DS1233M-5+TR

Supervisors Overview

The DS1233M-5+TR is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up 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 5%. It draws a working supply current of 50 uA and supports power failure detection. The component is housed in an SOIC-8 package, suitable for surface mount installation, and functions across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides automatic system reset when monitored voltage drops below or exceeds specified thresholds
• Includes power-fail comparator output to signal impending loss of main power supply
• Operates with low quiescent current consumption for efficient power management

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration distinct from tube variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 footprint matches the target PCB layout requirements. Validate that the 5V threshold aligns with the specific application voltage rails.

Supervisors Selection Notes

Select this component when a fixed 4.625 V threshold is required for single-input voltage monitoring. Consider the SOIC-8 package size constraints relative to available board space. Evaluate the 350 ms reset delay against the startup timing requirements of the connected microprocessor. Verify compatibility with the operating temperature range of the final assembly environment.

Supervisors Part Context

This part belongs to the DS1233 series of EconoReset supervisory circuits designed for cost-sensitive applications. It integrates essential reset generation and power-fail detection functions into a compact form factor. The series is characterized by low power consumption and reliable operation across standard industrial temperature ranges.

Supervisors Replacement Considerations

DS1233Z-5+ offers identical electrical specifications but utilizes an SOT-223-4 package instead of SOIC-8. Cross-reference pinouts carefully as package differences may require PCB redesign.
