DS1233M-5

Supervisors Overview

The DS1233M-5 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, belonging to the DS1233MS series. 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 threshold of 4.49 V. The device provides a reset delay time of 500 ms and consumes a typical operating supply current of 50 uA. It offers power-fail detection capabilities without manual reset or watchdog timer functions. The component is housed in an SOIC-8 surface-mount package and supports active low open-drain output configurations.

Supervisors Feature Summary

• Provides automatic system reset generation upon detecting power supply anomalies
• Includes dedicated power-fail signal output for advanced system protection
• Operates with low quiescent current suitable for battery-powered applications

Supervisors Applications

• Microprocessor system supervision
• Battery-operated electronic devices

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required package type and temperature rating for your application environment. Cross-reference part numbers carefully as minor suffix changes may indicate different packaging or testing standards.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with power-fail indication is required. Consider the 500 ms reset delay and 4.375 V threshold relative to your system's power-up sequence requirements. Evaluate the SOIC-8 package constraints against your PCB layout space and thermal management needs.
