Advance Information  
1.0 A Negative Voltage Hot  
Swap Controller  
34653  
The 34653 is a highly integrated -48 V hot swap controller with an  
internal Power MOSFET. It provides the means to safely install and  
remove boards from live -48 V backplanes without having to power  
down the entire system. It regulates the inrush current, from the  
supply to the load’s filter capacitor, to a user-programmable limit,  
allowing the system to safely stabilize. A disable function allows the  
user to disable the 34653 manually or through a microprocessor and  
safely disconnect the load from the main power line.  
HOT SWAP  
The 34653 has active high and active low power good output  
signals that can be used to directly enable a power module load.  
Undervoltage and overvoltage detection circuitry monitors the input  
voltage to check that it is within its operating range. A start-up delay  
timer ensures that it is safe to turn on the Power MOSFET and charge  
the load capacitor.

98ASB42564B  
A two-level current limit approach to controlling the inrush current  
and switching on the load limits the peak power dissipation in the  
Power MOSFET. Both current limits are user programmable.
