DS1233-15/T&R

Supervisors Overview

The DS1233-15/T&R is a voltage supervisory circuit manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 4.0 V to 5.5 V and features a reset threshold voltage of 4.625 V with an accuracy of 5%. The device provides a reset delay time of 350 ms and includes power-fail detection capabilities. It utilizes an active low, open drain output configuration and lacks manual reset or watchdog timer functions. The component is available in TO-92-3 through-hole packaging and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors single input voltage for brown-out conditions
• Generates system reset signal upon power failure detection
• Provides stable reset output with defined delay timing

Supervisors Applications

• Microprocessor system supervision
• Power management monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and electrical tolerances. Ensure compatibility with existing board layouts regarding pinout and thermal requirements. Confirm availability status as distribution channels may indicate limited stock for this specific reel variant.

Supervisors Selection Notes

Select this component when a simple, low-cost voltage monitor is required for standard 5V logic systems. Consider the TO-92 package for through-hole assembly needs. Evaluate if the fixed threshold and lack of additional features like watchdogs meet the specific design constraints without requiring more complex supervisory ICs.

Supervisors Part Context

This part belongs to the DS1233 series of EconoReset circuits designed for basic voltage monitoring applications. It serves as a fundamental building block for ensuring reliable system startup and shutdown sequences in digital electronics where comprehensive power management is not required.

Supervisors Replacement Considerations

Check for direct equivalents such as the DS1233M-15+T&R for improved accuracy specifications. Verify pin compatibility before substituting with other voltage supervisor families from different manufacturers.
