DS1232LPSN

Supervisors Overview

The DS1232LPSN+ 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 features a reset delay time of 610 ms. The device monitors a single input with an overvoltage threshold of 4.74 V and offers active high, active low, or open drain output types. It includes a watchdog timer but lacks manual reset and battery backup switching capabilities. Operating temperatures span from -40°C to +85°C, with a typical quiescent current of 200 µA.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides configurable reset outputs including active high, active low, and open drain options
• Detects power failures without requiring manual reset inputs
• Designed for low-power operation in microprocessor systems

Supervisors Applications

• Microprocessor power supervision
• Watchdog timer implementation in embedded systems
• Voltage monitoring for portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix (+) indicates RoHS compliance when sourcing. Confirm package type matches SOIC-16 specifications. Check manufacturer documentation for lead times as availability may vary. Ensure operating temperature range meets application requirements. Validate pinout compatibility during integration.

Supervisors Selection Notes

Select this component for applications requiring integrated watchdog functionality alongside voltage supervision. Consider the 610 ms reset delay for timing constraints. Evaluate the 200 µA current consumption against power budgets. Verify that the absence of manual reset fits the design strategy. Compare against variants with different packages if space is limited.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for simple yet effective power management in digital circuits. It consolidates multiple supervisory functions into a single chip, reducing component count. The series is known for reliability in industrial and consumer electronics environments.

Supervisors Replacement Considerations
