UC2543DW

Power Supply Controllers, Monitors Overview

The UC2543DW is a supervisory circuit manufactured by Texas Instruments, housed in a 16-pin SOIC package. It functions as a power supply monitor with a fixed output voltage of 2.5V. The device features an active low or open drain output configuration. It operates within a temperature range defined by its commercial grade classification.

Power Supply Controllers, Monitors Feature Summary

• Provides precise monitoring of power supply voltages
• Offers flexible output logic options including active low and open drain configurations

Power Supply Controllers, Monitors Applications

• 5G base station power systems for remote radio units
• Automotive instrument cluster displays and infotainment systems
• Industrial motor drives and servo controllers
• Telecommunications and networking equipment such as routers and switches

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix and tape/reel versus tube packaging options available from authorized distributors. Confirm RoHS compliance status and lead times directly with the supplier. Ensure the ordering part number matches the required package style and temperature rating to avoid integration errors in final assembly.

Power Supply Controllers, Monitors Selection Notes

Select this component when a dedicated voltage supervisor is required rather than a general-purpose PWM controller. The 2.5V reference makes it suitable for lower voltage digital logic monitoring. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate if the active low/open drain output meets the microcontroller input requirements of the target system design.

Power Supply Controllers, Monitors Part Context

This device belongs to Texas Instruments' line of supervisory circuits and power management ICs. It is distinct from their current-mode PWM controllers like the UC3825ADW or UC2843D8TR. While sharing the manufacturer, it serves a protective monitoring role rather than direct switching control, fitting into broader power management architectures.

Power Supply Controllers, Monitors Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing board designs before considering alternative vendors.
