DS1833Z-10+T&R

Supervisors Overview

The DS1833Z-10+T&R is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 5.5V and features a fixed threshold voltage of 4.375V with a 10% tolerance. The device provides an active high reset output via a push-pull, totem pole configuration. It includes a minimum reset timeout period of 250ms to ensure stable power-up sequencing. The component is designed for surface mount installation in SOT-223 packages and supports manual reset functionality. It operates reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single voltage input to detect power supply anomalies
• Provides an active high reset signal with push-pull output capability
• Includes a defined reset timeout period for reliable system initialization

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered systems requiring voltage supervision
• Industrial control equipment power management

Supervisors Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as T&R indicate tape and reel packaging while other suffixes may denote tube packaging or RoHS compliance status. Confirm the specific threshold voltage accuracy and package type required for your design, as these parameters are critical for compatibility. Ensure that the active high output logic aligns with the receiving component's input requirements before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when an active high reset signal is required for the target system architecture. The 4.375V threshold makes it suitable for 5V logic systems or battery applications where voltage levels drop below nominal operating ranges. Consider the push-pull output drive strength if connecting directly to sensitive inputs without external pull-up resistors. Verify that the 250ms timeout meets the startup time requirements of the monitored processor or memory devices.

Supervisors Part Context

This part belongs to the DS1833 series of simple reset circuits designed for cost-sensitive applications. It serves as a fundamental power management component in mixed-signal designs. The series offers various threshold voltages to accommodate different supply rails. The DS1833Z variant specifically denotes the lead-free and RoHS-compliant version of the standard DS1833 supervisor, ensuring environmental compliance for modern manufacturing processes.

Supervisors Replacement Considerations

Direct replacements include the DS1833Z-10 (tube packaging) or DS1833Z-10/T&R (tape and reel). Other variants in the DS1833 family with compatible thresholds may be used if pinout and electrical characteristics match. Verify that any substitute maintains the active high output polarity and similar reset timeout specifications.
