DS1233MS-55+T&R

Supervisors Overview

The DS1233MS-55+T&R is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./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 accuracy of 2.5%. The device provides power failure detection and utilizes an active low, open drain output type. It includes a reset delay time of 350 ms and consumes a working supply current of 50 uA. The component supports overvoltage detection at 4.75 V and functions across a temperature range of -40°C to +85°C. It is housed in an SOIC-8 package and supplied in a reel format.

Supervisors Feature Summary

• Provides power failure detection capability for system monitoring
• Features active low open drain output configuration
• Includes manual reset functionality absence and watchdog timer absence

Supervisors Applications

• Voltage supervision in embedded systems
• Power management circuits requiring reset signals
• Electronic devices operating within specified temperature ranges

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm the manufacturer part number matches DS1233MS-55+. Check availability status as distribution may be limited. Ensure compatibility with existing PCB footprints for SOIC-8 packages. Validate RoHS compliance requirements against project specifications before procurement.

Supervisors Selection Notes

Select this component for applications requiring precise voltage monitoring with low standby current consumption. The 2.5% accuracy ensures reliable threshold detection. Consider the SOIC-8 package for surface mount assembly needs. Evaluate the 350 ms reset delay against system startup timing requirements. Verify that the open drain output suits the downstream logic interface design constraints.

Supervisors Part Context

This part belongs to the DS1233M family of supervisory circuits designed for cost-effective power management solutions. It complements other variants like the DS1233Z-5+ and DS1233MS-5+T&R by offering specific threshold and package options. The series focuses on providing essential reset functions without complex features like watchdog timers or battery backup switches.

Supervisors Replacement Considerations
