UC3914DWTR

Overview

The UC3914DWTR is a single-channel hot swap voltage controller manufactured by Texas Instruments, designed for commercial temperature applications. It operates within a supply voltage range of 5 V to 35 V and draws a typical operating supply current of 20 mA. The device is housed in an SOIC-18 surface-mount package and supports power failure detection capabilities. It functions as a dedicated controller for managing power insertion and removal in electronic systems.

Feature Summary

Provides integrated control for safe hot swapping operations
Includes built-in power failure detection functionality
Supports single-channel configuration for board-level power management

Applications

Server backplane power insertion and removal
Telecommunications equipment power modules
Industrial control system hot swap interfaces

Procurement Notes

Verify the specific suffix 'DWTR' against official Texas Instruments documentation to confirm tape-and-reel packaging and exact thermal grade specifications. Ensure compatibility with required operating temperature ranges and check for any recent lifecycle notices regarding obsolescence or replacement recommendations before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring controlled power insertion for single-rail applications. Consider the SOIC-18 package constraints and the 5 V to 35 V input range. Evaluate if the integrated power failure detection meets system reliability requirements without needing external circuitry for fault monitoring.

Part Context

This part belongs to the UC3914 series of hot swap controllers from Texas Instruments. It is categorized under PMIC - Power Management ICs. The device is distinct from PWM controllers like the UC3824 or PFC controllers like the UC3854, serving specifically for load switch and protection management rather than DC-DC conversion.

Replacement Considerations

Check official Texas Instruments resources for direct pin-to-pin replacements or upgraded versions within the UC39xx family. Verify if newer generations offer improved thermal performance or additional channels while maintaining the same SOIC-18 footprint.
