DS1233DZ-10+T&R

Supervisors Overview

The DS1233DZ-10+T&R is a single-channel voltage supervisor IC from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage with a threshold of 4.375V and an overvoltage threshold of 2.97V. The device features an active low, open drain output and provides a reset delay time of 350 ms. It operates within a supply voltage range of 1.2 V to 3.3 V, with a maximum rating of 5.5 V in some contexts, and consumes 50 uA of operating current. The component supports power fail detection and is housed in a SOT-223-3 package for surface mount installation.

Supervisors Feature Summary

• Provides simple reset and power-fail detection for single-voltage monitoring applications
• Features an active low open-drain output compatible with various logic families
• Includes a minimum reset timeout period to ensure stable system initialization

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Power management circuits requiring voltage monitoring
• Embedded systems needing reliable reset generation during power transitions

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when ordering. Confirm the exact voltage threshold requirements match the 4.375V specification for your application. Ensure compatibility with the SOT-223-3 surface mount footprint during PCB layout. Check for RoHS compliance status if required by your manufacturing standards. Validate that the operating temperature range meets your environmental conditions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with an open-drain output is required. Consider the 4.375V threshold for systems operating near this voltage level. The SOT-223-3 package offers a compact solution for space-constrained designs. Evaluate the 350 ms reset delay against your system's startup timing requirements. Ensure the 50 uA quiescent current fits your power budget constraints.

Supervisors Part Context

This part belongs to the DS1233A/D series of EconoReset supervisors, designed for cost-sensitive applications. It simplifies circuit design by integrating power-fail detection and reset generation into a single small package. The series is widely used in consumer electronics and industrial control systems where basic voltage monitoring is sufficient without complex watchdog or battery backup features.

Supervisors Replacement Considerations

Direct substitutes include other DS1233 variants with different voltage thresholds such as DS1233-5+ or DS1233DZ-10+. Cross-reference with similar single-channel supervisors from Analog Devices or Maxim Integrated offering comparable reset delays and output types. Verify pinout compatibility before replacing to ensure seamless integration without PCB modifications.
