UCC2913N

Overview

The UCC2913N is a single-channel hot swap voltage controller manufactured by Texas Instruments, designed for industrial temperature ranges. It operates within a supply voltage range of 8.5 V to 10.5 V and draws a typical operating supply current of 20 mA. The device supports adjustable current limiting and functions with negative floating inputs. It is housed in an 8-pin PDIP package and operates reliably between -40°C and +85°C.

Feature Summary

• Provides integrated protection against overcurrent and thermal faults during board insertion or removal
• Supports negative floating input configurations for high-side switching applications
• Features adjustable current limiting to protect downstream circuitry from surge currents

Applications

• Telecommunications backplane power distribution systems
• Industrial control modules requiring safe hot swapping capabilities
• Data acquisition cards inserted into chassis racks

Procurement Notes

Verify the specific suffix indicates the PDIP-8 through-hole package variant rather than surface-mount options. Confirm RoHS compliance status as detailed in official documentation. Ensure the industrial temperature grade matches system environmental requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust protection for negative voltage rails. The adjustable current limit allows customization for various load profiles. Ensure the PCB layout accommodates the through-hole package dimensions and thermal dissipation needs associated with the PDIP-8 form factor.

Part Context

This part belongs to the UCC2913 series of hot swap controllers. It serves as a dedicated solution for managing power delivery to removable modules. The series emphasizes reliability in harsh industrial environments while simplifying the design of complex power distribution networks.

Replacement Considerations

Check for UCC2913DG4 as a lead-free alternative within the same functional family. Verify pin compatibility and electrical specifications before substituting any other hot swap controller models.
