DS1236S-10

Supervisors Overview

The DS1236S-10 is a MicroManager supervisory circuit designed for single-voltage monitoring applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features an undervoltage threshold of 4.25 V with a reset delay time of 150 ms. The device integrates a watchdog timer, manual reset input, and battery backup switch functionality. It is available in a 16-SOIC surface-mount package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Monitors power supply voltage to hold microprocessor in check during transients
• Converts CMOS SRAM into nonvolatile memory via battery backup switching
• Provides unconditionally write-protects memory when supply is out of tolerance

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 against official documentation, as variations exist between commercial and industrial temperature grades. Confirm availability status as this component may be discontinued or subject to limited supply constraints depending on the manufacturing lot and regional distributor allocation.

Supervisors Selection Notes

Select this part for systems requiring integrated voltage supervision, watchdog timing, and battery backup management in a single IC. Ensure the operating environment falls within the specified temperature range and that the supply voltage remains strictly within the 4.5 V to 5.5 V operational limits to maintain correct threshold detection.

Supervisors Part Context

This component belongs to the Maxim Integrated MicroManager family, which combines power supply monitoring with system control functions. These devices are engineered to manage complex power sequencing and protection tasks, replacing multiple discrete components typically used for reset generation and memory protection in embedded designs.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes such as the DS1236A-10+ or DS1236AS-10. Verify pin compatibility and electrical specifications before implementation.
