DS1233-5+T&R

Supervisors Overview

The DS1233-5+T&R is a voltage supervisory circuit manufactured by Analog Devices / Maxim Integrated, designed for monitoring power supply integrity. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.625 V with an accuracy of 5%. The device provides a reset delay time of 350 ms and includes power failure detection capabilities. It utilizes an active low, open drain, push-pull output type and lacks manual reset, watchdog timer, or battery backup switch functions. The component supports through-hole installation in a TO-92-3 package and maintains a typical operating supply current of 50 uA across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Integrates power failure detection for system reliability
• Provides active low open drain and push-pull output configurations
• Features fixed reset delay timing for consistent operation

Supervisors Applications

• Voltage supervision in embedded systems
• Power management in microcontroller circuits
• System reset generation for digital logic

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official documentation prior to integration. Ensure the TO-92-3 through-hole package aligns with PCB layout requirements. Cross-reference the manufacturer part number DS1233M-55+ or similar variants if alternative packages are required for the design.

Supervisors Selection Notes

Select this component for applications requiring a single-input voltage supervisor with moderate accuracy. The 5% threshold accuracy suits general-purpose digital systems rather than precision analog interfaces. Consider the TO-92-3 package constraints for space-limited designs. Evaluate the absence of a watchdog timer if complex fault recovery is necessary for the target application.

Supervisors Part Context

This part belongs to the DS1233 series of EconoReset supervisory circuits from Maxim Integrated. The series typically offers cost-effective solutions for basic power monitoring needs. Variants within the family differ primarily by package type, such as SOT-223 or SOIC-8, and threshold voltage specifications. The DS1233-5+T&R specifically denotes the through-hole version with reel packaging.
