UCC39161DP

Overview

The UCC39161DP is a low-current hot-swap power manager manufactured by Texas Instruments. It integrates a high-side N-channel MOSFET and control circuitry for single-channel protection in 8-pin SOIC packages. The device operates within a 4V to 6V supply range, supporting up to 0.6A load current. Key electrical parameters include an internal switch with integrated gate drive, adjustable current limit, and thermal shutdown. It features programmable fault timeout and soft-start capabilities to manage inrush currents during board insertion.

Feature Summary

• Integrates a high-side N-channel MOSFET for compact solution design
• Provides complete hot-swap protection including overcurrent and thermal shutdown
• Features adjustable current limiting and programmable fault timeouts
• Includes soft-start functionality to control inrush current during power-up

Applications

• SCSI bus termination power management
• General purpose hot-swap controller applications
• Peripheral card insertion protection

Procurement Notes

Verify component status as the UCC39161DP is listed as obsolete by the manufacturer. Confirm availability of alternative sources or stock levels before finalizing procurement plans. Ensure that any substitute components meet the original electrical specifications and pinout requirements to maintain system compatibility without redesign.

Selection Notes

Select this component for low-voltage applications requiring integrated hot-swap protection. The 8-SOIC package suits space-constrained designs. Consider the 0.6A current limit when sizing for load requirements. Verify operating temperature range compliance for the specific environment. Evaluate the need for external components versus the integrated solution benefits.

Part Context

This part belongs to the UCC3916x series of hot-swap controllers from Texas Instruments. It is designed for managing power distribution in systems requiring safe insertion and removal of cards or modules. The series typically includes variants with different pin counts and current ratings to address various form factors and power needs in industrial and communication equipment.

Replacement Considerations

The UCC3915DP is identified as a similar replacement option. Verify pin compatibility and electrical parameter alignment before substitution. Ensure the alternative supports the required voltage and current specifications for the target application.
