That 50 A figure is the current the internal FET can carry in the on-state — it is not a surge or pulse rating, so the BOM needs to budget the full load current below this ceiling with derating for ambient temperature. High-side sensing means the voltage drop across the internal sense element is measured on the input side of the load — the part regulates current by comparing that drop to an internal reference. The ±6 % accuracy tells you the actual current limit will fall within 47 A to 53 A at the setpoint, which matters when sizing the downstream PCB trace and connector for worst-case fault current. The 0.5 mm pitch QFN footprint is routable on a 4-layer board without microvias. CT is for prototyping or low-volume builds where the full reel quantity is not needed.","metaTitle":"onsemi NCP81296MNTXG Electronic Fuse, 50A, 32-LQFN","metaDescription":"onsemi NCP81296MNTXG SENSEFET electronic fuse, 50A output, ±6% accuracy, 4.5-18V input, -40 to +125°C, 32-LFQFN.
