DS1232LPS-2

Supervisors Overview

The DS1232LPS-2+ is a low-power MicroMonitor chip manufactured by Analog Devices / 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 one input and provides active high, active low, and open drain outputs. It includes a watchdog timer but lacks manual reset and battery backup switching capabilities. Operating temperatures range from 0°C to +70°C with an accuracy of 10%. The quiescent current is 200 µA, and it is housed in an SOIC-8 package.

Supervisors Feature Summary

• Integrates super-low power operation with a watchdog timer for microprocessor control
• Automatically restarts the microprocessor following power failure events
• Monitors pushbutton inputs for external override functionality

Supervisors Applications

• Microprocessor system supervision
• Power failure monitoring circuits
• Watchdog timer implementations

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status through manufacturer documentation. Ensure the SOIC-8 package matches the target PCB footprint requirements before procurement.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. Consider the 200 µA quiescent current for low-power designs. Verify that the 610 ms reset delay meets system timing constraints. Ensure the operating temperature range aligns with the application environment.

Supervisors Part Context

This part belongs to the DS1232LPS series of low-power supervisory circuits. It serves as a specialized voltage monitor designed to ensure system reliability by detecting power anomalies and managing processor resets without requiring external components for basic supervision functions.

Supervisors Replacement Considerations

Consult official substitution lists for compatible parts within the same family or equivalent supervisory circuits with matching package and electrical specifications.
