POWER MANAGEMENT  
Description  
Features  
‹ Programmable slew of the inrush current when  
used for hot insertion in the negative 24V and 48V  
backplane  
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 op-  
eration limits the maximum current even under short cir-  
cuit conditions. A built in timing circuit prevents false shut-  
down. 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 condi-  
tion and attempts to restart after a time out period.  
‹ 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  
The device comes in two options, PWRGD (SC4150H)  
and PWRGD (SC4150L). These signals can be directly  
used to enable power modules.  
Applications  
‹ Central office switching  
‹ -48V Distributed power systems  
‹ Power supply hotswap & inrush control
