The Monolithic Power Systems MP5991GLU-Z is a hot-swap controller providing an integrated Intelli-Fuse power-path solution. Per its product identity it targets a 16V system with up to 50A current handling and an integrated 1mΩ RDS(ON) path. It is an active production device for protected power distribution.
The MP5991GLU-Z is used to safely insert and remove boards or loads from a live power supply, limiting inrush current and protecting against overcurrent and short-circuit faults. Hot-swap controllers with integrated fusing are common in servers, storage systems, and telecom equipment where high-availability hardware must be serviced without powering down. Power-systems and hardware engineers deploy devices like this on high-current 12V/48V-class distribution rails that require controlled, protected connection.
Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
