This article discusses the challenges of designing high current, input circuit protection and how a hybrid hot swap circuit comprising an eFuse in parallel with regular hot-swap controller can protect the
The high-power consumption along with fast and transient dynamics impose challenges in designing front-end protection using a hot-swap controller and parallel MOSFETs.
Hot Swap circuits are used to allow for “Hot Plugging” of circuit boards into back planes. The applications that require such functionality are mission critical, such as servers and communications
This article explains the function and basic operation of a hot-swap controller and some of the schemes used to control inrush current. It discusses hot-swap controller features and trends,
The ADM1177 hot-swap controller performs additional functions. It has an integrated on-chip ADC that can be used to translate the supply voltage and load current into digital data—which can be read out
The ability to hot swap memory, drives, or other peripherals is a key functionality of server, computing, and telecom hardware. ON Semiconductor''s load switch and eFuse portfolios provide an easy,
Here is a short tutorial explaining the inner functioning a hot swap device while outlining key design challenges. It also includes hot swap circuit schematics and design examples.
Developed as a standard series of high efficiency, hot-swap front end power supplies, the HFE is available in three power levels, 1600W, 2500W and the new generation 3500W.
TI offers Excel-based calculators for Hot Swap with power limiting that follow the approach outlined here. Thus, engineers that want to understand the implementation and reasoning behind these tools will
