DS1233MS-55+

Supervisors Overview

The DS1233MS-55+ is a voltage supervisory circuit from the EconoReset series by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 4.625 V with an overvoltage threshold of 4.75 V. The device provides a reset delay time of 350 ms and maintains an accuracy of 2.5%. It draws a working power supply current of 50 uA. The output type is Active Low, Open Drain, Push-Pull. It supports power failure detection but lacks manual reset, watchdog timer, or battery backup switching functions. The component is housed in an SOIC-8 package and operates between -40 C and +85 C.

Supervisors Feature Summary

• Provides voltage supervision with active low open drain and push-pull output capabilities
• Includes power failure detection functionality for system integrity monitoring
• Operates with low quiescent current consumption suitable for energy-efficient designs

Supervisors Applications

• Embedded systems requiring reliable power management
• Microcontroller-based circuits needing supervised reset signals
• Industrial control equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix and packaging configuration against official datasheets before procurement. Confirm availability status as distribution channels may indicate limited stock. Ensure the ordering part number matches the required tolerance and package variant. Cross-reference manufacturer documentation to validate functional specifications for your specific application requirements.

Supervisors Selection Notes

Select this component when a precise 4.625 V threshold is required for 5 V systems. Consider the SOIC-8 surface mount package for PCB space constraints. Evaluate the 2.5% accuracy specification against system tolerance needs. Verify that the absence of a watchdog timer aligns with the overall system architecture design.

Supervisors Part Context

This component belongs to the DS1233M family of voltage supervisors designed for simple reset generation. It serves as a cost-effective solution for monitoring single input voltages without complex interface requirements. The EconoReset series emphasizes low power consumption and basic supervisory functions for standard digital logic applications.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer portfolio. Verify that substitute parts maintain identical threshold voltages and output drive characteristics. Ensure replacement components support the same operating temperature range and package dimensions.
