Programmable Hot Swap Power Manager  
FEATURES  
DESCRIPTION  
Integrated 0.15Power MOSFET  
The UCC3912 Hot Swap Power Manager provides complete power man-  
agement, hot swap capability, and circuit breaker functions. The only com-  
ponent required to operate the device, other than supply bypassing, is the  
fault timing capacitor, CT. All control and housekeeping functions are inte-  
grated, and externally programmable. These include the fault current level,  
maximum output sourcing current, maximum fault time,and start-up delay.  
In the event of a constant fault, the Internal fixed 3% duty cycle ratio limits  
average output power.

Programmable Start Delay  
Fixed 3% Duty Cycle  
The internal 4 bit DAC allows programming of the fault level current from 0  
to 3A with 0.25A resolution. The IMAX control pin sets the maximum sour-  
cing current to 1A above the fault level when driven low, and to a full 4A  
when driven high for applications which require fast output capacitor charg-  
ing.  
Uni-Directional Switch  
Thermal Shutdown  
When the output current is below the fault level, the output MOSFET is  
switched on with a nominal on resistance of 0.15 . When the output cur-  
rent exceeds the fault level, but is less than the maximum sourcing level,  
the output remains switched on, but the fault timer starts charging CT.  
Once CT charges to a preset threshold, the switch is turned off, and re-  
mains off for 30 times the programmed fault time. When the output current  
reaches the maximum sourcing level, the MOSFET transitions from a  
switch to a constant current source.  
Fault Output Indicator  
Maximum Output Current can be set  
to 1A above the Programmed Fault  
Level or to a full 4A
