DS1232LPSN/T&R

Supervisors Overview

The DS1232LPSN/T&R is a low-power MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum operating voltage of 5.5 V and a typical quiescent current of 200 µA. The device monitors a single input channel and provides active high, active low, and open drain outputs. It features a watchdog timer and power-fail detection but lacks manual reset and battery backup switching capabilities. The reset delay time is specified at 610 ms, with an accuracy of 10%. The component is housed in a SOIC-Wide-16 package and supports surface-mount installation.

Supervisors Feature Summary

• Integrates watchdog timer functionality for microprocessor system monitoring
• Provides multiple output configurations including active high, active low, and open drain
• Detects power failures to ensure system integrity during voltage fluctuations

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded systems
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the required package type and temperature range. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit with integrated watchdog functionality is required for single-channel voltage monitoring. Consider the SOIC-Wide-16 package constraints and the absence of manual reset or battery backup features. Evaluate the 610 ms reset delay and 10% accuracy against system timing requirements. Verify that the 200 µA quiescent current aligns with power budget limitations.
