DS1236S-10+

Supervisors Overview

The DS1236S-10+ is a MicroManager supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input within a 4.5 V to 5.5 V range, featuring an under-voltage threshold of 4.25 V and an over-voltage threshold of 4.5 V. The device provides active high and active low outputs with a reset delay time of 150 ms. It includes manual reset capability, a watchdog timer, and battery backup switching functions. Operating from a supply voltage of 4.5 V to 5.5 V, it consumes 4 mA during operation and supports temperatures from -40°C to +85°C in a 16-SOIC package.

Supervisors Feature Summary

• 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 via external power switch

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm temperature range and monitoring accuracy. Confirm package type matches design requirements. Check for obsolescence status as this component may be discontinued. Ensure compatibility with existing system voltage thresholds before integration.

Supervisors Selection Notes

Select based on required voltage monitoring tolerance and operating temperature range. Verify output configuration needs for active high or low signals. Consider the need for integrated watchdog and battery backup features versus discrete solutions. Confirm package availability and lead times through authorized channels.
