DS1233MS-5/T&R

Supervisors Overview

The DS1233MS-5+T&R is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for power supply monitoring applications. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 4.375 V with an overvoltage detection threshold of 4.49 V. The device provides a reset delay time of 500 ms and consumes a typical operating current of 50 uA. It supports power-fail detection without manual reset or watchdog timer functionality. The component is housed in an SOIC-8 surface-mount package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Provides active low open-drain output for system reset signaling
• Includes dedicated power-fail detection capability
• Features factory-set threshold voltages for precise supervision

Supervisors Applications

• Microprocessor system reset generation
• Power supply voltage monitoring
• Embedded controller supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and electrical characteristics, as variations exist within the DS1233 series. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure availability constraints are addressed during procurement planning due to potential supply limitations associated with this specific reel packaging configuration.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 4.375 V is required for 5V logic systems. Consider the SOIC-8 package for surface-mount assembly requirements. Evaluate the 500 ms reset delay against system timing constraints. Verify that the absence of manual reset and watchdog features aligns with the design architecture before finalizing the selection.

Supervisors Part Context

This part belongs to the DS1233MS series of EconoReset circuits from Analog Devices/Maxim Integrated. These devices are specialized supervisory circuits intended for cost-sensitive applications requiring reliable power management. The MS suffix typically denotes the SOIC-8 surface-mount package variant within the broader product family.

Supervisors Replacement Considerations

Cross-reference other DS1233 variants such as DS1233Z-5+ for different package options like SOT-223-4. Check DS1233A-10+ for alternative threshold specifications if voltage requirements differ. Ensure pinout compatibility and thermal performance match the original design intent.
