DS1233AZ-15/TR/C17

Supervisors Overview

The DS1233AZ-15/TR/C17 is a voltage supervisory circuit from the EconoReset series by Analog Devices / Maxim Integrated. It monitors a single input with a threshold voltage of 4.125 V and an overvoltage threshold of 4.24 V. The device operates within a supply voltage range of 1.2 V to 5.5 V, drawing a typical quiescent current of 50 uA. It features a reset delay time of 350 ms and maintains an accuracy of 15%. Designed for surface mount applications, it is housed in an SOT-223-4 package and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides power-fail detection capabilities alongside standard voltage supervision.
• Features an active low output with open drain and push-pull configurations.
• Operates without requiring manual reset or chip enable signals.

Supervisors Applications

• Embedded system power monitoring
• Microcontroller reset generation
• Portable electronic device protection

Supervisors Procurement Notes

Verify the specific suffix TR/C17 against official datasheets to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly with the manufacturer or authorized distributors. Ensure the sourcing channel provides valid traceability for this Analog Devices component.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a 4.125 V threshold is required. The SOT-223-4 package suits space-constrained surface-mount designs. Consider the 15% accuracy and 350 ms delay for timing-sensitive applications. Verify that the 50 uA quiescent current meets low-power design constraints.

Supervisors Part Context

This part belongs to the DS1233Z family of EconoReset circuits. These devices are designed for simple, cost-effective voltage monitoring solutions. The series typically offers various threshold options and packages to accommodate different system requirements while maintaining consistent performance characteristics.

Supervisors Replacement Considerations

Check for DS1233Z-15+ as a potential tube-packaged alternative. Verify pinout compatibility and electrical specifications before substituting with other EconoReset variants.
