SC4150 Datasheet PDF - Semtech Corporation

Description
The SC4150 is a negative voltage hotswap controller that allows the insertion of line cards into a live backplane.

FEATUREs
◆ Programmable slew of the inrush current when used for hot insertion in the negative 24V and 48V backplane
◆ Closed loop operation limits the maximum current even in short circuit condition
◆ Built in timer prevents false shutdown, when the closed loop operation limits the current.
◆ Sensing the drain voltage allows for immediate shutdown in short circuit condition, where current spikes and noise is ignored.
◆ Power good signal
◆ Input UVLO and OVLO sensing
◆ SO-8 package

APPLICATIONs
◆ Central office switching
◆ -48V Distributed power systems
◆ Power supply hotswap & inrush control
