UCC2912N

Overview

The UCC2912N is a single-channel hot swap voltage controller manufactured by Texas Instruments, designed for programmable switch power management. It operates within a supply voltage range of 3 V to 8 V and supports an adjustable current limit threshold. The device functions across an industrial temperature range from -40 °C to +85 °C. It is housed in a 16-pin Plastic Dual In-Line Package (PDIP) suitable for through-hole mounting. This component provides essential protection and control for backplane applications requiring safe insertion and removal of circuit boards.

Feature Summary

• Provides controlled inrush current limiting during board insertion to prevent bus voltage collapse
• Features adjustable current limit thresholds for customizable protection levels
• Supports safe hot swapping operations in high-density backplane systems

Applications

• High-density server backplanes
• Telecommunications equipment power distribution
• Industrial control system modules

Procurement Notes

Verify the package type matches your PCB footprint requirements, as this specific part number denotes the PDIP-16 through-hole variant. Confirm that the operating voltage range aligns with your system's power rails. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the datasheet for pinout compatibility with existing designs.

Selection Notes

Select this component when through-hole assembly is preferred over surface mount technologies for robust mechanical connections. Consider the UCC2912DP or UCC2912PWP if space constraints necessitate SOIC or TSSOP packages respectively. Evaluate the need for power fail detection features, which may vary between package variants within the same family.

Part Context

This device belongs to the UCC2912 series of hot swap controllers. It complements other Texas Instruments power management solutions like the UC2901 and UC2902 for complete load sharing and feedback generation in distributed power architectures. The series focuses on protecting power buses during thermal cycling and physical insertion events.

Replacement Considerations

The UCC2912DP and UCC2912PWP are functional equivalents within the same series but utilize different packages (SOIC and TSSOP). Verify pin-to-pin compatibility before substitution. No direct cross-brand replacements are documented in the provided data.
