UC2914N

Overview

The UC2914N is a single-channel power supply support circuit manufactured by Texas Instruments. It is housed in an 18-pin PDIP package and operates within a temperature range of -40°C to +85°C. The device functions as a hot swap voltage controller, designed for industrial applications. Key electrical specifications include a maximum supply voltage of 35V and a minimum of 5V. It features a single channel with a typical operating supply current of 20mA. The component supports power failure detection and is classified under PMIC - Power Management ICs.

Feature Summary

• Provides hot swap voltage control for single-channel power supply systems
• Includes integrated power failure detection capabilities
• Supports isolated feedback generation for power loop management

Applications

• Industrial power supply protection circuits
• Hot swap backplane systems
• Power management integrated circuits requiring fault detection

Procurement Notes

Verify the specific revision code and manufacturing date code upon receipt, as this component may be subject to discontinuation notices from Texas Instruments. Confirm that the PDIP-18 package matches your PCB footprint requirements. Ensure compliance with RoHS directives if required for your specific assembly process. Check for any moisture sensitivity level (MSL) handling requirements during storage and reflow soldering procedures.

Selection Notes

Select the UC2914N when a robust solution for single-channel hot swap control is required in industrial environments. Consider its wide operating temperature range of -40°C to +85°C for harsh conditions. Compare it against other UC series controllers if multiple channels or different package types are needed. Verify that the 35V maximum supply voltage aligns with your system's power rail specifications.

Part Context

The UC2914N belongs to the UC29xx series of feedback loop power controllers and hot swap voltage controllers produced by Texas Instruments. This series is designed for managing power supply faults and enabling safe insertion and removal of modules. It complements other components like the UC2901 and UC3914 in comprehensive power management designs.
