DS1231-20N+

Supervisors Overview

The DS1231-20N+ is a supervisory circuit power monitor manufactured by Analog Devices Inc. (formerly Maxim Integrated). It is housed in an 8-pin PDIP package and functions as a fixed power supply support circuit with one channel. The device monitors voltage levels within the +4.37V to +4.62V range, utilizing CMOS technology for signal processing. Designed for surface or through-hole mounting, it ensures system reliability by detecting power anomalies.

Supervisors Feature Summary

• Provides fixed threshold monitoring for power supply integrity
• Features open-drain or open-collector output configuration
• Ensures reliable operation across specified industrial temperature ranges

Supervisors Applications

• Embedded systems requiring precise power supervision
• Industrial control units needing voltage anomaly detection
• Communication equipment power management circuits

Supervisors Procurement Notes

Verify the manufacturer designation, as Analog Devices acquired Maxim Integrated. Confirm the package type matches the 'N' suffix requirement. Ensure the specific revision level meets project specifications. Cross-reference datasheets for pinout consistency between legacy Maxim and current ADI documentation.

Supervisors Selection Notes

Select this component when a fixed voltage threshold near 4.5V is required. Compare against other DS123x variants for different reset delays or thresholds. Consider package availability if PCB layout constraints exist. Verify compatibility with system logic levels for the open-drain output interface.

Supervisors Part Context

Part of the DS123x family of power supply supervisors. This series provides essential protection for microprocessors and memory devices. The DS1231 variant specifically targets applications requiring a fixed monitoring window without adjustable thresholds.
