DS1233AZ-10/T&R

Supervisors Overview

The DS1233AZ-10/T&R is a voltage supervisory circuit from the EconoReset series manufactured by Analog Devices / Maxim Integrated. It monitors a single input with a threshold voltage of 3.3 V and features an active low, open drain output. The device includes manual reset functionality but lacks a watchdog timer or battery backup switch. It operates within a supply voltage range of 1.2 V to 5.5 V and has a reset delay time of 450 ms. The component is designed for surface mount installation in SOT-223-3 packages and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides power-fail detection capabilities
• Includes manual reset control interface
• Features active low open drain output configuration

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as indicated in current datasheets. Ensure compatibility with required operating temperature ranges and supply voltage constraints before integration into final designs.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with manual reset capability is required. Verify that the 3.3 V threshold aligns with the monitored rail. Consider the SOT-223-3 package size for space-constrained PCB layouts. Ensure the open drain output suits the downstream logic requirements.

Supervisors Part Context

This part belongs to the DS1233A family of voltage supervisors. It is distinct from through-hole variants like the DS1233A-10+ which use TO-92-3 packages. The AZ suffix typically denotes specific manufacturing or packaging details within the Maxim Integrated portfolio. It serves as a fundamental power management IC for ensuring system stability during power transitions.
