DS1233MS-3/T&R

Supervisors Overview

The DS1233MS-3/T&R is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors a single input with a threshold voltage of 2.72V and an overvoltage threshold of 4.75V. The device features active low, open drain output and provides a reset delay time of 350 ms. It operates within a supply voltage range up to 5.5V and maintains accuracy of 5%. The component supports surface mount installation in an 8-SOIC package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides power-fail detection for system protection
• Features manual reset capability for user control
• Includes integrated watchdog timer functionality

Supervisors Applications

• Microprocessor (MPU) monitoring systems
• Voltage supervision in embedded controllers
• Power management circuits requiring reset signals

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging configuration when sourcing. Confirm the manufacturer designation matches Analog Devices or Maxim Integrated as the current entity. Ensure the part number aligns with the 8-SOIC package variant rather than other pinouts. Cross-reference the threshold voltage specifications against the latest datasheet to confirm compatibility with target supply rails.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset and watchdog features is required. The 8-SOIC package suits surface-mount designs needing compact footprints. Verify that the 2.72V threshold aligns with the monitored rail's nominal voltage. Consider the operating temperature range if deployed in industrial environments.

Supervisors Part Context

This part belongs to the DS1233 family of supervisory circuits designed for cost-effective power management. It integrates essential functions like reset generation and watchdog timing into a small form factor. The series is commonly used in consumer electronics and industrial equipment where reliable power sequencing is critical.

Supervisors Replacement Considerations

Check for direct equivalents within the DS1233 series such as DS1233MS-3+ variants. Verify pinout compatibility before substituting with other SOIC supervisors. Ensure functional equivalence regarding watchdog timeout periods and reset delay times.
