DS1232SN+T&R

Supervisors Overview

The DS1232SN+T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 4.5 V to 5.5 V and features a reset delay time of 1 s. The device provides power-fail detection with an overvoltage threshold of 4.74 V and maintains an accuracy of 10%. It includes an integrated watchdog timer and supports multiple output types, including active high, active low, open drain, and push-pull configurations. Designed for surface-mount installation in SOIC-Wide-16 packages, it functions reliably across a temperature range of -40°C to +85°C with a typical operating current of 2 mA.

Supervisors Feature Summary

• Integrates a watchdog timer for microprocessor system protection against software malfunctions
• Provides comprehensive power management through power-fail detection and voltage monitoring
• Offers flexible output drive capabilities with selectable active high, active low, open drain, or push-pull modes

Supervisors Applications

• Microprocessor system supervision
• Embedded controller reset generation
• Industrial control system reliability enhancement

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity upon receipt as the unit utilizes reel packaging. Ensure compatibility with existing design specifications regarding voltage thresholds and thermal requirements before implementation. Cross-reference datasheet revisions to confirm pinout consistency with current manufacturing standards.

Supervisors Selection Notes

Select this component when a dedicated supervisory circuit with integrated watchdog functionality is required for 5V logic systems. The SOIC-Wide-16 package suits applications needing robust surface-mount integration. Consider the specific output configuration needs, as the device supports various drive styles. Verify that the 1-second reset delay aligns with system startup timing requirements.

Supervisors Part Context
