DS1231S-20+

Supervisors Overview

The DS1231S-20+ is a supervisory power monitor circuit manufactured by Analog Devices Inc./Maxim Integrated. It is housed in a 16-SOIC package and designed to monitor system voltage levels for proper operation. The device features an open-drain or open-collector output configuration, providing a single channel of supervision. It operates within a specified temperature range suitable for commercial applications.

Supervisors Feature Summary

• Provides continuous monitoring of power supply voltage levels to ensure system integrity
• Features an open-drain or open-collector output interface for flexible logic compatibility
• Designed as a dedicated supervisory circuit for reliable power management

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller-based designs needing power reset signals
• Industrial control equipment with strict power monitoring requirements

Supervisors Procurement Notes

Verify the exact suffix and manufacturer designation when sourcing, as listings may vary between Maxim Integrated and Analog Devices branding. Confirm the package type is 16-SOIC and check RoHS compliance status via official datasheets. Ensure the specific variant matches the required voltage threshold and output configuration for your design.

Supervisors Selection Notes

Select this component when a simple, single-channel voltage supervisor is needed for commercial temperature ranges. Consider the open-drain output capability if interfacing with various logic families. Verify that the operating voltage range aligns with your system's power rails before integration into the schematic.

Supervisors Part Context

This part belongs to the DS1231 series of power monitors from Maxim Integrated, now part of Analog Devices. These devices are commonly used in legacy and current designs requiring basic power supervision without complex configuration. The series includes variants with different voltage thresholds and timing characteristics.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as other DS1231 variants with adjusted thresholds. Cross-reference with similar open-drain supervisors from Analog Devices or Maxim to ensure functional equivalence in voltage monitoring and output drive capabilities.
