DS1236N-5+

Supervisors Overview

The DS1236N-5+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V and monitors a single input channel. The device features active high and active low outputs, manual reset capability, and an integrated watchdog timer with battery backup switch functionality. It provides a reset delay time of 150 ms and includes power failure detection. The component is housed in a 16-SOIC wide package for surface mount installation and supports chip enable signals.

Supervisors Feature Summary

• Integrates watchdog timer and battery backup switch for comprehensive system protection
• Provides both active high and active low output options for flexible logic interfacing
• Includes manual reset input for direct user control over system state

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller-based designs needing watchdog protection
• Industrial equipment with battery backup requirements

Supervisors Procurement Notes

Verify the specific suffix 'N' against official datasheets to confirm package type and temperature rating. Confirm RoHS compliance status as '+'. Check current lifecycle status as discontinued or limited availability may affect long-term sourcing. Ensure pinout compatibility with existing PCB layouts before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with watchdog and battery backup is required. Verify that the 4.5 V to 5.5 V operating range matches the system supply. Consider the 16-SOIC package size for board space constraints. Compare threshold voltages if precise monitoring levels are critical for the application.

Supervisors Part Context

This part belongs to the DS1236 series of MicroManager supervisory circuits. It is designed for applications requiring reliable power management and system reset functions. The series typically integrates multiple protection features into a single compact package, simplifying design for embedded systems.

Supervisors Replacement Considerations

Check for DS1236S-5+ or DS1236AS-5+ as potential alternatives within the same family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
