description  
The UCC3915 programmable hot swap power manager provides complete power-management, hot-swap  
capability, and circuit breaker functions. The only external component required to operate the device, other than  
power supply bypassing, is the fault-timing capacitor, C . All control and housekeeping functions are integrated,  
T
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 2% duty cycle ratio limits  
average output power.  
The internal 4-bit DAC allows programming of the fault-level current from 0 A to 3 A with 0.25-A resolution. The  
IMAX control pin sets the maximum-sourcing current to 1 A above the trip level or to a full 4 A of output current  
for fast output capacitor charging. (continued)
