DS1232S/T&R

Supervisors Overview

The DS1232S/T&R is a MicroMonitor 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 monitors one input and provides active high, active low, open drain, or push-pull outputs. It includes a watchdog timer and power-fail detection capabilities. The reset delay time is 1 second with an accuracy of 10%. Operating temperatures range from -40°C to +85°C, and the package is SOIC-Wide-16.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Detects power failures to ensure data integrity during voltage drops
• Offers flexible output configurations including active high, active low, open drain, and push-pull

Supervisors Applications

• Embedded systems requiring automatic reset upon power loss
• Industrial control units needing watchdog supervision
• Portable devices operating on single-supply voltages

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against official distributor catalogs before ordering. Confirm RoHS compliance status as indicated in current manufacturer documentation. Ensure the SOIC-Wide-16 footprint matches your PCB design constraints. Check for any recent product change notices that may affect pinout or electrical characteristics.

Supervisors Selection Notes

Select this component when a combined power-fail detector and watchdog timer are required in a single IC. It is suitable for applications needing adjustable reset delays and multiple output drive types. Consider the wide operating temperature range for harsh environments. Verify that the supply voltage aligns with the 4.75 V to 5.5 V specification.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for simple reset and power-fail detection. It complements other supervisory circuits like the DS1233 series but adds integrated watchdog functionality. The device simplifies board design by reducing the component count needed for system protection and monitoring tasks.

Supervisors Replacement Considerations

DS1232SN+T&R is a documented substitute with identical functional specifications.
