DS1232LP+

Supervisors Overview

The DS1232LP+ 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 typical reset delay time of 610 ms with an accuracy of 10%. The device monitors a single input and provides active high, active low, or open drain outputs. It includes a watchdog timer but lacks manual reset and battery backup switching capabilities. Designed for through-hole installation in an 8-pin PDIP package, it functions within a temperature range of 0°C to +70°C while consuming 200 µA of operating current.

Supervisors Feature Summary

• Integrates power supply monitoring with automatic reset generation upon detecting under-voltage conditions
• Includes a built-in watchdog timer to detect software malfunctions and trigger system recovery
• Offers configurable output drivers supporting active high, active low, and open drain logic states

Supervisors Applications

• Microprocessor system supervision for ensuring stable operation during power fluctuations
• Embedded systems requiring automated recovery from brown-out events without manual intervention
• Industrial control circuits utilizing through-hole mounting for robust mechanical stability

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as variations exist between standard and lead-free (plus) versions. Confirm that the required threshold voltage aligns with the fixed internal settings of the LP variant. Ensure the application environment remains within the specified commercial temperature limits. Check for availability constraints as distribution status may vary by region. Validate package compatibility with existing PCB footprints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a low-power solution is required for single-supervision applications without manual reset needs. The fixed threshold characteristics suit designs where precise external resistor networks are undesirable. Consider the PDIP package for prototyping or applications requiring through-hole assembly techniques. Evaluate if the absence of battery backup switching meets the system's continuity requirements during power loss scenarios.

Supervisors Part Context

This part belongs to the DS1232LP series of MicroMonitor™ chips originally developed by Dallas Semiconductor and later acquired by Maxim Integrated, now part of Analog Devices. The series focuses on providing essential supervisory functions with minimal quiescent current consumption. The LP designation typically indicates a low-power variant optimized for efficiency compared to earlier generations in the family.
