DS1238S-5+

Supervisors Overview

The DS1238S-5+ is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 16-SOIC package. It monitors a single input channel with active high, active low, open drain, and push-pull outputs. The device features manual reset capability, a watchdog timer, and battery backup switching. Key electrical parameters include a threshold voltage of 5 V, a reset delay time of 150 ms, and an operating supply current of 4 mA. It supports power failure detection and chip enable signals, with overvoltage and undervoltage thresholds specified for system protection.

Supervisors Feature Summary

• Integrates voltage supervision, watchdog timer, and battery backup switching in a single component
• Provides multiple output configurations including active high, active low, open drain, and push-pull
• Supports manual reset functionality and chip enable signal control

Supervisors Applications

• Embedded systems requiring power failure detection
• Microcontroller reset circuits with watchdog capabilities
• Battery-backed memory or real-time clock applications

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm package type (16-SOIC) and temperature range specifications match design requirements. Check for obsolescence status as this part may be discontinued or limited in supply. Ensure compatibility with existing board layout and pinout before procurement.

Supervisors Selection Notes

Select this component when a combined supervisor, watchdog, and battery backup solution is required in a surface-mount package. Consider the 16-SOIC form factor for space-constrained designs. Evaluate the 150 ms reset delay and 4 mA operating current against system power budgets. Verify that the single-channel monitoring meets the specific voltage threshold needs of the target application.

Supervisors Part Context

The DS1238S-5+ belongs to the DS1238A series of supervisory circuits from Analog Devices/Maxim Integrated. This family provides integrated power management functions typically used in industrial and consumer electronics. The SOIC variant offers a surface-mount alternative to through-hole packages while maintaining similar functional characteristics within the product line.
