onsemi Current Regulation/Management NCP81296MNTXG

The NCP81296MNTXG is a 50 A electronically resettable in-line fuse designed for high current applications, particularly in 12 V systems such as servers and base stations. It features a low on-resistance of 0.65 mOc, which helps minimize power loss and reduce overall solution size. The device supports a peak current output of up to 60 A and operates within a voltage range of 4.5 V to 18 V. This product integrates a power switch, hot-swap controller, and current sensing capabilities, allowing for precise monitoring and overload protection. Key features include programmable soft-start, multi-level current limit, and an accurate analog load current monitor. The NCP81296MNTXG also offers an auto-retry mode for fault recovery, fast short-circuit protection, and over-temperature shutdown. Housed in a compact 5 mm x 5 mm QFN32 package, the device operates over a temperature range of -40¬8C to 125¬8C and can be paralleled for applications requiring higher current handling. It includes built-in diagnostics for internal switch faults and provides a low-power auxiliary output voltage.
