DS1236-5

Supervisors Overview

The DS1236-5 is a MicroManager supervisory circuit designed for microprocessor applications. It monitors a single voltage rail with an accurate 5% power supply monitoring threshold. The device features open-drain and push-pull outputs, providing active high and active low reset signals. It includes a watchdog timer and manual reset capability to halt or restart out-of-control processors. The component operates within a temperature range of 0°C to +70°C and is available in 16-pin DIP or SOIC packages.

Supervisors Feature Summary

• Holds microprocessor in check during power transients
• Monitors pushbutton for external override
• Converts CMOS SRAM into nonvolatile memory
• Provides orderly shutdown in nonvolatile microprocessor applications

Supervisors Applications

• Nonvolatile microprocessor applications requiring orderly shutdown
• Battery operated hand-held applications needing low-power stop mode control
• High current applications controlled by external power switches

Supervisors Procurement Notes

Verify the specific suffix (e.g., A, AS) against the required package type and temperature rating. Confirm availability status as some variants may be discontinued or restricted. Ensure the selected part matches the exact voltage threshold requirements for the target system design.

Supervisors Selection Notes

Select this variant when precise 5% voltage monitoring is required rather than the standard 10%. Consider the package style based on board space constraints. Verify that the operating temperature range meets the environmental conditions of the intended application before finalizing the component choice.

Supervisors Part Context

This component belongs to the DS1236 MicroManager family, which integrates supervisory functions into a single chip. It combines voltage monitoring, reset generation, and battery backup switching capabilities. The series is designed to protect microprocessors from power-related failures and ensure data integrity during unexpected power loss events.

Supervisors Replacement Considerations

DS1236S-10+T&R; offers similar functionality but with a different monitoring accuracy.
