DS1232SN/T&R

Supervisors Overview

The DS1232SN/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed to ensure system stability during power anomalies. It operates within a supply voltage range of 4.5 V to 5.5 V and features a reset delay time of 1 second. The device includes an integrated watchdog timer and detects power failures with an overvoltage threshold of 4.74 V. It provides multiple output types including active high, active low, open drain, and push-pull configurations. The component supports 10% accuracy and functions at a working supply current of 2 mA across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for program execution monitoring and automatic reset upon timeout.
• Detects power failures and generates reset signals to protect microprocessor systems.
• Offers flexible output configurations including active high, active low, open drain, and push-pull modes.

Supervisors Applications

• Microprocessor system supervision in embedded controllers
• Industrial control equipment requiring stable power monitoring
• Communication devices needing watchdog protection

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation as requirements may vary by production batch. Ensure the SOIC-Wide-16 package dimensions match your PCB footprint design constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a supervisory circuit with both voltage monitoring and watchdog functionality is required. The 1-second reset delay suits applications needing extended stabilization periods. Verify that the 2 mA operating current aligns with system power budgets compared to lower-power alternatives like the DS1232LP series if battery life is critical.

Supervisors Part Context

This part belongs to the DS1232 family of MicroMonitor chips originally developed by Dallas Semiconductor and later acquired by Maxim Integrated, now part of Analog Devices. These circuits are widely used to enhance hardware reliability in digital systems by managing reset conditions and preventing software lockups through hardware-level intervention.

Supervisors Replacement Considerations

DS1232SN+ is a direct pin-compatible alternative without tape-and-reel packaging. DS1232LP+ offers lower static current but lacks the watchdog feature and uses an 8-pin DIP package instead of 16-pin SOIC.
