The NCP81292 from onsemi is an Electronically Resettable eFuse IC that has been designed for high-current applications. It requires an input voltage of 4.5 - 18 V and provides an output current of up to 80 A. This eFuse IC includes an enable input for control, optional output pulldown when disabled, programmable soft-start, and multi-level current limit settings for efficient power management. It features an accurate analog load current monitor, programmable over current alert output, analog temperature output, and status fault OK output to provide comprehensive monitoring capabilities. This IC has a built-in insertion delay feature for hot-swap applications where devices are swapped while the system is running.
It incorporates an auto-retry mode that keeps operations running smoothly by dealing with issues like delayed current limits, fast short-circuit protection, shutting down in case of overheating, and managing soft-start duration. This device offers internal diagnostics to detect switch faults and has a low-power output option, managing power across different conditions. This eFuse IC is available in a surface-mount package that measures 5.30 x 5.30 mm and is ideal for servers, storage and base stations applications.
