DS1236A-10N+

Supervisors Overview

The DS1236A-10N+ is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 an overvoltage threshold of 4.5 V. The device provides active high and active low outputs, includes manual reset capability, and incorporates a watchdog timer and battery backup switch. It has a reset delay time of 150 ms and consumes 4 mA of operating current. The component is housed in a 16-SOIC-Wide package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates power-fail detection with active high and active low output signals for comprehensive voltage monitoring.
• Includes a built-in watchdog timer and battery backup switch to ensure system reliability during power anomalies.
• Supports manual reset functionality via a dedicated input pin for controlled system recovery.

Supervisors Applications

• Embedded systems requiring robust voltage supervision
• Industrial control units needing watchdog protection
• Data acquisition systems with battery backup requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm package integrity and pin alignment against the 16-SOIC-Wide specification. Review datasheet revisions for any functional updates. Ensure environmental compliance documentation matches project requirements. Validate thermal performance within the specified operating temperature range before integration.

Supervisors Selection Notes

Select this component when simultaneous overvoltage and undervoltage monitoring is required alongside watchdog functionality. The 150 ms reset delay suits applications tolerant of brief power interruptions. Consider the 4 mA quiescent current impact on overall system power budget. The SOIC-Wide package facilitates surface-mount assembly. Verify that the 4.5 V to 5.5 V operating range aligns with the target supply rail.

Supervisors Part Context

This part belongs to the DS1236 series of supervisory circuits designed for single-input voltage monitoring. It combines multiple protection features into a single integrated circuit, reducing board space compared to discrete solutions. The series is characterized by its inclusion of both standard reset generation and advanced features like watchdog timers and battery switches for critical applications.

Supervisors Replacement Considerations

DS1236S-10N+T&R serves as a tape-and-reel variant of the same functional core. DS1236A-10+ offers the same electrical specifications in a 16-PDIP through-hole package. Verify pin compatibility and package dimensions when substituting between SOP and DIP formats.
