DS1232LPN

Supervisors Overview

The DS1232LPN 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 includes an integrated watchdog timer and power-fail detection capabilities without battery backup switching. It provides active high, active low, or open drain output types and lacks manual reset functionality. The component is housed in an 8-pin PDIP package with through-hole mounting and supports a working supply current of 200 uA.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides configurable reset output states including active high, active low, and open drain
• Detects power failures to ensure controlled system shutdown or restart

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset management
• Industrial control unit monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the selected variant matches the required operating temperature range and package type for the target application design.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with watchdog functionality is required. Consider the 610 ms reset delay and 200 uA quiescent current for low-power designs. Verify compatibility with the system's logic levels given the multiple output drive options available in this series.

Supervisors Part Context

This part belongs to the DS1232LP MicroMonitor series, designed for microprocessor applications requiring comprehensive power management supervision. It combines voltage monitoring, watchdog timing, and power-fail signaling into a single low-cost IC, simplifying board layout compared to discrete solutions.

Supervisors Replacement Considerations

DS1232LP+ serves as a direct replacement within the same product family.
