Overview

Negative Voltage Hot Swap Controller POWER MANAGEMENT Description 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.
The signal from the drain voltage is fed to the timer, providing safety for the MOSFET when in linear mode.
The SC4250 latches off under abnormal conditions The power has to be recycled in order to resume operation.
The device comes in two options, PWRGD (SC4250H) and PWRGD (SC4250L).
These high or low signals can be directly used to en...
