SC4150
Description
The SC4150 is a negative voltage hotswap controller that allows the insertion of line cards into a live backplane.
The inrush current is programmable and 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 SC4150 latches off under abnormal condition and attempts to restart after a time out period.
The device es in two options, PWRGD (SC4150H) and PWRGD (SC4150L). These signals can be directly used to enable power modules.
