DS1233AZ-15/T&R

Supervisors Overview

The DS1233AZ-15/T&R is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a reset threshold of 4.125V with an overvoltage threshold of 2.8V. The device provides a reset delay time of 350ms and consumes a typical operating supply current of 50uA. It offers power-fail detection capabilities without manual reset or watchdog timer functions. The component is available in surface-mount SOT-223-3 packaging and supports active low, open drain, or push-pull output configurations.

Supervisors Feature Summary

• Provides voltage supervision with power-fail detection for system integrity
• Features configurable reset thresholds and flexible output drive options
• Designed for low-power applications with minimal operating current consumption

Supervisors Applications

• Embedded systems requiring reliable power monitoring
• Microcontroller-based designs needing automatic reset on voltage anomalies
• Portable electronics utilizing battery backup scenarios

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and electrical characteristics. Ensure compatibility with target voltage rails and thermal requirements. Cross-reference manufacturer part numbers to avoid confusion between similar variants in the EconoReset family. Confirm RoHS compliance status if required for regulatory adherence.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated power-fail detection is required. Consider the 350ms reset delay and 50uA current draw for low-power constraints. Evaluate the SOT-223-3 footprint against board space limitations. Compare threshold accuracy and overvoltage protection levels against alternative supervisors in the same series.

Supervisors Part Context

This part belongs to the DS1233Z/A EconoReset family, which integrates voltage monitoring and power-fail signaling into a compact solution. The series is designed to simplify system design by combining essential supervisory functions without external components. Variants differ primarily in threshold voltages, packages, and manufacturing revisions.

Supervisors Replacement Considerations

DS1233Z-15+ and DS1233A-10+ are related family members but differ in package and threshold specifications. Verify pinout compatibility and electrical parameters before substitution. No direct public substitute part numbers are confirmed for this exact variant.
