DS1233D-15/T&R

Supervisors Overview

The DS1233D-15/T&R is a single-channel voltage supervisor from the EconoReset series by Analog Devices Inc./Maxim Integrated. It features an open-drain or open-collector output with active-low reset assertion and a minimum reset timeout of 250ms. The device monitors one input voltage against a threshold of 4.125V. It operates within a temperature range of -40°C to 85°C and is housed in a SOT-223-3 surface-mount package.

Supervisors Feature Summary

• Provides simple power-on reset functionality for microprocessor systems
• Features open-drain or open-collector output configuration
• Includes manual reset capability for system control

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered equipment supervision
• Portable electronic device protection

Supervisors Procurement Notes

Verify the exact suffix designation, as datasheets typically list variants like DS1233DZ-15+T&R. Confirm the specific package type (SOT-223 vs TO-261) matches the design requirements. Ensure the manufacturer source is recognized as Analog Devices or Maxim Integrated for authenticity. Check RoHS compliance status if required by project specifications.

Supervisors Selection Notes

Select this component when a fixed 4.125V threshold is appropriate for the target rail. The SOT-223-3 package suits space-constrained surface-mount designs. Consider the 250ms minimum timeout duration relative to the system's startup sequence requirements. Verify that the open-drain output interface aligns with the connected logic levels.

Supervisors Part Context

This part belongs to the DS1233 family of supervisory circuits designed for cost-sensitive applications. It serves as a fundamental building block for ensuring reliable system initialization and fault detection in embedded electronics managed by Analog Devices' portfolio.

Supervisors Replacement Considerations

Cross-reference with DS1233A-15+T&R for similar functionality in different packages. Verify pinout compatibility before substituting with other EconoReset series components.
