NCP81295MNTXG Description

Short technical summary and product information.

The ON Semiconductor NCP81295MNTXG is an electronically resettable, in-line fuse suitable for 12V high current applications like servers and storage systems. It features a co-packaged power switch, hotswap controller, and current sensor.

Key electrical specifications include a continuous current rating of 50A (up to 60A peak), an input voltage range of 4.5V to 18V, and a low 0.65 mΩ integrated MOSFET. The device offers ±6% accuracy for current monitoring and overload protection.

This electronic fuse operates within a temperature range of -40°C to 125°C. It is housed in a 32-LQFN (5x5 mm) package and is designed for surface mounting.

Additional features include programmable soft-start, multi-level current limit, analog load current monitor, over-current alert output, analog temperature output, and a status fault OK output. The NCP81295 variant offers latch-off protection, while the NCP81296 provides auto-retry mode.
