DS1238A-5+

Supervisors Overview

The DS1238A-5+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V with a threshold voltage of 5 V. The device monitors one input and features active high, active low, open drain, and push-pull outputs. Key specifications include a reset delay time of 150 ms, a watchdog timer, manual reset capability, and battery backup switching. It consumes 4 mA during operation and detects power failures. The component is housed in a PDIP-Narrow-16 package for through-hole installation and functions between 0°C and +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes manual reset functionality for user-initiated control
• Supports battery backup switching for continuous operation during power loss
• Provides multiple output types including active high, active low, open drain, and push-pull

Supervisors Applications

• Voltage supervision in embedded systems
• Power failure detection circuits
• Watchdog timer implementation in microcontroller designs
• Battery backup management in portable electronics

Supervisors Procurement Notes

Verify the exact suffix designation as official documentation lists the part number as DS1238A-5 without the plus sign. Confirm availability status as the product lifecycle is marked as obsolete or discontinued. Ensure the PDIP-Narrow-16 through-hole package matches the design requirements. Check for RoHS compliance details if required by specific manufacturing standards.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with integrated watchdog and manual reset is required. The 5 V threshold suits standard 5 V logic systems. Consider the PDIP-Narrow-16 package for through-hole assembly needs. Verify that the 150 ms reset delay and 4 mA operating current align with system power and timing constraints.

Supervisors Part Context

The DS1238A series belongs to the Voltage Supervisory Circuits category under PMIC - Power Management ICs. It is part of the Analog Devices / Maxim Integrated portfolio. The device combines power management supervision with system protection features like watchdog timers and battery backup switching in a single integrated circuit solution.
