DS1833-5+

Supervisors Overview

The DS1833-5+ is a voltage supervisory circuit from the EconoReset series, designed to monitor a single input channel. It features a threshold voltage of 4.625 V and an overvoltage threshold of 4.74 V. The device provides an active high, open-drain output with a reset delay time of 350 ms. Operating within a supply voltage range up to 5.5 V, it consumes 50 uA of working power. The component supports through-hole installation in a TO-92-3 package and functions reliably across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored voltage rails
• Features an active high, open-drain output configuration
• Includes power failure detection capability without manual reset or watchdog timer

Supervisors Applications

• Monitoring microprocessor supply voltages
• Ensuring system stability during power-up and power-down sequences
• Protecting embedded systems against undervoltage conditions

Supervisors Procurement Notes

Verify RoHS compliance status carefully as documentation indicates conflicting information regarding environmental standards. Confirm current availability as the product lifecycle status is listed as obsolete. Ensure the specific suffix matches the required pinout and electrical characteristics before ordering.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor with an active high output is required. Consider the 350 ms reset delay and 4.625 V threshold for compatibility with target logic levels. Evaluate the TO-92-3 package suitability for through-hole assembly constraints and operating temperature requirements.

Supervisors Part Context

This part belongs to the DS1833 series of supervisory circuits manufactured by Analog Devices / Maxim Integrated. It is categorized under PMIC - Power Management ICs, specifically within the Supervisory Circuits subcategory. The series focuses on providing essential voltage monitoring solutions for various electronic applications.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1833 family that match the specific voltage threshold and output type. Verify pin compatibility and package dimensions if replacing with components from other manufacturers.
