DS1833-15+T&R

Supervisors Overview

The DS1833-15+T&R is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, belonging to the EconoReset series. It functions as a simple reset generator with a single monitored voltage channel and a threshold of 4.625V. The device provides an active-high push-pull output and features a minimum reset timeout of 250ms. Designed for through-hole mounting in TO-92-3 packages, it operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Generates system reset signals upon power-up or voltage drop below threshold
• Provides active-high push-pull output for direct logic interfacing
• Includes manual reset capability via external pushbutton input

Supervisors Applications

• Microcontroller power-on reset circuits
• Battery-powered system supervision
• Embedded device voltage monitoring

Supervisors Procurement Notes

Verify package type compatibility during sourcing, as this component utilizes a through-hole TO-92-3 configuration rather than surface-mount variants. Confirm RoHS compliance status with the manufacturer, as historical data indicates potential non-compliance for specific manufacturing batches. Ensure the active-high output polarity matches the target microcontroller's reset pin requirements before integration into the design.

Supervisors Selection Notes

Select this component when a through-hole solution is required for low-cost voltage supervision. The fixed 4.625V threshold suits standard 5V logic systems. Consider alternative surface-mount versions if PCB space constraints preclude the use of TO-92-3 packages. Verify that the 250ms minimum delay meets the startup timing requirements of the connected processor.

Supervisors Part Context

This part belongs to the DS1833 family of supervisory circuits designed for cost-sensitive applications. It serves as a fundamental power management component for ensuring stable operation of digital systems by detecting under-voltage conditions. The EconoReset series emphasizes simplicity and reliability without complex programmability.
