DS1833-10+T&R

Supervisors Overview

The DS1833-10+T&R is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.0V to 6.0V and features a fixed threshold voltage of 4.375V for power monitoring. The device provides a manual reset capability, allowing users to trigger a system reset via an external pushbutton. It utilizes an open-drain output configuration with active-low assertion and includes a programmable reset timeout delay ranging from 50ms to 1400ms. Designed for surface-mount applications, it is housed in a compact SOT-23-5 package and supports operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset functionality for user-initiated system control alongside automatic power-fail detection.
• Features a configurable reset timeout delay to accommodate various system startup requirements.
• Provides an open-drain active-low output compatible with standard digital logic interfaces.

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Embedded systems needing manual reset inputs
• Industrial control units operating in harsh environments

Supervisors Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the required reset timeout and package type. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the component marking code with the manufacturer's guide to prevent counterfeit substitution during assembly.

Supervisors Selection Notes

Select this component when a single-supply monitor with manual reset is required. Compare the fixed 4.375V threshold against target rail voltages. Evaluate the SOT-23-5 footprint against available PCB space. Consider the open-drain output limitations regarding pull-up resistor requirements. Verify that the adjustable timeout meets the microcontroller startup timing specifications.

Supervisors Part Context

This part belongs to the DS1833 series of economical voltage supervisors designed for cost-sensitive applications. It serves as a simplified alternative to complex multi-channel sequencers. The series focuses on essential protection functions without additional communication interfaces. It complements the broader portfolio of Maxim Integrated power management solutions for basic system supervision needs.

Supervisors Replacement Considerations

Consult the official cross-reference list for verified equivalents. Check pin-to-pin compatibility before substituting. Verify that replacement parts maintain the same threshold voltage and package dimensions. Ensure the alternative supports the required manual reset feature.
