DS1232LPSN-2/T&R

Supervisors Overview

The DS1232LPSN-2/T&R is a low-power MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.3 V to 5.5 V and monitors a single input channel. The device features an active high, active low, or open drain output type with a reset delay time of 610 ms. It includes a watchdog timer but lacks manual reset and battery backup switching capabilities. The component is housed in an SOIC-Narrow-8 package and supports surface mount installation. It functions as a voltage monitor with power failure detection and maintains an accuracy of 10% across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring without requiring external components.
• Provides configurable output states including active high, active low, and open drain options.
• Detects power failures to ensure reliable operation during voltage fluctuations.

Supervisors Applications

• Embedded systems requiring automated reset sequences upon power loss.
• Industrial control units needing watchdog functionality for fault recovery.
• Portable electronic devices utilizing low-power supervisory monitoring.

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical characteristics, as variations exist within the family. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure the SOIC-Narrow-8 package dimensions match your PCB footprint requirements. Cross-reference the part number with authorized distributors to validate authenticity and current availability status.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog timing is required. Consider the 610 ms reset delay and 10% accuracy specifications for timing-sensitive applications. Evaluate the -40°C to +85°C industrial temperature range suitability for your operational environment. Compare against other MicroMonitor variants if manual reset or battery backup switching features are necessary for the design.

Supervisors Part Context

This part belongs to the DS1232LPSN series of low-power supervisory circuits from Maxim Integrated. It is designed to provide robust power management solutions for microprocessor-based systems. The series emphasizes low quiescent current and compact packaging to support space-constrained designs.
