Overview
The UC2914DW is a hot swap power manager from Texas Instruments designed for single-channel applications operating within a 5 V to 35 V supply range. It integrates comprehensive protection features including programmable current limiting, circuit breaker functionality, and fault timeout mechanisms. The device supports auto-retry modes and latched fault states to manage power insertion safely. It is housed in an 18-SOIC package and operates across an extended temperature range of -40°C to +85°C.
Feature Summary
- Integrates adjustable current limiting and circuit breaker protection for safe hot swapping
- Supports configurable fault handling with auto-retry or latched fault options
- Includes programmable fault timeout to prevent indefinite fault conditions
Applications
- PCI/PCI-X backplane power management
- Hot swap server blade insertion
- Telecommunications equipment power distribution
Procurement Notes
Verify component status as the UC2914DW may be classified as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing design specifications before procurement. Check for moisture sensitivity levels and storage requirements if sourcing from non-original channels.
Selection Notes
Select this component for designs requiring robust hot swap capabilities with integrated protection. Consider the 18-SOIC package constraints and thermal performance. Evaluate the need for programmable thresholds against fixed-parameter alternatives. Verify that the single-channel configuration meets system power distribution requirements without excessive channel count overhead.
Part Context
Part of the UC29xx series of hot swap controllers, sharing functional similarities with the UC3914DW but potentially differing in specific pinouts or feature sets. Belongs to the broader portfolio of power management ICs focused on safe power insertion and removal in high-reliability systems.
Replacement Considerations
UC3914DW is a related model within the same family. Verify pin-to-pin compatibility and feature equivalence before substitution. Consult official datasheets for detailed comparison of electrical characteristics and control logic.
