DS1236S-5+

Supervisors Overview

The DS1236S-5+ is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, belonging to the MicroManager series. It monitors a single input channel and provides active high and active low reset outputs in a 16-SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with an undervoltage threshold of 4.62 V. Key features include a manual reset input, a watchdog timer, and a battery backup switch. The reset delay time is specified at 25 ms minimum. It supports chip enable functionality and power failure detection, operating within a temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a battery backup switch for seamless power transition management
• Provides both active high and active low reset signal outputs
• Features a manual reset input for user-initiated system control

Supervisors Applications

• Voltage supervision in embedded systems requiring manual reset capability
• Power failure detection circuits in industrial equipment
• Battery backup switching applications in portable devices

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance and specific suffix variations against official datasheets. Check for lead-free certification if required by regulatory standards. Ensure packaging type matches design specifications. Validate lot traceability for critical applications.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog and manual reset is required. Consider the 16-SOIC package constraints and operating temperature range. Evaluate the need for active high/low outputs versus open-drain alternatives. Verify supply voltage compatibility with the 4.5 V to 5.5 V range. Assess if the 25 ms reset delay meets system timing requirements.

Supervisors Part Context

The DS1236S-5+ belongs to the Maxim Integrated MicroManager family of supervisory circuits. This series focuses on providing comprehensive power management solutions including voltage monitoring, watchdog timers, and battery backup switches. The DS1236 variant specifically targets applications requiring robust reset generation and manual intervention capabilities within standard voltage rails.

Supervisors Replacement Considerations

DS1236S-10N+T&R: Similar supervisory function but different reset delay and threshold characteristics. DS1236AS-5: Industrial temperature grade version with similar pinout and features. DS1236A-10+: Enhanced version with extended temperature range and updated specifications.
