DS1233A-15/T&R

Supervisors Overview

The DS1233A-15/T&R is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2 V to 3.3 V and features a reset threshold of 2.88 V with an overvoltage threshold of 2.97 V. The device provides a minimum reset timeout of 250 ms and consumes a typical operating current of 50 uA. Packaged in TO-92-3 for through-hole mounting, it supports active low output configurations including open drain and push-pull modes. The component functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Monitors single input voltage against factory-set thresholds
• Provides power-fail detection with configurable output states
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Portable electronic device power monitoring

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as variants such as DS1233A-10+ and DS1233A-15+ differ in threshold voltages and accuracy specifications. Confirm package availability, noting that some distributors may list restricted supply status for tape-and-reel formats. Ensure compatibility with the target board's through-hole footprint requirements before finalizing procurement.

Supervisors Selection Notes

Select this component for applications requiring simple, low-cost voltage supervision without complex timing features. The fixed threshold eliminates external resistor network calibration needs. Consider the TO-92-3 package constraints for PCB layout. Evaluate the 250 ms minimum timeout against system startup requirements to ensure adequate reset duration during power-up sequences.

Supervisors Part Context

This part belongs to the DS1233A family of voltage supervisors designed for cost-sensitive applications. It simplifies power management by integrating threshold detection and reset generation into a compact three-pin package. The series offers various threshold options to match different logic families and supply rails.

Supervisors Replacement Considerations

Direct substitutes include other DS1233A variants with matching threshold voltages, such as DS1233A-10+ for 2.88 V threshold applications. Cross-reference pinout compatibility when replacing with similar TO-92-3 supervisors from other manufacturers.
