reset signaling
• Includes a guaranteed minimum reset timeout period to ensure stable system initialization

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered systems requiring reliable power-on reset sequences
• Embedded control circuits needing voltage threshold monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm electrical characteristics and package type. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the component meets required environmental certifications such as RoHS compliance before integration into final designs.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is required for standard 5V logic systems. The SOT-23-3 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 100ms minimum timeout duration to align with the startup requirements of the target processor or memory devices.

Supervisors Part Context

This part belongs to the EconoReset series, designed for cost-effective voltage monitoring applications. It serves as a fundamental building block for ensuring system reliability by detecting undervoltage conditions and initiating appropriate reset actions without complex configuration.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same SOT-23-3 pinout and 4.62V threshold specification to guarantee compatibility.
