DS1232S+T&R

Supervisors Overview

The DS1232S+T&R is a MicroMonitor Chip supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75 V to 5.5 V and features a threshold voltage between 4.5 V and 5.5 V. The device includes a watchdog timer, power-fail detection, and a reset delay time of 1 second. It has an accuracy of 10% and a typical operating supply current of 2 mA. The component supports active high, active low, open drain, and push-pull output types. It is housed in a SOIC-Wide-16 package for surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Provides power-fail detection capabilities
• Supports multiple output configurations including open drain and push-pull

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microprocessor reset circuits
• Industrial control equipment monitoring

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation as availability varies. Check for obsolescence notices from Analog Devices or Maxim Integrated prior to finalizing procurement plans. Ensure the SOIC-Wide-16 package dimensions match your PCB layout requirements.

Supervisors Selection Notes

Select this component when a supervisory circuit with integrated watchdog functionality is required. Consider the 1-second reset delay and 10% accuracy specifications against system timing constraints. Evaluate the 2 mA operating current against power budget limitations. Verify compatibility with the target microprocessor's reset input requirements regarding active levels and drive capability.

Supervisors Part Context

This part belongs to the DS1232SN series of supervisory circuits from Analog Devices/Maxim Integrated. These devices are designed to monitor voltage levels and provide reliable reset signals for digital systems. The series typically includes variations in package types and specific threshold voltages to suit different application needs.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the DS1232 family. Verify that alternative parts maintain the same watchdog and power-fail features. Ensure the replacement supports the required SOIC-Wide-16 package if space is constrained.
