DS1833-15/T&R

Supervisors Overview

The DS1833-15/T&R is a supervisory circuit from the EconoReset series manufactured by Analog Devices Inc./Maxim Integrated. It functions as a simple reset or power-on-reset monitor designed to ensure system stability during voltage fluctuations. The device features a fixed threshold voltage of 4.625V, allowing it to monitor a single input channel effectively. It provides a high-active reset output with a minimum timeout duration of 250ms to prevent premature resets. The component operates within a temperature range of -40°C to +85°C and is housed in a TO-92-3 package.

Supervisors Feature Summary

• Fixed threshold voltage monitoring for stable power supervision
• High-active reset output configuration
• Minimum 250ms reset timeout duration

Supervisors Applications

• Embedded systems requiring reliable power-on reset sequences
• Microcontroller-based designs needing voltage supervision
• Industrial control units operating in extended temperature ranges

Supervisors Procurement Notes

Verify current availability status as this part may be subject to limited supply or end-of-life conditions. Confirm that the TO-92-3 through-hole package aligns with your PCB layout requirements. Ensure compatibility with the 4.625V threshold for your specific application voltage levels before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is required without programmable options. The TO-92-3 package suits through-hole assembly processes. Consider the 250ms timeout requirement against your system's startup time needs. Verify that the high-active output logic matches your microcontroller's reset pin polarity requirements.

Supervisors Part Context

This part belongs to Maxim Integrated's EconoReset family, which offers cost-effective supervisory solutions. The DS1833 series provides basic reset functionality with fixed thresholds. The T&R suffix indicates tape-and-reel packaging, though the base DS1833-15 typically uses bulk packaging for TO-92 packages. This series is designed for applications where precise programmability is unnecessary.
