SC4250 Datasheet (Semtech) - Negative Voltage / Hot Swap Controller

SC4250, Negative Voltage / Hot Swap Controller

The SC4250 is a negative voltage hotswap controller that allows the insertion of line cards into a live backplane.

The inrush current is programmable, and the closed loop operation limits the maximum current even under short circuit conditions.

A built-in timing circuit prevents false shutdown.
