DESCRIPTION  
The LM25069 positive hot swap controller provides  
intelligent control of the power supply voltage to the  
load during insertion and removal of circuit cards from  
a live system backplane or other "hot" power sources.  
The LM25069 provides in-rush current control to limit  
system voltage droop and transients. The current limit  
and power dissipation in the external series pass N-  
Channel MOSFET are programmable, ensuring  
operation within the Safe Operating Area (SOA). The  
POWER GOOD output indicates when the output  
voltage is within 1.3V of the input voltage. The input  
under-voltage and over-voltage lockout levels and  
hysteresis are programmable, as well as the initial  
insertion delay time and fault detection time. The  
LM25069-1 latches off after a fault detection, while  
the LM25069-2 automatically restarts at a fixed duty  
cycle. The LM25069 is available in a 10 pin VSSOP  
package.
