Pin 5 serves as the lowest impedance to the electrical  
ground. Pins 4, 12, and 13, serve as heat sink/ground.  
These pins should be connected to large etch PCB areas  
to help dissipate heat.

description  
The UCC2918 low on-resistance hot swap power manager provides complete power management, hot swap  
capability, and circuit breaker functions. The only components needed to operate the device, other than supply  
bypassing, are a timing capacitor and two programming resistors. All control and housekeeping functions are  
integrated and externally programmable. These include the fault current level, maximum output sourcing  
current, maximum fault time, and startup delay. In the event of a constant fault, the internal fixed 3% duty cycle  
ratio limits the average output power. The IFAULT pin allows linear programming of the fault level current from  
0 A to 4 A.
