DS1815-5+T&R

Supervisors Overview

The DS1815-5+T&R is a supervisory circuit manufactured by Analog Devices Inc. (formerly Maxim Integrated). It functions as an EconoReset device designed to monitor power supply voltages and generate reset signals for microprocessors and digital systems. The component ensures system reliability by detecting voltage drops and initiating appropriate reset sequences. It is available in a tape and reel packaging format, designated by the suffix T&R, which facilitates automated assembly processes in high-volume manufacturing environments.

Supervisors Feature Summary

• Provides reliable power-supply supervision with push-pull output capability
• Designed for low-voltage operation within specified thresholds
• Compact surface-mount package suitable for space-constrained designs

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered equipment power monitoring
• Industrial control system supervision

Supervisors Procurement Notes

Verify the specific revision level and manufacturer lot codes upon receipt. Confirm that the tape and reel specifications match your pick-and-place machine requirements. Ensure the component matches the original datasheet electrical characteristics before integration into production lines.

Supervisors Selection Notes

Select this component when a dedicated supervisor with push-pull output is required for low-voltage applications. Consider the operating voltage range and reset delay characteristics relative to the target system's power-up sequence. Evaluate the SOT23-3 package constraints against available board space.
