DS1232N+

Supervisors Overview

The DS1232N+ is a MicroMonitor voltage supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides power supply monitoring with a threshold range of 3.3 V to 5.5 V and a maximum operating voltage of 5.5 V. The device features a reset delay time of 610 ms and an accuracy of 10%. It operates within a temperature range of -40°C to +85°C and consumes a working supply current of 500 uA. Packaged in an 8-pin PDIP through-hole format, it includes a watchdog timer and supports active high, active low, open drain, and push-pull output types.

Supervisors Feature Summary

• Integrates a watchdog timer for program execution monitoring
• Provides configurable reset delay times for stable power-up sequencing
• Supports multiple output drive configurations including open drain and push-pull

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as manufacturing sources may vary. Check current availability as this component may be subject to limited stock or obsolescence notices from distributors. Ensure the PDIP-8 package matches the target PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a through-hole solution with integrated watchdog functionality is required for industrial environments. The 10% accuracy and wide operating temperature range suit robust applications. Consider alternative packages if surface-mount technology is preferred. Verify that the manual reset input requirement aligns with the system design, as this specific variant lacks manual reset capability.

Supervisors Part Context

The DS1232 series belongs to the MicroMonitor family of supervisory circuits originally developed by Dallas Semiconductor and later acquired by Maxim Integrated, now part of Analog Devices. These devices are designed to monitor voltage levels and provide reset signals to microprocessors. The N+ suffix indicates a lead-free, RoHS-compliant version of the standard DS1232N package.
