DS1233MS-3+T&R

Supervisors Overview

The DS1233MS-3+T&R is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring power supply integrity in electronic systems. This component 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 accuracy of 10%. It provides a reset delay time of 350 ms and includes power-fail detection capabilities. The device draws a typical operating current of 50 uA and functions reliably across a temperature range of -40°C to +85°C. Packaged in SOIC-8 format, it offers an active low, open-drain output suitable for surface-mount applications without requiring manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Provides continuous voltage supervision with integrated power-fail detection to ensure system stability during abnormal power conditions.
• Features an active low open-drain output interface compatible with standard digital logic circuits for direct microcontroller integration.
• Operates with ultra-low quiescent current consumption to minimize power drain in battery-operated or energy-efficient designs.

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered equipment power monitoring
• Embedded controller voltage supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and package type. Ensure compatibility with required operating temperature ranges and supply voltage limits before integration. Confirm availability status through authorized distributors as supply constraints may apply. Cross-reference part numbers carefully to distinguish between similar variants within the DS1233 series that may differ in threshold voltages or output configurations.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with power-fail indication is required for systems operating between 1.2 V and 5.5 V. Consider the 4.375 V threshold and 350 ms reset delay for timing-sensitive applications. Evaluate the SOIC-8 surface-mount package for PCB space constraints. Verify that the open-drain output architecture aligns with the target system's input requirements and pull-up resistor specifications.

Supervisors Part Context

The DS1233 series represents a family of EconoReset voltage supervisors from Maxim Integrated, now part of Analog Devices. These components are engineered for cost-effective power management solutions in consumer electronics and industrial control systems. The MS variant specifically denotes the surface-mount package option, distinguishing it from through-hole alternatives like the TO-92 configuration found in other series members.

Supervisors Replacement Considerations

Consult official datasheets for cross-referencing with other DS1233 variants such as DS1233MS-5+T&R or DS1233A-10+T&R based on specific voltage threshold and package requirements.
