UCC2912NG4

Overview

The UCC2912NG4 is a 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 a single channel. The device features an adjustable current limit threshold with a maximum rating of 4 A. It is housed in a 16-pin DIP package and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Provides programmable control for safe insertion and removal of circuit boards in live backplane systems.
• Features adjustable thresholds for precise management of inrush current and overcurrent protection events.

Applications

• Hot-swap applications in telecommunications infrastructure
• Industrial computing systems requiring board insertion under power
• Server and storage backplanes

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the DIP-16 package variant matches the design requirements. Ensure the operating environment stays within the specified -40 °C to +85 °C range. Cross-reference the datasheet for any specific handling precautions related to humidity sensitivity classification.

Selection Notes

Select this component when a robust solution for managing power-up sequences and fault protection in high-current bus systems is required. The adjustable nature of the current limit allows customization for various load profiles. Consider the through-hole packaging if PCB assembly methods necessitate it over surface-mount alternatives within the same family.

Part Context

This part belongs to the UCC2912 series of hot-swap controllers. It shares functional similarities with other devices in the family but is distinguished by its specific package type and pin configuration. The series is designed to protect both the system bus and the inserted card during power transitions.

Replacement Considerations

The UCC2912N serves as the non-green equivalent. Verify pin compatibility and electrical specifications before substitution. Other members of the UCC291x family may offer different package options or slight parameter variations.
