Positive Floating Hot Swap Power Manager  
FEATURES  
DESCRIPTION  
• Manages Hot Swap of 15V and  
The UCC3917 family of positive floating hot swap managers provides complete  
power management, hot swap, and fault handling capability. The voltage limita-  
tion of the application is only restricted by the external component voltage limi-  
tations. The IC provides its own supply voltage via a charge pump off of VOUT.  
The onboard 10V shunt regulator protects the IC from excess voltage. The IC  
also has catastrophic fault indication to alert the user that the ability to shut off  
the output NMOS has been bypassed. All control and housekeeping functions  
are integrated and externally programmable. These include the fault current  
level, maximum output sourcing current, maximum fault time, soft start time,  
and average NMOS power limiting.  
Above  
• Precision Fault Threshold  
• Programmable Average Power  
Limiting  
• Programmable Linear Current  
Control  
• Programmable Overcurrent Limit  
• Programmable Fault Time  
The fault level across the current sense amplifier is fixed at 50mV to minimize  
total drop out. Once 50mV is exceeded across the current sense resistor, the  
fault timer will start. The maximum allowable sourcing current is programmed  
with a voltage divider from the VREF/CATFLT pin to generate a fixed voltage  
on the MAXI pin. The current level at which the output appears as a current  
source is equal to VMAXI divided by the current sense resistor. If desired, a con-  
trolled current startup can be programmed with a capacitor on MAXI.  
• Internal Charge Pump to Control  
External NMOS Device  
• Fault Output and Catastrophic  
Fault Indication  
• Fault Mode Programmable to  
Latch or Retry  
When the output current is below the fault level, the output device is switched  
on with full gate drive. When the output current exceeds the fault level, but is  
less than maximum allowable sourcing level programmed by MAXI, the output  
remains switched on, and the fault timer starts charging CT. Once CT charges  
to 2.5V, the output device is turned off and attempts either a retry sometime  
later or waits for the state on the LATCH pin to change if in latch mode. When  
the output current reaches the maximum sourcing current level, the output de-  
vice appears as a current source.

• Undervoltage Lockout
