What are the key features of UCC3917D?
- Single-channel hot swap controller with adjustable overcurrent threshold for flexible power rail protection
- Integrated gate drive for external N-channel MOSFET enabling low-cost power path solutions
- Floating topology supports positive supply rails from 9 V to 80 V for wide input range applications
What is UCC3917D used for?
The UCC3917D is designed for hot swap and inrush current control in telecom and server power systems where boards must be inserted or removed from live backplanes without disruption. It suits industrial equipment requiring protected 48 V or 24 V supply rails with adjustable current limiting down to milliamp levels. The device also fits redundant power architectures needing automatic fault isolation and recovery across 1-channel positive floating bus configurations.

Frequently Asked Questions
What supply voltage range does the UCC3917D support for hot swap control?
The UCC3917D operates on positive floating supply rails, supporting input voltages from approximately 9 V up to 80 V, making it suitable for 12 V, 24 V, and 48 V telecom bus applications where hot plug protection is required.
How does the adjustable overcurrent threshold work in the UCC3917D?
The UCC3917D uses an external sense resistor to set the overcurrent trip point, allowing designers to program current limits from tens of milliamps to several amps. When the sensed voltage exceeds the threshold, the controller turns off the external N-channel MOSFET within microseconds to protect the load and source.
Which package does the UCC3917D use and what are its pin count and temperature ratings?
The UCC3917D comes in a 16-pin SOIC (SOP16, 0.25-inch body) package rated for commercial temperature range. Its compact footprint with 1.27 mm pitch suits high-density PCB layouts in servers and industrial power modules requiring hot swap management.
Can the UCC3917D replace older hot swap controllers in 48 V telecom shelf designs?
Yes, the UCC3917D is a direct candidate for upgrading older 48 V hot swap designs because it supports floating positive rails up to 80 V, has a single-channel architecture with 1 control function, and uses a standard 16-pin SOIC footprint that is common across many legacy board layouts.
