Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before procurement. Confirm RoHS compliance status through authorized distributors. Validate that the component meets all necessary safety and regulatory standards for the intended deployment environment.

Selection Notes

Select this component for single-channel hot swap applications requiring negative floating ground references. It is suitable for designs needing integrated power failure detection without external switches. Consider the SOIC-8 package size for space-constrained layouts. Evaluate thermal performance within the specified industrial temperature range during the design phase.

Part Context

The UCC2913D belongs to the UCC2913 series of hot swap controllers from Texas Instruments. This family provides comprehensive power management solutions for high-reliability systems. The device simplifies board-level protection by integrating control logic and monitoring functions into a compact footprint.

FAQ

Does the UCC2913D include an internal switch?

No, the UCC2913D is a controller only and requires an external N-channel MOSFET for switching operations.

What is the maximum operating voltage for this controller?

The maximum supply voltage rating is 10.5 V, though it is typically used in -48V systems with appropriate level shifting or sensing networks.
