What are the key features of STEF512SRIPUR?
- Dual-channel eFuse protecting both 5 V and 12 V rails in a single IC
- Integrated reverse current blocking prevents back-powering of the supply
- Programmable overcurrent threshold with auto-retry or latch-off modes
- 20-pin SOIC package with 2 independent protection channels
- No external fuse replacement required — solid-state resettable protection
What is STEF512SRIPUR used for?
STEF512SRIPUR is used in server backplane systems, industrial motherboards, and embedded computing modules where both a 5 V logic rail and a 12 V power rail must be independently protected against overcurrent and reverse insertion faults. Its dual-channel architecture reduces the component count in hot-swap and board management controller designs compared to using two separate eFuse ICs.

Frequently Asked Questions
How does STEF512SRIPUR protect both 5 V and 12 V rails simultaneously in a server backplane design?
STEF512SRIPUR integrates 2 independent eFuse channels, one rated for the 5 V rail and one that also operates on 12 V supply. Each channel independently monitors current and can disconnect its rail within microseconds upon detecting an overcurrent event, preventing a single-rail fault from propagating to the other supply.
What reverse current protection does STEF512SRIPUR provide, and why is this important in hot-swap applications?
STEF512SRIPUR includes integrated reverse current blocking on both channels, preventing current flow back toward the source when a board is inserted into a powered backplane. This protects against voltage rail collapse during hot-swap events in systems where 5 V or 12 V boards may be inserted with residual charge on the load capacitors.
In what package does STEF512SRIPUR come, and how many pins does it expose for configuration and monitoring?
STEF512SRIPUR is housed in a 20-pin SOIC package with 0.127 mm pitch. The 20 pins provide connection for both power channels, fault flags, enable inputs, and current threshold programming resistors, allowing engineers to configure each channel independently without additional ICs.
When is STEF512SRIPUR a better choice than two separate single-channel eFuses for a dual-rail board design?
STEF512SRIPUR integrates 2 channels in a single 20-pin SOIC, saving approximately 30–50% board area compared to two 8-pin or 10-pin single-channel eFuses. It also simplifies BOM management for procurement teams, as one part number covers both the 5 V and 12 V protection functions.
