DS1236S-5

Supervisors Overview

The DS1236S-5 is a MicroManager supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed to monitor a single voltage channel. It operates within a commercial temperature range of 0°C to 70°C and utilizes a 16-SOIC surface-mount package with a width of 7.50mm. The device features an under-voltage threshold of 4.62V and provides both open-drain and push-pull output configurations. It supports active-high and active-low reset signals with a minimum timeout duration of 25ms. This component functions as a backup battery circuit to ensure system integrity during power fluctuations.

Supervisors Feature Summary

• Holds microprocessor in check during power transients
• Converts CMOS SRAM into nonvolatile memory
• Provides orderly shutdown in nonvolatile microprocessor applications

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'S' confirms the SOIC package variant rather than DIP. Confirm RoHS compliance status as some listings indicate non-compliance for this part number. Check manufacturer announcements regarding end-of-life or obsolescence status before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a 10% monitoring tolerance is required for a 5V supply rail. Ensure the design accommodates the 16-SOIC footprint and commercial temperature limits. Verify that the open-drain or push-pull output options meet the interface requirements of the target microprocessor.

Supervisors Part Context

This part belongs to the Maxim MicroManager family, which integrates power management and memory protection functions. The DS1236 series specifically targets applications where maintaining data integrity during power failures is critical, combining supervision with battery backup switching capabilities.

Supervisors Replacement Considerations

The DS1236S-10 serves as a functional substitute with identical packaging but a different voltage threshold.
